Patent ID: 8436217

Claim:
An integrated manufacturing process for co-producing 1,1,1,3,3-pentafluoropropane (245fa), trans-1-chloro-3,3,3-trifluoropropene (1233zd(E)), and trans-1,3,3,3-tetrafluoropropene (1234ze(E)) comprising the steps: (a) reacting 240fa, or a derivative thereof selected from 1,1,3,3-tetrachloropropene and 1,3,3,3-tetrachloropropene, with HF in the presence of a catalyst to form a mixture containing HCl, HF, an organic mixture of 244fa, 245fa, 1233zd and 1234ze; (b) removing the HCl and HF from the mixture of step (a) and then reacting the organic mixture with HCl in the presence of a catalyst to convert the unsaturated olefin compounds into a mixture of saturated alkane compounds including 243fa, 244fa and 245fa; (c) isolating and purifying the 245fa from the mixture of saturated alkane compounds; (d) dehydrochlorinating the 243fa and 244fa in the mixture of saturated alkane compounds to form 1233zd and 1234ze, respectively, and (e) isolating and purifying the trans-1234ze and trans-1233zd products generated in step (d).
