    摘要: The present invention relates to a method for preparing methyl mercaptan, in batches or continuously, preferably continuously, said method including at least the following steps: a) reacting at least one hydrocarbon feedstock in the presence of hydrogen sulphide (H
    2 S) and optionally sulphur (S) such as to form carbon disulphide (CS
    2 ) and hydrogen (H
    2 ); b) reacting said carbon disulphide (CS
    2 ) by hydrogenation in the presence of said hydrogen (H2) obtained in step a) such as to form methyl mercaptan (CH
    3 SH), hydrogen sulphide (H
    2 S) and possibly hydrogen (H
    2 ); c) optionally recirculating said hydrogen sulphide (H
    2 S) formed during step b) to step a); and d) recovering the methyl mercaptan.
