A cogeneration capacitor stage 2-butyl decanedioic acid and 2,9-dibutyl sebacic acid method

The invention relates to a co-production method for capacitance-grade 2-butylsebacic acid and 2, 9-butylsebacic acid. The co-production method comprises the steps of carrying out nucleophilic substitution reaction on diethyl malonate and 1, 6-dibromohexane serving as raw materials in a strong alkali solution to obtain 2, 9-bis(ethoxycarbonyl)-diethyl sebacate, then, enabling 2, 9-bis(ethoxycarbonyl)-diethyl sebacate to react with n-butyl bromide in the strong alkali solution, and distilling to obtain 2-butyl-2, 9-diethoxycarbonyldiethyl sebacate and 2, 9-dibutyl-2, 9-diethoxycarbonyldiethyl sebacate; and respectively saponifying, acidifying and carrying out decarboxylic reaction to obtain 2-butylsebacic acid and 2, 9-butylsebacic acid. Due to the improvement on a technological process, a byproduct, namely 2-butyl-8-thyoxyloctanoic acid is prevented from being generated, and high-purity 2-butylsebacic acid has more excellent electrochemical properties than 2-butyloctanedioic acid sold on the market, so that the oxidation efficiency of electrolyte is increased, and the co-production method has favorable market prospects.
