Document Type and Number:
WIPO Patent Application WO/2019/153773
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for high-content 2-methallyl chloride. the high-content 2-methallyl chloride is obtained by using a chlorination reaction solution obtained by means of the reaction of isobutene and chlorine as a raw material, and continuously rectificating the chlorination reaction solution by an isobutyl chloride separation tower, an isocrotyl chloride separation tower, and a 2-methallyl chloride separation tower, wherein an extractive rectification method is used in the separation of isocrotyl chloride. The present invention has the advantages of a small number of rectification towers required for separation, high content of obtained 2-methallyl chloride, and low energy consumption.
