Description

BACKGROUND OF THE INVENTION
This invention relates to alcohols and more particularly to energetic polynitro substituted diols.
Previously, polynitrodiols such as A-Diol and DINOL were used as components of energetic polymers. These diols are known to fragment easily with loss of formaldehyde and formation of labile dinitromethane derivatives. Thus when free hydroxy groups are present in the polymer they provide sites for initiation of thermal decomposition and chemical reactions (incompatibility with other ingredients, degradation during aging). In particular, it would be desirable to provide diols which will be more stable toward weak bases or nucleophiles such as water (atmospheric moisture) or oxygen and nitrogen containing components of energetic binder systems.
SUMMARY OF THE INVENTION
Accordingly, an object of this invention is to provide new energetic diols.
Another object of this invention is to provide new energetic diols which can be used as components in energetic propellant and explosive binders.
A further object of this invention is to provide new polynitro diols which resist deformylation by mild bases.
Yet another object of this invention is to provide new polynitro diols which are compatible with oxygen and nitrogen containing components of propellant and explosive composites.
These and other objects of this invention are accomplished by providing diols of the formula ##STR3## wherein R is --H, --NO, --NO2, --CN, --CH2 COOCH3, --CH2 COOCH2 C(NO2)2 CH3, or --CH2 COOCH2 C(NO2)3.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The compounds of the present invention are energetic diols of the formula ##STR4## and their corresponding diesters of the formula ##STR5## wherein R is --H, --NO, --NO2, --CN, --COOCH3, --COOCH2 C(NO2)2 CH3, or --COOCH2 C(NO2)3 and R' is an alkyl, fluoroalkyl, chloroalkyl, aryl, fluoroaryl, chloroalkyl, aralkyl, fluoroaralkyl, chloroaralkyl, or alkene group.
The critical feature of the diols of the present invention is that the gem-dinitro groups are located in the γ position to the hydroxy groups
--C(NO.sub.2).sub.2 CH.sub.2 CH.sub.2 OH.
In similar prior art diols the gem-dinitro groups are located in the β position adjacent to the hydroxy groups
--C(NO.sub.2).sub.2 CH.sub.2 OH.
As stated in the background of the invention, these prior art diols are known to fragment easily in the presence of oxygen or nitrogen containing components of energetic binder systems. As a result, loss of formaldehyde and formation of labile dinitromethane derivatives occurs. Polymers made with these β-dinitro diols are therefor less stable. In the present diols, the additional methylene group between the gem-dinitro and the hydroxy group prevents the deformylation reaction. Therefore, binder polymers made with these new diols will be much more stable than those of the prior art. The addition of still more methylene groups is not desirable as they will lower the energy content of the present diols without significantly improving their stability.
5-aza-3,3-7,7-tetranitrononane-1,9-diol can be prepared by reacting one mole of ammonia with two moles of 2,2-dinitrobutane-1,4-diol under the conditions given in example 7. ##STR6## A method of preparing 2,2-dinitrobutane-1,4-diol is disclosed in U.S. Pat. Ser. No. 492,277, filed on May 6, 1983, entitled "2,2-Dinitrobutane-1,4-diol and Monoesters," by Horst G. Adolph and Michael Sitzmann, which was filed concurrently with the present case, herein incorporated by reference. In the process, 3,3,3-trinitropropanol is reacted with potassium iodide to produce the salt potassium 3,3-dinitropropanol.
C(NO.sub.2).sub.3 CH.sub.2 CH.sub.2 OH+KI→K.sup.+  .sup.- C(NO.sub.2).sub.2 CH.sub.2 CH.sub.2 OH.
The salt is then reacted with formaldehyde and the solution is acidified to yield the 2,2-dinitrobutane-1,4-diol ##STR7##
5-aza-3,3,7,7-tetranitrononane-1,9-diol-1,9-diesters of the formula ##STR8## can be formed by reacting one mole of ammonia with two moles of a monoester of the formula ##STR9##
The monoester may be prepared according to the procedure disclosed in U.S. Patent Application Ser. No. 492,277, filed on May 6, 1983, entitled "2,2-DINITROBUTANE-1,4-DIOL AND MONOESTERS," supra, which was filed concurrently with the present application, and herein incorporated by reference. First, 3,3,3-trinitropropanol is esterified by conventional means to produce a compound of the formula ##STR10## For example, the alcohol may be reacted with the appropriate acid chloride ##STR11## Example 2 illustrates this step for R' equal to --CH3 ##STR12##
Next, the ester is reacted with potassium iodide to produce a potassium salt ##STR13## Example 3 illustrates this step for R' equal to --CH3 ##STR14##
Reaction of the potassium salt of the ester, formaldehyde, and ammonia yields the desired diester ##STR15## Example 4 illustrates this step for R equal to --CH3 ##STR16## The ester groups can be hydrolyzed off by conventional means (for instance see Example 6). Because the ##STR17## serves only as a blocking group and is later hydrolyzed off, selection of R is not critical. For example, R may be an alkyl, fluoroakyl, chloroalkyl, aryl, fluoroaryl, chloroalkyl, aralkyl, fluoroaralkyl, chloroaralkyl, or alkene group. The only restrictions are that R should contain no groups that will interfer with the esterification of the 3,3,3-trinitropropanol or with the reaction between the 2,2-dinitrobutane-1,4-diol monoester and ammonia. (Amino and hydroxy containing groups are therefore not included in R.) As a practical matter, R is preferably low in molecular weight. For example, when R is an alkyl, fluoroalkyl, or chloroalkyl group, R preferable contains from 1 to 12, and more preferably from 1 to 4 carbon atoms. When R is an aryl, fluoroaryl, or chloroaryl groups, R preferably contains from 6 to 18, and more preferably 6 carbon atoms. When R is an aralkyl, fluoroalkyl, or chloroaralkyl group, R preferably contains from 7 to 18, and more preferably from 7 to 10 carbon atoms. Of all the groups available, R equals to --CH3 is most preferred for industrial purposes because of cost.
