辛酸钼的合成及其润滑性能研究

SYNTHESIS OF MOLYBDENUM CAPRYLATE AND STUDYON THEIR LUBRICATING PROPERTY

用辛酸为配体，在催化剂存在下与三氧化钼反应制备了两种辛酸钼，即正辛酸钼（ＭｏＣＹ１）和２－乙基己酸钼（ＭｏＣＹ２），用ＩＲ光谱确定了其结构．四球试验机的磨损评定结果表明，在用量大于或等于０．８％（质量分数）时，表现出较好的抗磨抗氧性能，且２－乙基己酸钼优越于正辛酸钼．用ＩＲ光谱探讨了ＭｏＣＹ１，ＭｏＣＹ２的润滑机理．

おolybdenum caprylate(MoCY1) and molybdenum 2ethylcaproate(MoCY2) were prepared with molybdenum trioxide and noctylic acid or 2ethylhexoic acid in the presence of catalyst, and verified by FTIR. The lubricating properties of the two molybdenum caprylates were tested. The results showed that their resistance to oxidation and abrasion were satisfactory, and that of MoCY2 was better than that of MoCY1. The mechanism of lubrication was discussed
