128.17kg of 3,4-epoxycyclohexyl-1-methanol, 312.36kg of 3,4-epoxycyclohexyl-1-methyl carboxylate, 9.61kg of tetrabutoxytitanium were added to the 500L reactor, and reacted at 100°C 7 hours (there is no apparent liquid steaming out at this time, sampling GC detection 3,4-epoxycyclohexyl-1-methanol content≤1.0wt%), stop the reaction; The reaction solution is at 500Pa vacuum, 95 vacuum distillation to remove excess Methyl 3,4-epoxycyclohexyl-1-carboxylate, the concentrated solution was distilled by molecular distillation, vacuum distillation at 2Pa, 144°C under reduced pressure to obtain 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate.
