Abstract

"PROCESSO PARA ESTERIFICAR áCIDO (MET)ACRìLICO COM UM ALCANOL". Em um processo para esterificar ácido (met)acrílico com um alcanol na presença de um catalisador de esterificação, em que compostos iniciais não-convertidos e éster (met)acrílico a ser formado são separados por destilação e um produto de fundo contendo oxiéster é formado, o produto de fundo é primeiramente separado e, depois, os oxiésteres contidos no mesmo são clivados na presença de um ácido alquilbenzenossulfónico de cadeia relativamente longa a temperaturas elevadas.
