丙二酸二甲酯合成的研究

A Research on the Preparation of Dimethyl Malonate

丙二酸二甲酯是医药、农药和染料的中间体，目前国内老方法生产收率只有６５％（以氯乙酸为基础）。本文通过对丙二酸二甲酯合成新方法的研究，收率达到８０％以上。产品质量和标准样品一致。

Dimethyl malonate useful as intermediates for medicines,agrochemicals and dyes,were pre-pared by old methods in out country.The yield of dimethyl malonate(based on Cl CH2COOH)was 65%. In this paper a new method on the Preparation dimethyl malonate has been proposed.The total yield was more than 80%.
