A method of making an ester comprised of at least one cyclohexene oxide moiety is provided, involving the steps of a) esterifying an alcohol with a carboxylic acid-substituted cyclohexene to obtain an intermediate comprised of at least one carboxylate-substituted cyclohexene moiety; and b) epoxidizing the intermediate obtained in step a) with an epoxidizing agent to obtain the ester comprised of at least one cyclohexene oxide moiety. The esters have utility as acid scavengers, plasticizers and reactive resins.

[EN] A process for producing an epoxide such as a cycloaliphatic diepoxide by the reaction of an olefin such as a cycloaliphatic diene with hydrogen peroxide (H2O2) as an oxidant in the presence of a catalytic system under pH control for example at a pH of less than about 5. The present invention is advantageously used for the epoxidation of olefinic compounds such as olefins and aliphatic or aromatic dienes. [FR] L'invention concerne un procédé de production d'un époxyde, tel qu'un diépoxyde cycloaliphatique, par réaction d'une oléfine, telle qu'un diène cycloaliphatique, avec du peroxyde d'hydrogène (H2O2) utilisé comme oxydant, en présence d'un système catalytique et sous contrôle de pH, à un pH inférieur à environ 5, par exemple. La présente invention est utilisée avantageusement pour l'époxydation de composés oléfiniques, tels que des oléfines et des diènes aliphatiques ou aromatiques.
