  • Hydrogen fluoride compositions
    Patent number: 6177058
    Abstract: The present invention provides compositions that are intimate mixtures of hydrogen fluoride and a polymer. The compositions of the invention are less hazardous and, therefore, more conveniently stored, transported, and handled in comparison to pure hydrogen fluoride. Further, the hydrogen fluoride may be readily recovered from the compositions of the invention for use.

  • Process for hydrogen fluoride separation
    Patent number: 5766483
    Abstract: A method for separating hydrogen fluoride from a chemical mixture is provided. In the process of the invention, hydrogen fluoride is separated from a chemical mixture containing hydrogen fluoride by contacting the chemical mixture with a hydrogen fluoride binder. The separated hydrogen fluoride may be recovered from the hydrogen fluoride binder.

  • Process for the manufacture of 1,1,1,2-tetrafluoroethane
    Patent number: 5654494
    Abstract: This invention relates to a process for producing 1,1,1,2-tetrafluoroethane (HFC-134a). The process reacts, 1,1,1-trifluoro-2-chloroethane (HCFC-133a) and hydrogen fluoride in a first reactor. The product resulting from the first reaction step is brought to a second reactor together with trichloroethylene and hydrogen fluoride. The second reaction is conducted at a higher temperature than the first reactor. Optionally, HCl is removed prior to removal of the crude HFC-134a product. Unreacted HCFC-133a, trichloroethylene and hydrogen fluoride may be recycled back to the first reactor.
