Abstract
The present invention is to provide a method of producing an alkene that can further enhance the yield of an alkene, a reaction product, the method including bringing a gaseous halogenated alkane into contact with an alkaline aqueous solution in the presence of a phase-transfer catalyst. The objective above is achieved by a method of producing an alkene comprising bringing in the presence of a phase-transfer catalyst a liquid phase containing an alkaline aqueous solution and a water-insoluble solvent into contact with a gas phase containing a halogenated alkane that is soluble in the water-insoluble solvent.
