Abstract

SE PRESENTA UN METODO PARA LA PRODUCCION DE OXINDOLAS, QUE SE COMPONE DE LA FASES DE REACCIONAR UN ACIDO 2HALOGENOFENILIACETICO O SU SAL CON AMONIACO EN PRESENCIA DE UN CATALIZADOR DE UNA SAL DE COBRE, Y CALENTAR UNA MEZCLA DEL ACIDO 2-AMINOFENILIACETICO O SU SAL Y OXINDOLAS EN PRESENCIA DE UN CATALIZADOR ACIDO, SOMETER EL ACIDO 2-AMINOFENILACETICO O SU SAL A UNA REACCION DE CIERRE DE NUCLEOS. SEGUN ESTE METODO, ACIDOS 2-HALOGENOFENILACETICOS DE LOS QUE SE PUEDE DISPONER FACILMENTE SE UTILIZAN COMO MATERIA PRIMA INICIADORA PARA PRODUCIR DE FORMA INDUSTRIAL OXINDOLAS DE ELEVADA PUREZA EN ELEVADA CANTIDAD, EN UN SOLO RECIPIENTE SIN NECESIDAD DE LLEVAR A CABO PROCESOS COMPLICADOS. ADEMAS, PUESTO QUE LA AMINACION SE LLEVA A CABO A UNA TEMPERATURA MUY INFERIOR A LA UTILIZADA HABITUALMENTE, LA REDUCCION DEL PH DEL LIQUIDO OBTENIDO PUEDE SUPRIMIRSE. POR LO TANTO, LAS RESTRICCIONES EN LAS ESPECIFICACIONES DEL APARATO DE REACCION, COMO LA PREVENCION DE LA CORROSION Y LA RESISTENCIA A LA PRESION, PUEDEN MITIGARSE.
