Abstract

Patente de Invenção: "PRODUçãO DE FLUOROCARBONOS ALIFáTICOS". Processos para preparar vários fluorocarbonos são descritos. Os processos são descritos em que os rendimentos dos produtos desejados são aumentados por conversão sem fim de produtos indesejados em intermediários reativos. Trifluoroetileno é preparado em um rendimento maior que 50% por pirólise de 1-cloro-2,2,2- trifluoroetano a uma temperatura de cerca de 725 <198>C. 1,1,1,3,3- pentafluoropropileno é preparado por pirólise de 1-cloro-2,2,2- trifluoroetano na presença de clorodifluorometano. Trifluoroetileno é preparado por pirólise de 1,2,2,2-tetrafluoroetano. 1-cloro-2,2-difluoroetileno é preparado por pirólise de 1-cloro-2,2,2- trifluoroetano. 1,1- dicloro-2,2- difluoroetileno é preparado por pirólise de 1-cloro-2,2,2- tirfluoroetano na presença de clorodifluorometano e cloreto de hidrogênio. 1,1,1,2,3,4,4,4- octafluoro-2-buteno é preparado por pirólise de 1-cloro-1,2,2,2- tetrafluoroetano. 1,1,1,2,3,4,4,4- octafluoro-2-buteno é preparado por pirólise de 1,1,2,2,2-pentafluoroetano. 1,2,2,2- tetrafluoroetano é preparado por pirólise de 1,1,2,2,2- pentafluoroetano. 1,1-dicloro-1,2,2,2- tetrafluoroetano é preparado por pirólise de 1-cloro-1,2,2,2- tetrafluoroetano.
