Abstract

Organic fluorine compounds are obtained by passing a mixture of a halo-olefine and hydrogen fluoride in the gaseous phase at elevated temperature, e.g. 200-400 DEG C., over a catalyst consisting essentially of partially fluorinated activated alumina, which may be activated by impregnation with a solution of one or more polyvalent metal halides, e.g. halides of chromium, cobalt, nickel or manganese. In examples (1) CHCl:CCl2 gives CF3CH2Cl; (2) vinyl chloride gives CH3CHF2, CH2:CHF and CH3CHFCl; (3) CH2:CCl2 gives CH3CF3; and (4) CCl2:CCl2 gives CF3CHCl2. Other products are also obtained in small amounts. Other specified reactions are of CCl2:CHCH3 to CH3CH2CF3, and of CH2:CCl.CH2Cl to CH2ClCF2CH3, through various intermediates. Reference has been directed by the Comptroller to Specification 770,640.ALSO:Fluorination catalysts (see Division C2) consist of partially fluorinated activated alumina, e.g. activated by impregnation with a solution of one or more polyvalent metal halides, such as halides of chromium, cobalt, nickel or manganese. Alumina may be impregnated with a solution as defined, heated in air at 500-650 DEG C., and then treated with HF at 250-300 DEG C., preferably to 70-80% fluorination of the alumina. The catalyst may form a fixed, mobile or fluid bed. Used catalyst may be regenerated by treatment with air and steam at 500-700 DEG C. Reference has been directed by the Comptroller to Specification 770,640.
