Abstract
processo para a coprodução de metil mercaptana e de dissulfeto de dimetila a partir de óxidos de carbono. a invenção refere-se a um processo para a coprodução de metil mercaptana e de dissulfeto de dimetila, compreendendo as seguintes etapas sucessivas: a) reação de pelo menos um óxido de carbono na presença de sulfeto de hidrogênio (h2s) e hidrogênio para formar uma corrente (m) compreendendo metil mercaptana, água e possivelmente sulfeto de hidrogênio não reagido, b) purificação da corrente (m) para se obter uma corrente (n) enriquecida em metil mercaptana e uma corrente contendo os compostos não condensáveis (mnão cond), c) reciclagem opcional da corrente de compostos não condensáveis (mnão cond) obtidas a partir da etapa b) dentro da etapa a), d) recuperação de uma primeira porção da corrente (n) incluindo metil mercaptana purificada na etapa b), e) oxidação com enxofre da segunda porção da corrente (n) de metil mercaptana, para formar uma corrente (o) compreendendo dissulfeto de dimetila, sulfeto de hidrogênio e possivelmente metil mercaptana não reagida, f) purificação da corrente (o) para separar, por um lado, o dissulfeto de dimetila enriquecido e, por outro lado, o sulfeto de hidrogênio e possivelmente a metil mercaptana que não reagiu na etapa e), g) reciclagem do sulfeto de hidrogênio e possivelmente da metil mercaptana isolada na etapa f) na corrente (m) obtida a partir da etapa a), h) recuperação do dissulfeto de dimetila isolado na etapa f).
