新型防锈润滑添加剂的合成与红外光谱表征

The synthesis and spectral characterized of a new anti-rust lubricant additive

本文以壬基酚聚氧乙烯醚、顺丁烯二酸酐和二己醇胺为原料，合成了一种具有防锈、润滑双重性能的水基合成切削液添加剂——琥珀酸壬基酚聚氧乙烯醚酯二乙醇酰胺。酯化条件为：酸酐：OP（摩尔比）：1．0：1．2，反应温度为90-95℃，反应时间为3h；酰胺化条件为：琥珀酸壬基酚聚氧乙烯醚单酯：二乙醇胺（摩尔比）为1：1．3，反应温度为140-160℃，反应时间为2—4h。采用红外光谱法对中间体和产物进行表征，从而确定了合成的最佳工艺路线和工艺条件。

In the paper, the nonyl phenol polyethylencoxide ether amber diehylene glycol dinitrate diglycollic amide was synthesized by using nonyl phenol polyethyleneoxide as raw meterial.The product is a kind of additive in water soluble cutting fluid, and it has anti - rust and lubricant double functions. The esterification condition was that anhydride： OP（mole ratio）was 1 .0：1.2, reaction temperature was 90 - 95℃, reaction time was 3h.The amidate condition was that nonyl phenol polyethyleneoxide monoether： diethanolamine was 1. 0： 1.3, reaction temperature was 140 - 160℃, reaction time was 2 - 4h.The constructs of raw material, intermediate and product were characterized by IR. So, the optimum synthesis processc conditions were obtained .
