The preferred forms of invention
At first I of the present invention is elaborated.
Among the I of the present invention, the alicyclic epoxy compound (A) represented with above-mentioned general formula (I) is that the following aliphatics percarboxylic acids of 2 weight % is made the ester ring type olefin(e) compound oxidation of general formula (II) expression with water content.
As the ester ring type olefin(e) compound of raw material synthetic normally by the dehydration reaction of the compound that has corresponding hydroxyl.
The represented ester ring type olefin(e) compound of general formula (II) is opened clear 48-29899 communique, spy as the spy and is opened clear 58-172387 communique, spy and open as described in the 2000-169399 communique, for example can be synthesized by the compound with hexalin structure.Shown in (II), the ester ring type olefin(e) compound of gained is preferably with respect to having two keys on 3,4 of substituent X, preferably having hydroxyl with respect on 4 of substituent X as the compound that has hydroxyl of the raw material of ester ring type olefin(e) compound.
These compounds comprise the compound that contains the cyclohexane ring that is connected with hydroxyl at least more than 2 in the molecule for example since with above-mentioned identical reason, the present invention is effective especially for its dehydration reaction.
The compound that contains the cyclohexane ring that is connected with hydroxyl at least more than 2 in the molecule, for example can enumerate: the hydrogenation xenol, two (hydroxy-cyclohexyl) methane (dicyclohexanol methane), two (dimethyl hydroxyl cyclohexyl) methane (bis (dimethylcyclohexanol) methane), 1,2-two (hydroxy-cyclohexyl) ethane, 1,3-two (hydroxy-cyclohexyl) propane, 1,4-two (hydroxy-cyclohexyl) butane, 1,5-two (hydroxy-cyclohexyl) pentane, 1,6-two (hydroxy-cyclohexyl) hexane, 2,2-two (hydroxy-cyclohexyl) propane, two (hydroxy-cyclohexyl) phenylmethane, α, α-two (4-hydroxy-cyclohexyl)-4-(4-hydroxyl-α, the alpha-alpha-dimethyl cyclohexyl)-ethylbenzene, 3,3-two (hydroxy-cyclohexyl) pentane, 5,5-two (hydroxy-cyclohexyl) heptane, ten dihydro fluorenes glycol (dodecahydrofluorene diol), three (hydroxy-cyclohexyl) methane, three (hydroxy-cyclohexyl) ethane, 1,3,3-three (hydroxy-cyclohexyl) butane, four (hydroxy-cyclohexyl) ethane, 2,2-two [4,4 '-two (hydroxy-cyclohexyl) cyclohexyl] propane, A Hydrogenated Bisphenol A C (C: hexanaphthene), hydrogenation polyphenol etc. and their mixture.
The epoxidizing agent aliphatics percarboxylic acids that preferably water content is low that can when the double bond epoxidation of ester ring type olefin(e) compound, use.This is because if carry out epoxidation reaction in the presence of water, and the ring-opening reaction of epoxy group(ing) can take place, thereby has reduced the productive rate of epoxy compounds.
For this reason, the water content of aliphatics percarboxylic acids must be preferably below the 1 weight % for below the 2 weight %, more preferably below the 0.8 weight %, also will be preferably below the 0.6 weight %.
