1 results about "Methyl vinyl ketone" patented technology

The invention discloses a preparation method of methyl vinyl ketone. The preparation method comprises the following steps: contacting a raw material containing 1,3-butanediol with a copper-based catalyst to carry out reactions under a dehydrogenation condition, and contacting the reaction effluent with a solid acid catalyst to carry out reactions under a dehydration condition to obtain methyl vinyl ketone. The copper-based catalyst comprises the following components in percentage by weight: 40-50% of copper oxide, 35-45% of at least one of ytterbium oxide, nickel oxide, and zinc oxide, 0.1-1%of potassium oxide and the balance being aluminum oxide. A new preparation method of methyl vinyl ketone is provided, is easy to implement industrially, and is suitable for large scale production.
