The invention relates to azeotropic and azeotrope-like mixtures of HFC-32, HCl, and Cl, and processes for separating the azeotrope-like mixtures of HFC-32 and HCL and HFC-32, HCL and Cl.

Azeotrope-like compositions of difluoromethane

The invention relates to azeotropic and azeotrope-like mixtures of HFC-32 and HCl or a mixture of HCl and Cl, and a process for separating the azeotrope-like mixtures.

Disclosed are improved fluorination processes and fluorine-containing compositions which involve introducing to one or more fluorination process compositions a water reactive agent in an amount and under conditions effective to decrease the amount of water in that composition. The water reactive agent is preferably introduced to the fluorination reaction process at a location proximate to the site of the fluorination reaction, or upstream of the fluorination reaction, in amounts and under conditions effective to produce a relatively lower concentration of water in the composition, and preferably throughout the fluorination process.
