3-methyl-3-butene-1-ol is usually obtained by Prins reaction with isobutene catalyzed by organic base after full depolymerization of polyformaldehyde.When methanol is used as solvent in traditional method,it is easy to condense with formaldehyde to reduce the yield;When tert-butanol is used as sol-vent,it is easy to coagulate during recovery,resulting in pipeline blockage.This paper uses methyl-acetal as solvent to solve the above problems,studies the synthesis of 3-methyl-3-butene-1-ol in tube reactor,and optimizes the depolymerization conditions and Prins condensation conditions to obtain the best reaction conditions.The reaction time is greatly reduced and the reaction efficiency is improved.
