摘要：
The present disclosure provides a novel azeotropic or azeotrope-like composition comprising hydrogen fluoride and 1,1,2-trifluoroethane (HFC-143), 1-chloro-2, 2-difluoroethane (HCFC-142), or 1,2-dichloro-1-fluoroethane (HCFC-141); and a separation method using the composition.
An azeotropic or azeotrope-like composition comprising hydrogen fluoride and HFC-143. An azeotropic or azeotrope-like composition comprising hydrogen fluoride and HCFC-142. An azeotropic or azeotrope-like composition comprising hydrogen fluoride and HCFC-141. A separation method of a composition comprising hydrogen fluoride and at least one member selected from the group consisting of HFC-143, HCFC-142, and HCFC-141.
