| Zusammenfassung: | The present invention relates to a method for preparing 2,3-dichloropropylene, which solves the problems of low product yield and high production costs in the prior art. A catalyst TEBA is added in the reacting procedure of 1,2,3-trichloropropane and liquid alkali for making 2,3-dichloropropylene. And as an improvement, the invention takes allyl chloride as an initial raw material to react 1,2,3-trichloropropane with chlorine in advance. The present invention adopts solventless manufacturing technique so as to reduce material cost, and TEBA is taken as a catalyst to improve the product quality and yield. |
