Abstract

produçãode (met) acroleína ou ácido (met) acrílico. um processo e um aparelho para produção de (met) acroleína ou ácido (met)acrílico por oxidação catalítica em fase gasosa, nos quais a temperatura de um veículo térmico pode ser controlada uniformemente, pontos quentes podem ser efetivamente diminuídos, e o manuseio é fácil. o processo compreende a oxidação catalítica de propano, propileno, isobutileno ou (met)acroleína com um gás contendo oxigênio molecular em uma fase vapor, usando um sal inorgânico como um veículo térmico para controle da temperatura de reação. o processo e o aparelho para produção de (met)acroleína ou ácido (met)acrílico é caracterizado pelo tato de que um alimentador de veículo térmico é empregado, que tem disposta nele uma válvula de controle, para controlar as taxas de alimentação e circulação de veículo térmico e na qual o elemento de gaxeta moído, vedando deslizantemente ambas a parte corpo da válvula de controle e um eixo rotativo encaixado na parte corpo, é feito de um material à base de mica.
