Summary A method for producing butadiene with high selectivity from 2,3-butanediol without the use of radioactive materials is disclosed. A method for producing butadiene includes a step of dehydrating 2,3-butanediol in the presence of a catalyst in which an alkali metal salt of phosphoric acid such as alkali metal dihydrogen phosphate is supported on silica. Here, preferable alkali metals include K, Rb and Cs, and the catalyst is preferably prepared by firing silica to which an alkali metal of phosphoric acid is attached. |
