摘要： A production method in which a mercaptophenol compound is obtained using an industrially preferred sulfur atom introduction reaction, and intermediate compounds of the mercaptophenol compound are provided. A method for producing a mercaptophenol compound in which a phenyl carbamate compound is produced using a phenol compound as a raw material, and then a sulfur atom is regioselectively introduced by a reaction with sulfur monochloride, and a phenyl mercaptocarbamate compound is produced as an intermediate.

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.
