Abstract
abstract a process for producing dimethyl sulfoxide, wherein said process comprises the following steps: (1) contacting hydrogen sulfide with methanol to produce a mixture containing dimethyl sulfide, and separating dimethyl sulfide from the mixture; and (2) in the presence or absence of a solvent, contacting dimethyl sulfide obtained in step (1) with at least one oxidant and a catalyst to produce a mixture containing dimethyl sulfoxide, said catalyst comprises at least one ti-si molecular sieve. tradução do resumo resumo patente de invenção: "método de preparação de sulfóxido de dimetila". é fornecido um método de preparação de sulfóxido de dimetila, o método compreendendo as seguintes etapas: 1) colocar o sulfeto de hidrogênio em contato com metanol para se obter uma mistura contendo sulfeto de dimetila, e separar o sulfeto de dimetila da mistura; 2) na presença ou ausência de um solvente, colocar o sulfeto de dimetila obtido na etapa 1) em contato com pelo menos um oxidante e um catalisador para se obter uma mistura contendo o sulfóxido de dimetila, o catalisador contendo pelo menos uma peneira molecular de silício de titânio. o método da presente invenção possui uma taxa elevada de conversão de sulfeto de dimetila, uma taxa eficaz de utilização de oxidante, e boa seletividade de sulfóxido de dimetila. o método da presente invenção utiliza a peneira molecular de silício de titânio como o catalisador, o que permite a separação fácil do produto. além disso, o método da presente invenção possui uma condição de reação suave e facilmente controlável, sendo assim particularmente adequado para a produção em grande escala. 1/1
