主权项 1. A process for making the compound 1,1,2-trichloro-3,3,3-trifluoropropane (233da) from 1,1,1,2,3,3-hexachloropropane comprising the steps: (a) fluorinating a metal catalyst consisting of SbCl5; and (b) fluorinating 1,1,1,2,3,3-hexachloropropane in the presence of the fluorinated metal catalyst at a reaction temperature in the range of 90° C. to 100° C. for a time period in the range of 6 to 20 hours, to produce a reaction mixture containing up to about 35% by weight of 1,1,2-trichloro-3,3,3-trifluoropropane.
