Preparation of CCl.sub.3 F and CCl.sub.2 F.sub.2 from fluorspar and CCl. sub.4

摘要

Preparation of CCl.sub.3 F and CCl.sub.2 F.sub.2 by countercurrently contacting CaF.sub.2 and CCl.sub.4 under reaction conditions to provide high conversion both of CCl.sub.4 to fluorine- containing products and CaF. sub.2 to CaCl.sub.2.
