Abstract: Two methods for reducing CFC impurities and, in particular, CFC-114, in the HFO-1234ze(E) production process from the reaction of CFC-113 and HF. The first method involves subjecting an intermediate or recycle stream to separation and distillation to purge CFC-113 from the process. The second method involves operating the separation at a higher pressure avoids the formation of an azeotrope between CFC-113 and HFC-245fa. The CFC-113/HFC245fa azeotrope is discussed, as well as other optional processes for removal or mitigation of CFC-113 which include further separations that remove CFC-114 from the HFO-1234ze(E) product and/or CFC-113 from the HFC-245fa feed to produce an HFO-1234ze(E) product that is largely free from CFC-114 and other CFC impurities.
