Abstract

PROCEDIMIENTO PARA LA PREPARACION DE DISOLUCIONES CONCENTRADAS DE CROMOGENOS. CONSISTE EN TRATAR LA DISOLUCION ORGANICA PROCEDENTE DEL PROCESO DE PRODUCCION DEL CROMOGENO DE MODO QUE SE DESHIDRATA, PARA LO CUAL SE UTILIZA AGUA CALIENTE A UNA TEMPERATURA DE 60 GRADOS C A 85 GRADOS C, ELIMINAR EL DISOLVENTE DE LA MASA REACCIONAL POR DESTILACION A VACIO Y RECOGER EL RESIGUO OLEOSO A UNA TEMPERATURA ENTRE 20 GRADOS C Y 100 GRADOS C EN UN DISOLVENTE HIDROFOBO, HASTA OBTENER UNA CONCENTRACION LIQUIDA MINIMA DE 10 POR 100. ESTAS DISOLUCIONES TIENEN APLICACION PARA LA OBTENCION DE UN MATERIAL DE REGISTRO SENSIBLE A LA PRESION.
