摘要
用饱和脂肪酸、乙二胺和丙烯酸合成制得N -酰胺基乙二胺 - β -氨基丙酸型两性加脂剂 ,最佳合成条件为两步反应温度分别控制在 80 - 90℃及 10 0 - 110℃和两步反应时间分别为 1h和 2h时 ,n(高级饱和脂肪酸 )∶n(乙二胺 )∶n(丙烯酸 )为 1∶1∶1,进行了加脂剂的应用试验及讨论了加脂剂对皮革中六价铬含量的影响 ,用FT
The amphoteric fatliquor of N-amido-ethylenediamine-β-aminoropionic acid types was synthesized by saturated fatty acid reaction with ethylenediamine and acrylic acid. The optimum synthesis condition of the two step chemical reaction were reaction temperature 80-90℃ and 100-110℃,reaction time 1h and 2h and n(fatty acid)∶n(ethylenediamine)∶n(acrylic acid)=1∶1∶1. The application experiment was carried out and the effect of the amphoteric fatliquor on the amount of hexavalent-chromium was also investigated. The structure of product was characterized by FT-IR.
