Process for preparing methyl mercaptan

A process for preparing methyl mercaptan, comprising coupling the synthesis of hydrogen sulfide in a first reactor and the synthesis of methyl mercaptan in a second reactor to one another by

• obtaining a hydrogen sulfide mixture comprising uncompressed hydrogen sulfide from the first reactor which has a first pressure and adding methanol to the hydrogen sulfide mixture to give a reaction mixture, and
• introducing the reaction mixture into the second reactor which has a second pressure and preparing methyl mercaptan from said reaction mixture, wherein the first pressure and the second pressure gives a pressure difference which allows the reaction mixture to flow in the direction of the second reactor;
• and wherein the first pressure being higher than the second pressure.
