Abstract

UN PROCESO PARA LA COPRODUCCION DE DOS O MAS HIDROFLUOROALCANOS QUE COMPRENDE CONTACTAR UN ALQUENO O UN ALCANO HALOGENADO CON FLUORURO DE HIDROGENO A TEMPERATURA ELEVADA EN LA PRESENCIA DE UN CATALIZADOR DE FLUORINACION PARA PRODUCIR UN PRIMER HIDROFLUOROALCANO Y EN DONDE ESTA PROVISTO UN PRECURSOR ORGANICO A UN SEGUNDO HIDROFLUOROALCANO EN EL PROCESO POR EL CUAL PRODUCIR UN SEGUNDO HIDROFLUOROALCANO EN ADICCION AL PRIMER HIDROFLUOROALCANO. EN CASOS PREFERIDOS PARTICULARMENTE DEL PROCESO, EL PRIMER HIDROFLUOROALCANO ES 1,1,1,2 TETRAFLUOROETANO DERIVADO DE 2,2,2-CLORO-1 TRIFLUOROETANO O TRICLOROETILENO Y EL SEGUNDO HIDROFLUOROALCANO ES UNO O MAS DE PENTAFLUOROETANO, DIFLUOROMETANO Y 1,1,2,2TETRAFLUOROETANO.
