Abstract

CUANDO SE OBTIENE CLORURO DE VINILO POR DISOCIACION TERMICA DE 1,2-DICLOROETANO, SE OBTIENEN EN TRES ETAPAS DE DESTILACION PRIMERO ACIDO CLORHIDRICO, SEGUNDO CLORURO DE VINILO Y FINALMENTE ACIDO CLORHIDRICO Y CLORURO DE VINILO JUNTOS. SI EL AGUA QUE LLEGA AL FINAL NO SE SEPARA DEL RESIDUO, ES VUELTA A LA PRIMERA ETAPA CON EL PRODUCTO DE CABEZA Y ORIGINA CORROSIONES. SI QUITAMOS EL AGUA DE LA CABEZA DE LA TERCERA ETAPA DE DESTILACION, PREFERIBLEMENTE POR SECADO, SE EVITA LA CORROSION.
