Abstract
"PROCESSO PARA PRODUçãO DE COMPOSTO DE áCIDO (MET)ACRìLICO". A presente invenção refere-se a processo para produção de (met)acroleína ou ácido (met)acrílico por oxidação catalítica em fase vapor de propileno, propano ou isobutileno num reator de oxidação, caracterizado pelo fato da matéria-prima de gás misto introduzida no reator de oxidação ser ajustada para ter uma temperatura maior do que o ponto de orvalho do gás misto. O processo evita a variação da composição da matéria-prima de gás misto, a elevação anormal de temperatura do reator de oxidação e a redução da atividade do catalisador e da vida do catalisador, que acarreta a produção de ácido (met)acrílico e um derivado dele com estabilidade e boa eficiência.
