The present invention relates to a synthesis method for highly selective 2-methyl allyl chloride and a synthesis reactor thereof, wherein the 2-methyl allyl chloride is obtained by means of a gas chlorination reaction, using isobutylene and chlorine as raw materials, that is carried out in a microchannel reactor with a cooling surface. The isobutylene and chlorine are reacted in a T-shaped microchannel reactor, wherein the mixing speed is extremely fast, and at the same time, a large heat exchanging area per reaction volume unit can ensure that the reaction is carried out steadily at a substantially constant temperature with a good controllability; therefore, the side reaction caused by an overly-high local temperature can be effectively inhibited and the reaction selectivity is high, without generating a coking phenomenon.

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.
