摘　　要：对原有的生产工艺进行了改进,用另一种缚酸剂氧化钙替代原有的缚酸剂三乙胺,大大简化了缚酸剂的回收工艺,缩短了反应时间,收率从原来工艺的92%￣93%提高至97%以上,克服了老工艺三乙胺回收困难、损耗大、产量小的缺点。Inherent methodology was improved by using calcium oxide substituting triethylamine, that reducing recovering methodology of triethylamine and contracting reaction time. Yield was improved from 92-93% to above 97%. Thereby overcoming the disadvantages of difficulty of recovering triethylamine, mass loss and small product.
