一种新型含磷极压剂的组成与结构研究

Study on Composition and Structure of a New Phosphoruscontaining Extreme-pressure Additive

采用溶剂萃取和柱层析的分离方法，使用红外光谱、核磁共振、质谱（包括ＥＩ－ＭＳ、ＦＤ－ＭＳ、ＦＡＢ－ＭＳ）等现代 仪器分析技术，对高档齿轮油复合添加剂的主剂——含磷极压剂的组成和结构进行了较为详尽的分析和研究，其 化学结构为硫代磷酸二己脂十二胺盐。

The composition and structure of a phosphorus-containing extreme-pressure additive in highgrade gear oil have been studied by FTIR, NMR, and various MS techniques, including EI/MS, FD/MS and FAB/MS. Solvent extraction and column chromatography were employed for the separation of the ingredi- ents. The dedecylammonium salt of dihexyl phosphorothionate was identified.
