use | this product is an intermediate of antiepileptic drugs and antiepileptic spirit. |
production method | obtained by hydrolysis of diethyl dipropyl malonate. Diethyl dipropylmalonate, ethanol and potassium hydroxide solution with relative density of 1.4 were mixed and stirred, and refluxed for 4 hours. Recover ethanol, cool, acidify with hydrochloric acid to pH 1, and let stand. Filtration, drying, to obtain dipropylmalonic acid. 80% yield. |
