| Zusammenfassung: | The invention discloses a preparation method of vinylene carbonate, and belongs to the field of organic synthesis. Specifically, the preparation method comprises the following steps: (1) dispersing chloroethylene carbonate in liquid paraffin, and gasifying to form a gas-phase material flow; and (2) introducing the gas-phase material flow into a reaction pipeline preheated to a reaction temperature, and carrying out a cracking reaction to obtain vinylene carbonate, wherein the reaction temperature ranges from 350 DEG C to 600 DEG C. The preparation method is low in cost, simple to operate, high in efficiency and beneficial to industrial production. # imgabs0 #