Other common examples are R equal to --CH═CH2, ##STR18## --CF3, --CCl3, etc.
The 3,3,7,7-tetranitro-5-azanonane-1,9-diol and its 1,9-diester derivatives are secondary amines with an active N-hydrogen which can be replaced with a more energetic group. For instance, Example 5 illustrate the nitration of the diacetate to form 3,3,5,7,7-pentanitro-5-azanonane-1,9-diol-1,9-diacetate using 90% nitric acid and acetic anhydride, ##STR19## Example 6 shows the acid hydrolysis of this diacetate to form 3,3,5,7,7-pentanitro-5-azanonane-1,9-diol, ##STR20##
Acetic acid and sodium nitrite, NaNO2, have been used under standard conditions to nitrosate 3,3,7,7-tetranitro-5-azanone-1,9-diol-1,9-diacetate to form 3,3,7,7-tetranitro-5-nitroso-5-azanonane-1,9-diol-1,9-diacetate ##STR21## Similarly, acetic acid and sodium nitrite may be used under standard conditions to nitrosate 3,3,7,7-tetranitro-5-azanone-1,9-diol to form 3,3,7,7-tetranitro-5-nitroso-5-azanone-1,9-diol. ##STR22##
3,3,7,7-tetranitro-5-cyano-5-azanonane-1,9-diol
[HOCH.sub.2 CH.sub.2 C(NO.sub.2).sub.2 CH.sub.2 ].sub.2 NCN
and its diester derivatives (e.g., 3,3,7,7-tetranitro-5-cyano-5-azanonane-1,9-diol 1,9-diacetate where R'=CH3) ##STR23## can be prepared by reaction of the corresponding secondary amines with cyanogen bromide.
By reacting 2 moles of a 4-monoester of 2,2-dinitrobutane-1,4-diol with glycine ##STR24## the 1,9 diester can be produced. The carboxylic acid group on the N,N-disubstituted glycine product could then be esterified with the appropriate alcohol by standard methods. For instance if methanol is used the product ester would be [HOCH2 CH2 C(NO2)2 CH2 ]2 NCH2 COOCH3. If 2,2-nitropropanol is used the product ester would be [HOCH2 CH2 C(NO2)2 CH2 ]2 NCH2 COOCH2 C(NO2)2 CH3. Finally, if 2,2,2-trinitroethanol is used, the product ester will be [HOCH2 CH2 C(NO2)2 CH2 ]2 NCH2 COOCH2 C(NO3)3. Alternately, the 1,9-ester groups could be hydrolyzed off by conventional means to yield the diol ##STR25##
The feasibility of these glycine syntheses is illustrated by similar syntheses in "The Mannich Reaction of 2,2-Dinitro-1-alkanols with Ammonia, Glycine and Hydrazine," by Milton B. Frankel and Karl Klager, Journal of the American Chemical Society, Vol. 79, pp. 2953-6 (1957), herein incorporated by reference. In particular the following 2 Examples are quoted from that article p. 2954, col. 2:
Bis-(2,2-dinitropropyl)-glycine (IV). A solution of 7.5 g. (0.1 mole) of glycine, 4.0 g. (0.1 mole) of sodium hydroxide and 50 ml. of water was mixed with 15.0 g. (0.1 mole) of 2,2-dinitropropanol. The temperature rose to 42° and the yellow solution formed was allowed to stand overnight. Upon addition of dilute sulfuric acid a viscous, colorless oil separated and solidified on standing. The product 15.6 g. (92.0%) was collected and recrystallized from methanol-water to give white crystals, m.p. 123°-124°.
Methyl Bis-(2,2-dinitropropyl)-glycine. A mixture of 20 g. (0.059 mole) of bis-(2,2-dinitropropyl)-glycine, 100 ml. of methanol and 10.0 ml. of concentrated sulfuric acid was refluxed for 90 minutes. The solution was diluted with 250 ml. of methylene chloride and washed with water, 5% sodium carbonate solution and water. The solvent was evaporated to yield 14.0 g. (67.3%) of white solid. Recrystallization from methanol-ether gave crystals, m.p. 94°-95°.
The general nature of this invention having been set forth, the following examples are set forth as specific illustrations thereof. It will be understood that the invention is not limited to these specific examples but is susceptible to various modifications that will be recognized by one of ordinary skill in the art.
