Abstract

PROCEDIMIENTO DE SEPARACION DE BISPENTAERITRITOMONFORMAL A PARTIR DE PENTAERITRITA BRUTA. CONSISTE EN SOMETER A LA PENTAERITRITA A UN TRATAMIENTO A TEMPERATURAS COMPRENDIDAS ENTRE 160 Y 200 C, EN UNSECADOR DE TAMBOR O DE REJILLA, EN UN TIEMPO COMPRENDIDO ENTRE QUINCE Y SESENTA MINUTOS, A UNA PRESION NORMAL, CON LO QUE SE ELIMINAN LASIMPUREZAS DE BISPENTAERITRITOMONOFORMAL Y SE MODIFICA EL TAMAÑO DE GRANOS DE LA PENTAERITRITA, REDUCIENDOSE LA PORCION DE GRANO FINO Y AUMENTADO LA DE GRANO GRUSO. EL CONTENIDO FINAL DE BISPENTAERITRITOMONOFORMAL ES INFERIOR AL 0,1 POR 100.
