<P>PROBLEM TO BE SOLVED: To provide a ternary azeotropic composition of 2-chloro-3,3,3-trifluoropropene, 2-chloro-1,1,1,2-tetrafluoropropane and hydrogen fluoride, and an azeotropic-mixture-like composition thereof. <P>SOLUTION: This azeotropic and the azeotrope-mixture-like compositions are comprises about 1-50 wt.% of hydrogen fluoride, and about 50-99 wt.% of organic portion comprising substantially a mixture of 2-chloro-3,3,3-trifluoropropene and 2-chloro-1,1,1,2-tetrafluoropropane (the 2-chloro-3,3,3-trifluoropropene is contained by an amount of about 50-90 wt.% in the organic portion, and the 2-chloro-1,1,1,2-tetrafluoropropane is contained by an amount of about 10-50 wt.% in the organic portion). The azeotropic and the azeotrope-mixture-like compositions are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf). <P>COPYRIGHT: (C)2010,JPO&INPIT |
