Abstract
Disclosed is an HFO-1234ze and HFC-245fa co-production preparation method. The HFO-1234ze and HFC-245fa are prepared through a two-stage gas phase fluorination reaction by using 1,1,1,3,3-pentachloropropane (HCC-240fa) as a raw material. With the processing method of the present invention, HFO-1234ze and HFC-245fa can be prepared at the same time, and the alkene is unlikely to polymerize or carbonize during the reaction, thus being suitable for industrialized promotion.
