摘　　要：对丙二酸酯类化合物脱羧反应应用于工业上的优劣进行了比较,工业化实践表明,热解脱羧法收率最高,经工业化验证,产品总收率达到95%,比文献收率提高了约30个百分点。s： Different decarboxylation methods of malonic acid ester compounds in industry was compared. It was showed that the pyrolysis of decarboxylation method gave the best result which was also testified by scaling up in industry. The yield increased from 63 % to 95 % totally, which was compared with the document.
