Abstract

LA INVENCION SE OCUPA DE UN PROCESO PARA LA RECUPERACION DE POLIOLES SECUNDARIOS A PARTIR DE CONCENTRADOS DE POLIADUCTOS, QUE CONTIENEN SUSTANCIAS DE ACOMPAÑAMIENTO NO GLICOSIDABLES. PARA ELLO SE TRATA EL CONCENTRADO DE POLIADUCTO PREVIAMENTE DESMENUZADO BAJO ADICION DE GLICOL O GLICOLES EN UN REACTOR DE CORTE CON TEMPERATURA ELEVADA Y PRESION PERO CON TIEMPO DE PERMANENCIA RELATIVAMENTE REDUCIDO. LOS COMPONENTES NO GLICOSIDABLES SON ADEMAS DESMENUZADOS Y DISPERSADOS Y LOS POLIADUCTOS SON GLICOSILADOS PREVIAMENTE. EL PRODUCTO PREVIO ASI OBTENIDO SE TRATA EN UN REACTOR O REACTORES DE AGITACION COLOCADOS A CONTINUACION EN UN NIVEL DE TEMPERATURA ALGO ELEVADO Y DURANTE EL TIEMPO DE TRATAMIENTO LARGOS Y A CONTINUACION BAJO OTRA ADICION DE GLICOL. A PARTIR DEL POLIOL SECUNDARIO OBTENIDO FINALMENTE PUEDE GENERARSE UN PLASTICO, QUE PUEDE SER ELABORADO POSTERIORMENTE PARA LA OBTENCION DE UN NUEVO COMPONENTE DE PLASTICO.
