2-(4’-甲基苯磺酸基)丙酸乙酯的合成新方法
New Synthesis Techniques for 2-(4’-Methyl benzenesulfonic acyloxy)ethyl Propionate
【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。
【Abstract】 Inherent methodology was improved by using calcium oxide substituting triethylamine, that reducingrecovering methodology of triethylamine and contracting reaction time. Yield was improved from 92- 93% to above97%. Thereby overcoming the disadvantages of difficulty of recovering triethylamine, mass loss and small product.
