The invention relates to a process for continuously preparing methyl mercaptan by reacting a mixture comprising carbon compounds with sulfur and hydrogen, wherein the carbon disulfide and hydrogen sulfide compounds which form are subsequently converted to methyl mercaptan.

Method of producing hydrogen sulfide in an alkaline environment. A mixture having a sodium salt, elemental sulfur (S) and water is added to a reactor for the purpose of generating hydrogen sulfide (H.sub.2S) gas as the main product and sodium sulfate (Na.sub.2SO.sub.4) as a byproduct.

The present disclosure provides autocatalytic cycles and chemical reactor systems in which the autocatalytic cycles may be conducted. Also provided are methods of identifying the autocatalytic cycles and methods of conducting the autocatalytic cycles, e.g., to produce a desired product. Regarding the methods of conducting the autocatalytic cycles, such a method comprises: carrying out a comproportionation reaction by reacting a first reactant M.sub.1 and a second reactant M.sub.2 to form a product M.sub.3, wherein M.sub.1, M.sub.2, and M.sub.3 each comprise at least one chemical element in common and the product M.sub.3 is produced in stoichiometric excess; and carrying out an auxiliary reaction by converting the product M.sub.3 to M.sub.1 or M.sub.2.
