ABSTRACT:
A process is disclosed for the liquid phase separation and recovery of hydrogen fluoride from a mixture comprising hydrogen fluoride and a fluorinated organic hydrocarbon. The process requires that the mixture be treated with a sufficient amount of a coupled phase-separating agent comprising an organic or inorganic salt, an alkanolamine or mixtures thereof and a substituted or unsubstituted aromatic compound to form a first and a second phase. The first phase that is formed is a hydrogen fluoride-rich phase that additionally contains substantially all of said salt, said alkanolamine or mixtures thereof from the coupled phase-separating agent. The second phase comprises substantially all of said aromatic compound and the fluorinated organic hydrocarbon. It is substantially free of hydrogen fluoride. The phases are separated from each other. Hydrogen fluoride and the salt, alkanolamine or mixtures thereof are then recovered from the separated first phase and the aromatic compound and fluorinated organic hydrocarbon are recovered from the separated second phase.
