Abstract

PROCESSO DE PRODUçãO DE áCIDO CARBOXìLICO HETEROAROMáTICO Processo de produção de ácido carboxílico heteroaromático que compreende o contato na presença de catalisador de precursor do mencionado ácido carboxílico com oxidante, em que esse contato é efetuado com o mencionado precursor e o oxidante em solvente aquoso que compreende água sob condições supercríticas ou perto de condições supercríticas, próximo ao ponto supercrítico.HETEROAROMATIC CARBOXYLIC ACID PRODUCTION PROCESS Heteroaromatic carboxylic acid production process comprising contact in the presence of precursor catalyst of said carboxylic acid with oxidant, wherein such contact is effected with said precursor and the oxidant in aqueous solvent comprising water. under supercritical conditions or near supercritical conditions, near the supercritical point.
