摘    要：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.

Abstract: Molybdenum caprylate (MoCY₁) and molybdenum 2-ethylcaproate (MoCY₂) 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 MoCY₂ was better than that of MoCY₁. The mechanism of lubrication was discussed.
