Abstract
"MéTODO PARA SEPARAçãO DE METIL MERCAPTANO DE MISTURAS DE GáS DE REAçãO". A presente invenção refere-se a um método para a separação de metil mercaptano de misturas de gás de reação obtidas por meio da conversão catalítica de H~ 2~S com metanol, por meio de conversão do metil mercaptano em MMP na presença de subprodutos com acroleína, e separação do mesmo.
