(57) [Abstract] [Purpose] To produce bisperoxyketal, which is useful as a polymerization initiator, curing agent, and crosslinking agent for vinyl monomers, in high yield, safely and economically. [Structure] When a ketone and an alkyl hydroperoxide are reacted in the presence of an acidic catalyst, a polar solvent and a desiccant are used in combination to give a compound of the general formula: (In the formula, R 1 , R 2 and R 3 are a hydrogen atom or a carbon number 0. The to 3 alkyl group, R 4 represents an alkyl group having 1 to 3 carbon atoms, R 5 and R 6, the R 5 if each separating the alkyl group having 1 to 3 carbon atoms, R 6 represents an alkyl group having 2 to 10 carbon atoms, a cycloalkyl group or an aryl group, and when they are bonded, represents a cycloalkane structure. ) To obtain the bisperoxyketal. |
