    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a 2-cycloalkenone by an elimination reaction from an alkoxycycloalkanone or a hydroxycycloalkanone ketal under an acidic heterogeneous catalytic action, capable of simply producing the 2-cycloalkenone in a high yield in one process. SOLUTION: This method for producing a 2-cycloalkenone of formula III comprises subjecting a 2-alkoxycycloalkanone of formula I [(n) is 0-20; (m) is 0-3; R is an alkyl, an alkylaryl, an aryl, an arylalkyl, an alkenyl or an alkynyl; R' is an alkyl, an alkenyl or the like] or 2-hydroxycycloakanone ketal or a mixture of the compound of formula I with the compound of formula II to an elimination reaction in the presence of an acidic heterogeneous catalyst in a gas phase. The acidic heterogeneous catalyst preferably contains at least one oxide or phosphoric salt, or a mixture of the oxide with the phosphoric salt, or the mixed oxides of the groups 3-6 and the groups 13-15 elements in the periodic table.

    Abstract: Disclosed is a method for producing organic disulphide by oxidation of the corresponding thiol with sulphur disolved in organic disulphide using an amine as a catalyst in a reaction column (K). The thiol used is a crude thiol flow from catalytic reaction of the corresponding primary alcohol with hydrogen sulphide and the bases of the reaction column (K) are temperable.
