Patent ID: 10689315

Abstract:
The invention discloses a method for co-operating low-carbon foaming agents, comprising: preheating 1,1,1,3,3-pentachloropropane and hydrogen fluoride and then introducing into a reactor to have a reaction in the presence of a catalyst to obtain a reaction product, and separating and purifying 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-pentafluoropropane, trans-1-chloro-3,3,3-trifluoropropene, cis-1-chloro-3,3,3-trifluoropropene. The invention has the advantages of simple process, environmental friendliness, high production efficiency and low cost.
