Abstract
PROCEDIMIENTO PARA LA OBTENCION DE POLIORGANOSILOXANOS SILICIOFUNCIONALES, VARIAS VECES RAMIFICADOS, CONTENIENDO ACILOXI Y CLORO, MIXTOS, EQUILIBRADOS. SE MEZCLA UN CLOROSILANO DE FORMULA RASICL4-A, EN LA QUE A ES 0 O 1, CON UNO O VARIOS ORGANOSILOXANOS; SE AÑADE UN CATALIZADOR Y SE CALIENTA BAJO AGITACION HASTA 60GC. SE AÑADE EL 5 POR 100 DE LA CANTIDAD TOTAL NECESARIA DE ACIDO CARBOXILICO MONOBASICO, AL MENOS 11 VECES LA CANTIDAD MOLAR EQUIVALENTE A LOS ATOMOS DEL CLORO LIGADOS AL SILICIO, SE CALIENTA A 90GC, SE AÑADE HASTA EL 50 POR 100 DEL ACIDO CARBOXILICO NECESARIO Y SE CALIENTA A UNOS 135GC. SE AGREGA A ESTA TEMPERATURA EL RESTO DEL ACIDO CARBOXILICO, PREVIAMENTE MEZCLADO CON LA CANTIDAD DE AGUA CALCULADA PARA LOGRAR LA MULTIPLE RAMIFICACION DESEADA. SE HIERVE A REFLUJO DURANTE 1-2 HORAS Y SE SEPARA POR DESTILACION A VACIO EL EXCESO DE ACIDO CARBOXILICO. A