Example 1 Preparation of 3,3,3-trinitropropanol
4,4,4-Trinitrobutyric acid (210 g, 0.94 mol) was added to 534 ml (908 g) of trifluoromethanesulfonic acid stirred in a 2000 ml, 3-neck, round-bottom flask. The solution was heated to 60° C. (oil bath) and sodium azide (100 g, 1.54 mol) was added in approximately 2 g portions over a six-hour period. (A stream of nitrogen was kept flowing over the reaction mixture during the addition to dilute and expel excess HN3.) Stirring was stopped and the thick mixture was heated overnight at 50° C. before it was poured onto ice to give an aqueous solution (2500 ml) which was extracted with 3×300 ml of methylene chloride. Two grams of unreacted trinitrobutyric acid were recovered from the CH2 Cl2 extracts. The aqueous solution was cooled at 10°-14° C. while a solution of 140 g of sodium hydroxide in 200 ml of water was added dropwise with good stirring. The solution was then heated to 35° C. before a solution of 121 g (1.75 mol) of sodium nitrite in 400 ml of water was added over a 30 minute period. (Some cooling was necessary to maintain the temperature at approximately 40° C. during the addition.) The solution was heated at 60° C. for one and a half hours before it was cooled to 25° C. and extracted with 2×500 ml methylene chloride. It was then saturated with sodium chloride and extracted with 3×500 ml CH2 Cl2. The combined extracts contained 161 g (87.7 percent) of crude 3,3,3-trinitropropanol.
EXAMPLE 2 Preparation of 3,3,3-Trinitropropyl Acetate
Acetyl chloride (125 ml) was added to a dried (MgSO4) solution of 150 g of crude 3,3,3-trinitropropanol as prepared above and cooled in an icebath. The solution was slowly warmed to reflux temperature and held overnight. The reaction solution was concentrated to 800 ml by distillation before it was cooled and poured onto ice water. The mixture was stirred for 30 minutes before the CH2 Cl2 layer was separated, dried over MgSO4, and the solvent removed to give 183 g (100 percent) of crude 3,3,3-trinitropropyl acetate as a light green solid. A similar reaction employing 31.9 g of crude 3,3,3-trinitropropanol, 50 ml of methylene chloride and 25 ml of acetyl chloride gave, after addition of hexane to the CH2 Cl2 solution and chilling, filtering off the solid, concentrating and chilling again, 34.5 g (88.9 percent) of 3,3,3-trinitropropyl acetate. A second recrystallization from CH2 Cl2 /hexane gave material of mp 47°-49° C.; .sup. 1 H NMR (CDCl3); δ2.06 (s, 3H), 3.45 (t, 2H), 4.55 (t, 2H).
Analysis:
Calculated for C5 H7 N3 O8 : C, 25.32; H, 2.98; N, 17.72. Found: C, 25.31; H, 3.01; N, 17.27.
EXAMPLE 3 Preparation of Potassium 3,3-Dinitropropyl Acetate
Potassium iodide (338 g, 2.03 mol) was added to 183 g (0.77 mol) of crude 3,3,3-trinitropropyl acetate in 2100 ml of methanol. The mixture was stirred at 40° C. for 24 hours before it was cooled to 20° C. and the yellow salt removed by filtration. The product was stirred with 600 ml of methanol at 20° C. to give 88.5 g (50 percent) of yellow salt.
A similar reaction using 32.1 g of purified 3,3,3-trinitropropyl acetate gave 20.4 g (66 percent) of potassium 3,3-dinitropropyl acetate. 1 H NMR (D2 O with TMS capillary): δ2.54 (s, 3H), 3.94 (t, 2H), 4.93 (t, 2H).
EXAMPLE 4 Preparation of 3,3,7,7-Tetranitro-5-azanonane-1,9-diol-1,9-diacetate
A solution of potassium 3,3-dinitropropyl acetate (87 g, 0.38 mol) in 1050 ml of distilled water and 84 ml of 36 percent formalin was stirred in an ice bath while 45 ml of concentrated hydrochloric acid was added (pH approximately 3). The mixture was heated at 40° C. for 30 minutes, then cooled to 20° C. and 42.6 g of ammonium chloride was added. The mixture was stirred vigorously in an ice bath while concentrated ammonium hydroxide solution was added over several hours until the aqueous phase remained yellow and the pH was 5.5 to 6. At this point an appreciable amount of semisolid had separated from solution and adhered to the walls of the flask. The mixture was stirred overnight before the semisolid was extracted into methylene chloride. Addition of hexane and cooling to 5° C. gave 58.1 g of white crystals, mp 75°-76° C. The mother liquor was cooled in dry ice-acetone to give a semisolid which was stirred with water and then crystallized from methylene chloride-hexane to give an additional 3.0 g of product, mp 66°-70° C. Total yield (61.1 g) is 76 percent of theoretical. The analytical sample had mp 75.5°-76° C. 1 H NMR (CDCl3): δ2.06 (s, 3H), 2.91 (t, 2H), 3.85 (d, 2H), 4.27 (t, 2H).
