Abstract

N-ACETIL-PARA-AMINOFENOL SE PREPARA AL PONER EN CONTACTO OXIMA 4-HIDROXIACETOFENONA CON UN CATALIZADOR DE READAPTACION BECKMANN EN UN SOLVENTE DE REACCION ALCANOATO ALQUILO. SE DESCRIBE UN PROCESO INTEGRADO DONDE 4-HIDROXIACETOFENONA ES PUESTA EN REACCION CON UNA SAL HIDROXILANINA Y UNA BASE PARA OBTENER OXIMA 4-HIDROXIACETOFENONA, EL PRODUCTO DE OXIMA ES EXTRAIDO DESDE LA MEZCLA DE REACCION RESULTANTE CON UN SOLVENTE SUSTANCIALMENTE NO MISCIBLE EN AGUA Y LA MEZCLA DE OXIMA Y EL SOLVENTE SUSTANCIALMENTE NO MISCIBLE EN AGUA SE PONEN EN CONTACTO CON UN CATALIZADOR DE READAPTACION BECKMANN PARA PRODUCIR N-ACETIL-PARA -AMINOFENOL. SE UTILIZAN NUEVOS CATALIZADORES DE READAPTACION BECKMANN PARA LIMITAR LA FORMACION DE UN SUBPRODUCTO EN EL SOLVENTE ESTER.
