The invention belongs to the field of chemical industry and discloses a method for synthesizing 4-methyl-2-pentanol by hydrogenation of methyl isobutyl ketone. The method comprises: preheated methyl isobutyl ketone is in a partially liquid form Enter into the supergravity rotating bed reactor, contact with the preheated hydrogen in the catalyst bed arranged on the rotor of the supergravity rotating bed reactor, and generate a product stream containing 4-methyl-2-pentanol, wherein , the liquid content of methyl isobutyl ketone in contact with the hydrogen is not less than 50%. The invention proposes a method for preparing 4-methyl-2-pentanol by hydrogenating methyl isobutyl ketone in a hypergravity field. The method can significantly reduce reaction temperature and reaction pressure, increase liquid hourly space velocity, and prolong catalyst It has a certain industrial application value. |
