Resolve Resolution | First, 2,2-dimethyl-1,3-propanediol is used as a starting material, which is oxidized to a crude 2,2-dimethylmalonic acid and recrystallized to obtain 2,2-dimethylpropane Pure acid. Then, the Lewis acid was used as a catalyst, 2,2-dimethylmalonic acid was subjected to an esterification reaction with methanol, and an alkane was used as a water carrier. After the reaction, the solvent was distilled off and applied, and the product was washed with water, dried, and distilled under reduced pressure to obtain the product. |
Application | Dimethyl 2,2-dimethylmalonate is a versatile organic compound. Widely used in pharmaceutical piperidine acid intermediates and perfume intermediates, synthetic raw materials for pesticide intermediates. |
