Abstract
Provided is a method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene where (E)-1-chloro-2,3,3-trifluoro-1-propene and water can be efficiently removed and (Z)-1-chloro-2,3,3-trifluoro-1-propene with higher purity can be obtained at a higher recovery ratio. The method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene includes: distilling a distillation composition which contains (Z)-1-chloro-2,3,3-trifluoro-1-propene, (E)-1-chloro-2,3,3-trifluoro-1-propene and water to remove (E)-1-chloro-2,3,3-trifluoro-1-propene and water as an azeotropic composition or an azeotropic-like composition.
Claims6
A method for producing (Z)-1-chloro-2,3,3-trifluoro-1-propene, comprising:
- preparing a distillation composition which contains (Z)-1-chloro-2,3,3-trifluoro-1-propene, (E)-1-chloro-2,3,3-trifluoro-1-propene and water;
- and
- distilling the distillation composition to remove (E)-1-chloro-2,3,3-trifluoro-1-propene and water from the distillation composition as an azeotropic composition or an azeotropic-like composition.
