摘要
研究了以壬酸酐和对羟基苯磺酸钠为原料,丙酮为溶剂,无水碳酸钠为缚酸剂,合成过氧化氢漂白活化剂壬酰氧基苯磺酸钠的清洁工艺,考察了影响合成反应的主要因素。适宜的工艺条件为:n(对羟基苯磺酸钠):n(壬酰酐):n(无水碳酸钠)=1:1.3:1.5,反应温度0～5℃,反应时间3h,壬酰氧基苯磺酸钠的收率为90.7%,质量分数为95.5%。结果表明,该工艺具有操作简单、易控,产品质量好、收率高,环境友好等优点。
A clean process for synthesis of sodium nonanoyloxybenzene sulfonate by sodium 4-phenolsulfonate and nonanoyl anhydride in acetone and sodium carbonate as an acid-captor in a one-step process was studied.The influences of some factors on the synthesis process were investigated.The optimal reaction conditions were chosen as follows：molar ratio of nonanoyl anhydride to sodium 4-phenolsulfonate 1.3：1,molar ratio of nonanoyl anhydride to sodium carbonate1.3：1.5,reaction temperature 0～5℃,reaction time 3 h.The yield reached 90.7%,mass fraction of the target product 95.5%.The new process aproved to have many advantages,such as easy preparation,non-corrosive to equipment,good quality to products and pollution-free to environment.
