Abstract

Patente de Invenção: <B>"PROCESSO PARA PREPARAçãO E/OU PURIFICAçãO DE AMIDO áCIDO FENIL éSTER SULFONATOS"<D>. A presente invenção refere-se à um processo para a preparação de um sal purificado de 4-sulfofenil-[(1-oxialcanoil)amino]alcanoato. O processo compreende as etapas de: (a) fornecimento de uma fonte de 4-sulfofenil-[(1-oxialcanoil)amino]alcanoato; (b) mistura da fonte com um sistema de purificação baseado em água para formar uma mistura de purificação, o sistema de purificação baseado em água tendo água presente em uma razão de 4-sulfofenil-[(1-oxialcanoil)amino]alcanoato para água variando em uma faixa de cerca de 1:0,05 a cerca de 1:50, preferencialmente de cerca de 1:0,1 a cerca de 1:40; (c) separação de um sal purificado de 4-sulfofenil-[(1-oxialcanoil)amino]alcanoato da mistura de purificação; e (d) coleta do referido sal purificado de 4-sulfofenil-[(1-oxialcanoil)amino]alcanoato. Em formas de realização preferidas, a mistura de purificação inclui um auxiliar de processamento tais como álcool etílico, álcool propílico, álcool isopropílico, acetona e suas misturas.
