Abstract

SE PROVEE UN PROCESO PARA OBTENER ESTERES DE ACIDO CARBONICO FOSFORO SUSTITUIDOS O SULFOFENILO DE AMONIO CUATERNARIO. EL PASO IMPORTANTE EN ESTE PROCESO INCLUYE REACCIONAR UN FENILO AMONIO CUATERNARIO O ESTER DE ACIDO CARBONICO FOSFORO SUSTITUIDO CON ACEITE QUE CONTIENE DE 0,5 A 33% DE TRIOXIDO DE AZUFRE. CANTIDADES EXCEDIENDO EL 33% DE TRIOXIDO DE AZUFRE CONDUCEN A INCREMENTAR EL TIEMPO DE REACCION Y, EVENTUALMENTE, A CONVERSIONES DE PRODUCTOS INACEPTABLES.
