1,6-BIS(2-OXACYCLOHEXYL)-HEXANE-1,6-DIONES AND A PROCESS FOR PRODUCING THEM

摘要

A tetraketone of the formula WHEREIN THE GROUPS R are the same and each is H or CH3, is produced by a process which comprises reacting adipoyl dichloride with at least a 100 percent excess over the stoichiometric proportion of an enamine of a cyclohexanone, the cyclohexanone having the formula The tetraketone can be hydrolyzed to form a diketo-dicarboxylic acid of the formula WHICH IS USEFUL AS A CROSS-LINKING AGENT FOR POLYMERS.
