Description
. n d StatCs This invention relates to' new compositions of. matter and methods of synthesizing them. In particular, it relates to metal-aci-salts of nitroalkyls having the general formula:
NO: I
M- --CH2R wherein M is a metal radical of an alkali or alkaline earth metal element, and R is a nitroalkyl radical.
The polynitro compounds of this invention, because of their favorable oxygen balance, find valuable use as burning rate accelerators for rocket propellants. In addition, they are useful as high explosives and can be used in any conventional explosive missile, projectile, rocket, or the like, as the main explosive charge. An example of such a missile is disclosed in US. Patent No. 2,470,162, issued May 17, 1949. One way of using the high explosives in a device such as that disclosed in US. Patent No. 2,470,162 is to pack the crystalline explosive in powder form into the warhead of the missile. Alternatively, the crystals can be first pelletized and then packed. A charge thus prepared is sutficiently insensitive to withstand the shock entailed in the ejection of a shell from a gun barrel or from a rocket launching tube under the pressure developed from ignition of a propellant charge, and can be caused to explode on operation of an impactor time-fuse mechanism firing a detonating explosive such as lead azide or mercury fulminate.
The nitro compounds of this invention are conveniently prepared in accordance with the general reaction scheme set forth below:
wherein X is a halogen radical, M and R are as. defined above, and R is an alkyl radical.
The following examples are presented to more clearly illustrate my invention. It should be understood that these examples are intended to merely illustrate the invention, and should not be interpreted to limit the scope of this invention in any manner.
EXAMPLE I Formation of sdium-aci-1,1 ,3-trinitrobutane from sodium-aci-nitro-ethane A S-necked reactor was fitted with a mechanical stirrer, thermometer and dropping funnel and charged with a suspension of 490 gm. mole) of sodium nitroethane and 1500 ml. of methanol. A solution of 640 gm. (2.5 mole) of 2-bromo-2,2-dinitroethyl acetate in 1500 ml. of methanol was added while maintaining the temperature between -15" C. The white suspension of the salt became orange as the reaction proceeded and gradually Went into solution. The solution was evaporated to atent dryness leaving an orange salt; this salt being sodium-aci- 1, 1,3 -trinitrobutane.
EXAMPLE II A 3-necked flask, fitted with a mechanical stirrer, thermometer, and dropping tunnel was charged with 1 mole of 1,1-dinitroethane. The reactor was cooled inan ice bath and a solution containing 1 mole of sodium hydroxide in water was added. To this solution, a solution of 2-bromo-2,2-dinitroethyl acetate in methanol was added dropwise with stirring until half a mole of the 2-bromo- 2,2-dinitroethyl acetate had been added. The solution to which the methanol solution was added was maintained at 10 C. until the dropwise addition of the latter was completed. The final solution was allowed to warm to room temperature with stirring, after which it was ex.- tracted with ether to remove any unreacted starting materials. The aqueous layer resulting from the ether extraction was to 5" C. This layer contained sodium-acito the desired metal salt by the action of an alkali or alkaline earth metal iodide in alcoholic solution. The
following examples are provided to more clearly illustrate this alternative synthesis.
EXAMPLE Ill Preparation of 1-br0mo-l,1,3,3-tetranitr0'batane An aqueoussolution of sodium-aci-l,l,3,3-tetranitrobutane was cooled to about 5 C. and treated with 0.5 mole of bromine. The solution was extracted with ether and then dried and concentrated. 1-br0mo-1,1,3,3-tetranitrobutane was obtained in good yield.
EXAMPLE IV Preparation of potassium-aci-l ,1 ,3,3-tetranitrobutane l-bromo-1,1,3,3-tetranitrobutane was methanol and cooled to 0 C. The. solution was treated with potassium iodide in 50% methanol. A purple reaction mixture formed which was filtered off leaving a yellow salt, which was washed with ether and recrystal lized from ethanol. The product was subsequently identified as potassium-aci-l,1,3,3-tetranitrobutane, having a melting point of 137-138" C. Analysis was as follows: Calculated: percent C, 17.39; percent H, 1.83; percent N,
20.29. Found: percent C, 17.71; percent H, 1.83; percent N, 20.69. a
While the examples have been limited to the use of romine compositions as starting materials, the other halogens can also be employed in this reaction. Similarly, any of the alkali and alkaline earth metal nitroalkyl compounds can be reacted to effect a direct synthesis'of themetal salts of this invention.
Thus, esters such as 2-chloro-2,2-dinitro-ethyl propio-' nate; 2-iodo-2,2-dinitroethyl valerate; and 2-fluoro-2,2- dinitroethyl butyrate react with lithium-aci-Ll-dinitrw propane; magnesium-aci-l,1,3,3-tetranitrobutane; and calcium-aci-l,1,3,3-tetranitropentane to yield lithium-aci-l, 1,3,3-tetranitropentane; magnesium-aci-l,1,3,3,5,5-hexanitrohexane; and calcium-aci-1,l,3,3,5 ,S-hexanitroheptane, respectively. It is apparent that any member of my series of new compounds can be produced by reacting appropriate starting materials as taught herein.
Reaction temperature is not critical in the practice of the present invention, the only eifect of temperature variation being a corresponding increase or decrease in the rate of reaction.
