摘要:
Provided are azeotropic and azeotrope-like compositions of 2,3-dichloro-3,3-difluoropropene (HCFO-1232xf) and hydrogen fluoride (HF). Such azeotropic and azeotrope-like compositions are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf)
摘要:
An azeotrope-like composition consisting essentially of 1,1,2,3-tetrachloropropene and hydrogen fluoride is provided, as well as methods that involve such an azeotrope-like composition.
摘要:
The invention provides a method for separating halocarbons. In particular, a method for separating 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) from 2-chloro-3,3,3-trifluoropropene (HCFC-1233xf) by adding a third component and then separating via conventional distillation. More particularly the invention pertains to a method for separating HCFC-244bb from HCFC-1233xf which are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf).
