Abstract
PROCEDIMIENTO PARA LA PREPARACION DE DIISOCIANATOS POR REACCION DE ALCOHOLES BIVALENTES O DE NITROFENOXALCANOLES CON NITROCLOROBENCENO O LOS CORRESPOENDIENTES DINITROCOMPUESTOS, TRANSFORMACION DE ESTOS DINITROCOMPUESTOS EN LAS DIAMINAS CORRESPONDIENTES Y FOSGENACION FINAL DE ESTAS. LA REACCION SE EFECTUA EN PRESENCIA DE DISOLVENTES APROTICOS FUERTEMENTE POLARES Y EN PRESENICA DE HIDROXIDO DE SODIO Y/O HIDROXIDO DE POTASIO, QUE SUMINISTRAN, SEGUN ESTE PROCEDIMIENTO EN PRIMER LUGAR LOS DIISOCIANATOS OBTENIDOS QUE ENCUENTRAN APLICACION COMO PIEZAS COMPONENTES EN LA OBTENCION DE PLASTICOS DE POLIURETANO.
