Abstract
SE PREPARAN ISOCIANATOS MEDIANTE UN PROCESO CONTINUO DE REACCION DE LAS CORRESPONDIENTES AMINAS PRIMARIAS CON FOSGENO EN PRESENCIA DE UN ISOCIANATO COMO DISOLVENTE, HACIENDO REACCIONAR LA AMINA PRIMARIA, QUE PUEDE ESTAR DISUELTA EN UN DISOLVENTE ORGANICO E INERTE, CON FOSGENO, QUE ESTA DISUELTO EN EL ISOCIANATO, A TEMPERATURAS DE 60 A 150 (10{SUP,5} A 3.10{SUP,6}PA) PARA OBTENER EL CORRESPONDIENTE ISOCIANATO, SIENDO LA RELACION MOLAR DEL FOSGENO CON LA AMINA UTILIZADA DE 4:1 HASTA 1:1, Y ESTANDO LIBRE DE SOLIDOS EL ISOCIANATO UTILIZADO COMO DISOLVENTE Y TENIENDO UN VALOR DE CLORO HIDROLIZABLE MENOR DE 2 %.
