Abstract

UNA MEZCLA QUE CONTIENE FLUORURO DE HIDROGENO Y 1,1,1,3,3PENTAFLUOR-2,3-DICLOROPROPANO SE SOMETE A DESTILACION PARA FORMAR UNA COMPOSICION ACEOTROPICA DE 85% A 95% MOLES DE FLUORURO DE HIDROGENO Y DE 15 A 5% MOLES DE 1,1,1,3,3-PENTAFLUOR-2,3DICLOROPROPANO, Y LA COMPOSICION ACEOTROPICA ES SEPARADA DEL LIQUIDO PARA FORMAR UNA FASE LIQUIDA REBAJADA. A CONTINUACION, UNA COMPOSICION ACEOTROPICA ES EXTRAIDA DE LA FASE LIQUIDA REBAJADA MEDIANTE DESTILACION, OBTENIENDOSE 1,1,1,3,3-PENTAFLUOR2,3-DICLOROPROPANO. SE OBTIENE 1,1,1,3,3-PENTAFLUOR-2,3-DICLOROPROPANO, SIN LA FORMACION DE UNA SOLUCION ACUOSA DE ACIDO HIDROFLUORICO DILUIDO, SUSTANCIALMENTE LIBRE DE FLUORURO DE HIDROGENO.
