Abstract
PROCEDIMIENTO PARA LA OBTENCION DE DIISOCIANATOS DE FORMULA (I) Y DE MEZCLAS DE LOS MISMOS; DE MEZCLAS DE ESTOS CON HASTA UN 40 POR 100 DE DIISOCIANATOS DE FORMULA (II), Y DE MEZCLAS CON HASTA UN 30 POR 100 DE OTROS DIISOCIANATODIFENILMETANO-ISOMEROS, EN CASO DADO SUSTITUIDOS POR METILO. EN LAS FORMULAS (I) Y (II), R1, R2 Y R3 SON HIDROGENO O RADICAL METILO, PERO SIEMPRE EN CADA FORMULA DOS DE ELLOS SON HIDROGENO. EL PROCEDIMIENTO CONSISTE EN UNA REACCION DE FRIEDEL-CRAFTS DE UN HALURO DE 4-NITROBENCILO CON NITROBENCENO Y/O O-NITROTOLUENO Y/O P-NITROTOLUENO A COMPUESTOS DINITRO DE FORMULA (III). DESPUES DE SEPARAR EL CATALIZADOR SE REDUCEN LOS GRUPOS, OBTENIENDOSE LOS CORRESPONDIENTES COMPUESTOS DIAMINO AROMATICOS, QUE MEDIANTE FOSGENACION SE TRANSFORMAN EN LOS DIISOCIANATOS. ESTOS COMPUESTOS SE UTILIZAN EN LA FABRICACION DE MATERIALES SINTETICOS DE POLIURETANO.
