Abstract

PROCESSO PARA A PRODUçãO CONTìNUA DE METILMERCAPTANO. A presente invenção refere-se a um processo para a produção contínua de metilmercaptano através da reação de uma mistura gasosa de produto de partida de metanol e ácido sulfídrico na fase gasosa a uma temperatura de reação entre 200 e 600°C e com uma pressão de funcionamento de 150 até 4000 KPa (1,5 até 40 bar) em um catalisador em um reator de vários leitos.
