Method for Producing Alpha, Beta-Unsaturated Alcohol

摘要

A method of producing an α,β-unsaturated alcohol at a high conversion ratio and a high selectivity is provided, which comprises continuously supplying a gas mixture containing an α,β-unsaturated aldehyde and at least an equimolar amount of a secondary alcohol using zirconium oxide as a catalyst to thereby produce the corresponding α,β-unsaturated alcohol through a hydrogen transfer reaction from the secondary alcohol. According to this method, crotyl alcohol can be produced at a high yield from crotonaldehyde using isopropanol as a hydrogen source, the crotonaldehyde being obtained by dehydrogenating bioethanol to produce acetaldehyde and then subjecting acetaldehyde to aldol condensation.
