Abstract

"PROCESSOS PARA A PRODUçãO DE áCIDO CARBOXìLICO OU SEU éSTER E PROCESSO PARA A OXIDAçãO DE FASE LìQUIDA CATALìTICA DO PARAXILENO". Processo aprimorado para a produção de ácidos carboxílicos ou seus ésteres, por oxidação de fase líquida catalítica de um precursor correspondente em um solvente apropriado, que compreende alimentar os reagentes a uma primeira zona reacional de oxidação, com uma proporção de alta de solvente e alta pressão, onde a captação de oxigênio é limitada a menos de 50% do oxigênio necessário, para a completa conversão do precursor em seu ácido carboxílico correspondente, e então alimentar o meio reacional resultante para a segunda zona reacional de oxidação.
