Abstract
The present invention provides the novel chlorofluorohydrocarbon 1,1-difluoro-1,4-dichlorobutane, and a process for its preparation by reacting 1,1,1,4-tetrachlorobutane with hydrogen fluoride in the liquid phase. The product has useful solvent properties and is also useful in synthetic chemistry for the introduction of fluorocarbon functionality.
