Abstract
PROCEDIMIENTO PARA LA PURIFICACION DE HEXAMETILDISILOXANO. SE PARTE DE UNA MEZCLA DE HEXAMETILDISILOXANO Y ACETONITRICO DE LA QUE SE SEPARA POR DESTILACION CONTINUA O DISCONTINUAMENTE HEXAMETILDISILOXANO EN FORMA DE AZEOTRONO CON ACETONITRILO; A PARTIR DE ESTE ATEOTRONO SE SEPARA LA FASE MAS LIGERA Y DESPUES DE EFECTUAR LA SEPARACION A PARTIR DE EL, SE OBTIENE EL HEXAMETILDISILOXANO TRAS SEPARACION POR DESTILACION. LA FASE MAS PESADA DEL AZEOTROPO, SE UTILIZA COMO UNA DE LAS SUSTANCIAS DE PARTIDA PARA LA FORMACION DEL AZEOTROPO DE HEXAMETILDISILOXANOÑACETONITRILO.
