Document Type and Number:
WIPO Patent Application WO/2019/019557
Kind Code:
A1
Abstract:
A method for co-production of a low-carbon foaming agent. 1,1,1,3,3-pentachloropropane and hydrogen fluoride are preheated and then introduced into a reactor, and react in the presence of a catalyst to obtain a reaction product, and the reaction product is separated and purified to obtain the following low-carbon foaming agent products: trans-1,3,3,3-tetrafluoropropene, cis-1,3,3,3-tetrafluoropropene, 1,1,1,3,3-pentachloropropane, trans-1-chlorine-3,3,3-trifluoropropene, and cis-1-chlorine-3,3,3-trifluoropropene. The method is simple in process, green and environment-friendly, high in production efficiency, and low in cost.
