液态苯三唑脂肪胺盐合成及性能研究

以苯三唑和脂肪酸胺为原料，在氢氧化钠水溶液中进行化学反应，合成了液态苯三唑脂肪酸胺盐。采用四球试验、铜片腐蚀试验、高压差示扫描量热法(PDSC)、旋转氧弹法分别考察其抗磨性、抗腐蚀性、抗氧化性能，探索其在润滑油中的溶解度和低温油溶性。结果表明：液态苯三唑脂肪酸胺盐具有与固态苯三唑脂肪酸胺盐T406等同的抗磨性、抗腐蚀性和抗氧化性，对铜片防护能力好，呈现更好的油溶性和低温油溶性，可有效解决T406低温油溶性差的问题。实际生产过程中液态苯三唑烷基胺盐比T406更有利于润滑油品调合。

STUDY ON THE SYNTHESIS AND PERFORMANCE OF LIQUID BENZOTRIAZOLE ALIPHATIC AMINE DERIVATIVE

A kind of liquid benzotriazole derivative was synthesized by the reaction of benzotriazole and an aliphatic amine in sodium hydroxide solution. Tests including four ball machine, copper strip corrosion, PDSC, rotating bomb oxidation and so on were carried out to study its performance of antiwear, anticorrosion and antioxidation, as well as solubility with lube base oil, especially under low temperature. The results indicate that the performance of this prepared liquid benzotriazole derivative is equal to that of the commercial solid benzotriazole derivative T406, and its low temperature solubility in lube base oil is improved significantly, thus, it can be blended with base oil better and used more conveniently compared with T406 additive.
