Abstract
LA INVENCION TRATA DE UN PROCEDIMIENTO DE VARIAS ETAPAS PARA OBTENER SIN INTERRUPCION DIISOCIANATOS CICLOALIFATICOS LIBRES DE FOSGENO Y COMPRENDE: DESTILAR LA DIAMINA CICLOALIFATICA PARA OBTENER CICLOALQUILENOBISUREA, HACER REACCIONAR A LA CICLOALQUILENOBISUREA CON ALCOHOL EN UN REACTOR DE DESTILACION A PRESION, PARA FORMAR LOS CICLOALQUENOBISCARBAMATOS Y DISOCIAR TERMICAMENTE LOS CICLOALQUENOSBIS CARBAMATOS EN UNA COLUMNA DE DISOCIACION Y RECTIFICACION PARA OBTENER EL CICLOALQUILENODIISOCIANATO Y ALCOHOL LIQUIDO. EL PROCESO DE VARIAS ETAPAS MENCIONADO ANTERIORMENTE SE REALIZA SIN EMPLEAR DISOLVENTE.
