Abstract

"PROCESSO PARA A REMOçãO DE FORMIATO DE TRIALQUILAMÈNIO A PARTIR DE METILOLALCANOS". Processo para a remoção de formiato de trialquilamónio a partir de metilolalcanos, que podem ser obtidos através de condensação de formaldeído com um aldeido superior, em que o formiato de trialquilamónio é decomposto, em alta temperatura, através de catalisadores que contêm pelo menos um metal dos grupos 8 a 12 da Tabela Periódica, na presença de um gás contendo hidrogênio. O processo possibilita a separação do formiato de trialquilamónio após o processo Cannizzaro orgânico, como também a preparação de metilolalcanos de acordo com o processo de hidrogenação.
