  • Method for preparing low-grade unsaturated fatty acid ester
    Patent number: 10919832
    Abstract: Provided is a method for preparing a lower unsaturated fatty acid ester, which comprises carrying out an aldol condensation reaction between dimethoxymethane (DMM) and a lower acid or ester with a molecular formula of R1—CH2—COO—R2 on an acidic molecular sieve catalyst in an inert atmosphere to obtain a lower unsaturated fatty acid or ester(CH2?C(R1)—COO—R2), wherein R1 and R2 are groups each independently selected from the group consisting of H— and C1-C4 saturated alkyl group.
    Type: Grant
    Filed: November 25, 2016
    Date of Patent: February 16, 2021
    Assignee: Dalian Institute of Chemical Physics, Chinese Academy of Sciences
