摘要:
The present invention pertains to azeotropic and azeotrope-like compositions of the following three blends: 1. Trans-1,3,3,3-tetrafluoropropene (HFO-1234ze(E)), cis-1,3,3,3-tetrafluoropropene (HFO-1234ze(Z)) and hydrogen fluoride (HF); 2. HFO-1234ze(E), 1,1,1,3,3-pentafluoropropane (HFC-245fa) and HF; and 3. HFO-1234ze(Z), HFC-245fa and HF. These azeotropic and azeotrope-like compositions are useful as intermediates in the production of HFO-1234ze(E).
