Abstract

PARA ELIMINAR LAS HUELLAS DE CLOROFLUOROMETANO PRESENTES EN UN DIFLUOROMETANO, SE HACE PASAR EL DIFLUOROMETANO A PURIFICAR SOBRE UN TAMIZ MOLECULAR 13X A UNA TEMPERATURA AL MENOS IGUAL A 60 (GRADOS) C. EL TAMIZ PUEDE REGENERARSE POR LAVADO MEDIANTE UNA SOLUCION DE CARBONATO DE SODIO O DE POTASIO Y CALENTAMIENTO A TEMPERATURA ELEVADA BAJO ATMOSFERA INERTE O AL VACIO.
