Abstract

UN PROCEDIMIENTO PARA LA PREPARACION DE UN CIANATO AROMATICO. COMPRENDE: A) PREPARAR IN SITU UN CLORURO DE CIANOGENO MEDIANTE PUESTA EN CONTACTO DE UNA SOLUCION DE CLORO EN UN HIDROCARBURO CLORADO CON UNA SOLUCION ACUOSA DE UN CIANURO DE METAL ALCALINO A UNA TEMPERATURA DE 0JC O INFERIOR BAJO CONDICIONES TALES QUE SE PREPARA CLORURO DE CIANOGENO; Y B) PONER EN CONTACTO EL CLORURO DE CIANOGENO DISUELTO EN EL HIDROCARBURO CLORADO CON UN COMPUESTO AROMATICO HIDROXI-SUSTITUIDO DISUELTO EN UN HIDROCARBURO CLORADO, UN ALCOHOL SECUNDARIO O UN ALCOHOL TERCIARIO, EN PRESENCIA DE UNA AMINA TERCIARIA A UNA TEMPERATURA DE UNOS 9JC O INFERIOR BAJO CONDICIONES TALES QUE SE PREPARA UN POLI(CIANATO AROMATICO). EN LA OPERACION A) SE SEPARA EL HIDROCARBURO CLORADO, EN EL QUE ESTA DISUELTO EL CLORURO DE CIANOGENO, DE LA CAPA ACUOSA, EN LA QUE ESTA DISUELTA UNA SAL CLORURO DE METAL ALCALINO.
