Abstract
ELIMINACION DE SILANOS FUNCIONALES CONTENIDOS COMO IMPUREZAS EN LOS ORGANOSILANOS. LO QUE SE DESCRIBE ES UN PROCEDIMIENTO PARA EL TRATAMIENTO DE ORGANOSILANOS PARA REDUCIR EL CONTENIDO DE SILANOS DE LA MAS ALTA FUNCIONALIDAD. EL PROCEDIMIENTO COMPRENDE: (A) PONER EN CONTACTO UNA MEZCLA, INCLUYENDO ESTA UNA PORCION MAYOR DE ORGANOSILANO Y UNA PORCION MENOR DE SILANOS DE LA MAS ALTA FUNCIONALIDAD, CON ORGANOSILOXANOS, Y UNA CANTIDAD SUFICIENTE DE UN CATALIZADOR EFECTIVO EN LA PROMOCION DE LA REACCION ENTRE LOS SILANOS DE MAS ALTA FUNCIONALIDAD Y EL ORGANOSILOXANO PARA FORMAR SILOXANOS CON UNA POLIFUNCIONALIDAD HALOGENADA MAS ALTA; Y (B) AISLAR EL ORGANOSILANO DE LOS SILOXANOS POLIFUNCIONALES Y LOS ORGANOSILOXANOS POR MEDIOS CONVENCIONALES TALES COMO DESTILACION.
