Abstract

ELIMINACION DE LOS HIDROCARBUROS CLORADOS DE ALQUILSILANOS. SE DESCRIBE UN PROCEDIMIENTO PARA REDUCIR EL CONTENIDO DE CLOROCARBUROS EN ALQUILSILANOS. EL PROCEDIMIENTO COMPRENDE: (A) PONER EN CONTACTO ALQUILSILANOS BRUTOS, QUE CONTIENEN UNA PORCION MINORITARIA DE CLOROCARBUROS Y UN SILANO QUE CONTIENE HIDROGENO CON UN CATALIZADOR, DONDE EL CATALIZADOR ES UNA CANTIDAD SUFICIENTE DE UN MATERIAL FORMADOR DE UN ACIDO DE LEWIS EFECTIVO; (B) FACILITAR LA REACCION DE LOS CLOROCARBUROS CON EL SILANO QUE CONTIENE HIDROGENO EN CONTACTO CON EL CATALIZADOR PARA CONVERTIR LOS CLOROCARBUROS EN ALCANOS LINEALES O RAMIFICADOS; (C) SEPARAR EL CATALIZADOR DE LOS ALQUILSILANOS Y ALCANOS; Y (D) RECUPERAR LOS ALQUILSILANOS CON UN CONTENIDO MAS BAJO EN CLOROCARBUROS.
