Abstract
PROCEDIMIENTO DE OBTENCION DE BENZOXAZOLONA. CONSISTE EN CALENTAR ORTOCLOROFENOL BAJO PRESION DE AMONIACO, AÑADIENDO A CONTINUACION UREA A LA MEZCLA. EL CONJUNTO SE CALIENTA A PRESION ATMOSFERICA. LA PRESION EN LA PRIMERA ETAPA ESTA COMPRENDIDA ENTRE 1 Y 60 BARES. LA PRESION PARCIAL DE AMONIACO DE LA ATMOSFERA QUE CUBRE EL MEDIO DE REACCION DURANTE LA PRIMERA ETAPA ES SUPERIOR AL 50 POR 100 DE LA PRESION TOTAL. LA PROPORCION MOLAR DE UREA EMPLEADA CON RELACION AL ORTOCLOROFENOL ESTA COMPRENDIDA ENTRE 1 Y 15. LA TEMPERATURA DEL MEDIO DE REACCION EN LA PRIMERA ETAPA ESTA COMPRENDIDA ENTRE 100G Y 220GC. SE EMPLEA CLORURO CUPROSO COMO CATALIZADOR. A
