摘　　要：在酯化反应中应用反向滴加法,稳定了反应温度,提高了工业生产的安全性;在缩合阶段,通过双滴加法克服了以前工艺中产率低、副产物多等问题。对产品的应用性能进行了测试。The reaction temperature was stabilized and the safety of industrial production was improved by a reverse-dropping method in esterification. In condensation, the problems such as low-yield and multiple by-products of old processes were overcome by a two-dropping method. The performances of the products were determined.
