摘　　要：研究了n(吗啉)/n(促进剂M)、n(H2O2)/n(促进剂M)、双氧水浓度、反应温度和时间对双氧水氧化法合成促进剂NOBS的影响,通过L16(45)正交实验确定出的最佳合成配方及工艺条件:n(吗啉)/n(促进剂M)为7;n(H2O2)/n(促进剂M)为1.6;双氧水浓度为12%;反应温度为40℃;反应时间为3h。产品纯度(质量分数)不小于98.5%,平均熔点为84.5℃。The influence factors such as n(morpholine)/ n(accelerant M),n(H_2O_2)/n(accelerant M),the concentration of hydrogen peroxide,reaction temperature and time were studied to find how they affected the synthesizing of accelerant NOBS adopting hydrogen peroxide oxidation method.By L_ 16(4~5) orthogonal test the optimized synthesis formulation and process conditions were obtained as follows:n( morpholine )/n(accelerant M) was 1.6,n(H_2O_2)/ n(accelerant M) was 1.6,the concentration of hydrogen peroxide was 12%,the reaction temperature was 40 ℃,the dripping time of hydrogen peroxide was 3 h.The results showed that the product purity(mass fraction) was not less than 98.5% and the average meting point was 84.5 ℃。
