Provided is a method capable of producing an olefin with high selectivity and high yield using a vicinal diol as a raw material. A method for producing an olefin includes a step of reacting a compound including two adjacent carbon atoms each containing a hydroxy group with hydrogen and forming an olefin, and in this step, the reaction of the compound including two adjacent carbon atoms each containing a hydroxy group with the hydrogen proceeds in the presence of a catalyst under a condition substantially free of a solvent. The catalyst includes a carrier, at least one oxide supported on the carrier and selected from the group consisting of oxides of group-6 elements and oxides of group-7 elements, and at least one metal supported on the carrier and selected from the group consisting of silver, iridium, and gold.
A method for producing butadiene, the method comprising an olefinating step of reacting erythritol with hydrogen and forming the butadiene, wherein in the olefinating step, a reaction of the erythritol with the hydrogen proceeds in the presence of a catalyst under a condition substantially free of a solvent, wherein the catalyst is ReOX—Au/CeO2 or ReOX—Ag/CeO2.
A catalyst for an olefination reaction, the catalyst, to be used in a reaction of erythritol with hydrogen forming butadiene, comprising a carrier, a film of at least one oxide supported on the carrier and selected from the group consisting of oxides of group-6 elements and oxides of group-7 elements, and a film of at least one metal supported on the carrier and selected from the group consisting of silver and gold,
