  • Continuous production of methyl pentenone using cation exchange resin in a fixed bed reactor
    Patent number: 11661391
    Abstract: Provided herein is a method for producing methyl pentenone (MPO) in high yield in a continuous mode in a fixed bed reactor having a plurality of sidewall injecting ports by reacting excess methyl ethyl ketone (MEK) with acetaldehyde in presence of a cation exchange resin catalyst, wherein the acetaldehyde is injected from the plurality of sidewall injecting ports of the reactor. The method is also effective in reducing the complete consumption of the catalyst during the course of the reaction.
    Type: Grant
