CONTINUOUS METHOD FOR PRODUCING METHYL VINYL ETHER

摘要

The invention relates to a method for continuously producing methyl vinyl ether by reacting methanol with ethyne in the liquid phase in the presence of a basic alkali metal compound or alkaline earth metal compound at a temperature ranging from 40 to 300 DEG C and under a pressure ranging from 0.1 to 5 MPa abs. According to the invention, the reaction is carried out in the absence of a continuous gas phase and with a methyl vinyl ether concentration in the entire liquid phase of = 30 % by weight.
