用^（31）P－NMR和IR谱研究MoDTP合成产物组分及反应机理

Study on the Composition of Molybdenum Dithiophosphate Synthetic Products by￣(31)P-NMR and IR Spectroscopy

用^（３１）Ｐ核磁共振（ＮＭＲ）谱和红外（ＩＲ）光谱研究了二硫代磷酸钼（ＭｏＤＴＰ）合成产物组分含量、分子结构及其合成反应机理。结果表明，ＭｏＤＴＰ合成产物是由３７．２％的有机五价钼络合物、３５．１％的有机Ｐ＝Ｓ化合物和２７．７％的有机Ｐ＝Ｏ化合物等１４种成分组成，所含副产物或由原料带入，或因ＭｏＤＴＰ合成反应过程原料本身副反应伴随产生。

The reaction mechanism,the composition and structure of molybdenum dithiophosphate synthetic products were studied by 31P-NMR and IR spectroscopy.Fourteen components have been identified.Among the reaction products, 37.2% are organomolybdenum(V)complexes, 62.8% are organic compounds containing 35.1%Organic P=S compounds,and 27.7% organic P=O compounds.The products came either from the raw material as impurities,or from side-reactions as by-products of molybdenum dithiophosphate synthesis.
