Abstract

"PROCESSO PARA A PRODUçãO DE éSTERES". A presente invenção refere-se a um processo para a produção de um éster que compreende reagir um ácido carboxílico e etileno na presença de um catalisador ácido em uma fase vapor, em que a concentração de olefina que tem 3 ou mais átomos de carbono nos materiais de partida é controlada até 10.000 ppm ou menos em termos da razão molar para o total da olefina e etileno. Pode ser notavelmente evitado o processamento da deterioração do catalisador e uma operação contínua e estável pode ser realizada durante um longo período de tempo.
