Process for separating hydrogen fluoride from its mixtures with 1,1,1-trifluoro-2-chloroethane

Separation of hydrogen fluoride (HF) from its mixtures with 1,1,1-trifluoro-2-chloroethane (F133a). By settling the mixture of HF and F133a at a temperature below 0 DEG C, there is obtained a lower organic phase which is poor in HF and an upper phase which is rich in HF. The latter can be directly r...
