Abstract

SE PRESENTA UN PROCESO PARA PREPARAR UN MDI LIQUIDO, QUE COMPRENDE LA ADICION, AL MDI, DE UN CATALIZADOR DE FOSFORINA Y UN ESTER DE ACIDO FOSFOROSO DE LA FORMULA I, O DE LA FORMULA II EN DONDE R1, R2, R3, R4, R5, R6 Y R7 SON IGUALES O DIFERENTES Y REPRESENTAN UN GRUPO DE ALQUILO C{SUB, 4-20}, Y LA CONDUCCION DE UNA REACCION. EFECTO: EL PROCESO DE ACUERDO CON LA INVENCION PUEDE PRODUCIR MDI LIQUIDO QUE TIENE PROPIEDADES ESTABLES. ESTE MDI LIQUIDO CASI NO SE DECOLORA, INCLUSO SI SE ALMACENA DURANTE UN LARGO PERIODO DE TIEMPO. EL PROCESO PUEDE SUMINISTRAR COMERCIALMENTE UN MATERIAL EN BRUTO DE POLIURETANO QUE TIENE UN FACIL MANEJO.
