Abstract:
The present invention relates to a process for preparation of olefins containing fluorine.

Claim (Index 14):
The process of  claim 10  comprising:\n a) providing a mixture of methyl chloride and chlorodifluoromethane, said mixture is either premixed or added separately; \n b) providing and contacting heat medium with step a) mixture to form second mixture comprising 2,3,3,3-tetrafluoropropene, methyl chloride and fluorinated compounds having boiling point in the range of \u221214 to \u221290\u00b0 C.; \n c) drying the second mixture of step b) to obtain anhydrous second mixture; \n d) subjecting the anhydrous second mixture of step c) to distillation to obtain anhydrous third mixture comprising methane, trifluoromethane, chlorotrifluoroethene, chlorodifluoromethane, tetrafluoroethyelene, vinylidene fluoride and difluoromethane and anhydrous fourth mixture comprising 2,3,3,3-tetrafluoropropene, methyl chloride, octafluorocyclobutane, chlorotrifluoroethyelene and tetrafluorochloroethane; \n e) contacting the anhydrous third mixture of step d) with molecular sieve of size 3 \u212b to 5 \u212b to obtain a fifth mixture, said mixture is free of difluoromethane and is recycled; \n f) subjecting the anhydrous fourth mixture of step d) to distillation to obtain anhydrous sixth mixture comprising 2,3,3,3-tetrafluoropropene and methyl chloride; \n g) optionally, purifying the anhydrous sixth mixture by contacting with solvent in a solvent scrubber; \n h) contacting the anhydrous sixth mixture of step f) or step g) with molecular sieve of size 3 \u212b to 5 \u212b to obtain seventh mixture, said mixture is free of methyl chloride; and \n i) isolating 2,3,3,3-tetrafluoropropene from the seventh mixture of step h).
