Abstract

"PROCESSO PARA A PRODUçãO DE áCIDO CARBOXìLICO OU SEU éSTER". Trata-se de um processo para a produção de um ácido carboxílico ou seu éster através da oxidação de fase líquida catalítica de um precursor correspondente em ácido acético como solvente, sendo que o dito processo compreende: (i) a formação de um meio da reação que compreende ácido acético, um catalisador de oxidação, um precursor e um oxidante; (ii) opcionalmente, a reciclagem do acetato de metila produzido a partir de ácido acético como um subproduto de volta meio da reação; (iii) a introdução de acetato de metila e/ou metanol adicionais ao meio da reação, sendo que os ditos acetato de metila e/ou metanol adicionais são adicionais a algum acetato de metila recuperado reciclado de volta ao meio da reação.
