采用2步法合成了一系列的脂肪酰胺丙基氧化胺类化合物，优化了2步法合成工艺，并研究了脂肪酰胺丙基氧化胺类物质在酸性体系中的增稠作用。结果发现，第1步酰胺化反应的最佳工艺条件为：n（N，N-二甲基丙二胺）：n（脂肪酸）=1．25：1，反应温度为160℃，反应时间10h，收率99％以上；第2步氧化反应的最佳工艺条件为：n（双氧水）：n（酰胺）=1．05：1，反应温度80℃，反应时间3h，催化剂用量为总质量的0．5％，收率99．4％。结果发现，肉豆蔻酰胺丙基氧化胺和棕榈酰胺丙基氧化胺在酸性体系下有明显的增稠作用。

A series of fatty amidopropyl dimethyl amine oxides were prepared through a two-step method in this paper. The technological conditions were optimized and the thickening effects were studied, The optimum experiment conditions of the amidation, which were obtained from the orthogonal test, were N, N-dimethyl propanediamine/fatty acid molar ratio of 1.25 ： 1, with reaction time of 10 h and temperature of 160 ℃. The product yield was higher than 99 %. The optimum conditions of the oxidation in a four-factor and three-level test were the hydrogen peroxide/fatty acid amide molar ratio of 1.05 ： 1, with 0.5% catalyst, reaction time of 3 h and temperature of 80℃ ; the product yield to 99.4%. The testing result demonstrated that both the myristic amidopropyl dimethyl amine oxide and the palmitic amidopropyl dimethyl amine oxide showed significant thickening effect under acidic conditions.
