烃基的结构对有机钼化合物极压抗磨性能的影响

Influence of the Structure of Alkyl on the Properties of Organo-compounds Containing Mo

报道了烃基对含S、Mo有机化合物和含S、P、Mo有机化合物的油溶性 ,热稳定性以及极压抗磨性能的影响。研究表明 ,随着烃基中碳原子数的增加 ,两类有机化合物的热稳定性增加 ,极压抗磨性能下降。含S、P、Mo有机化合物的油溶性不随烃基的变化而变化 ,而含S、Mo有机化合物的油溶性随着烃基中碳原子数的减小而下降 ,两类化合物的临界负荷还与烃基中碳原子的连接方式有关。

The influence of the structure of alkyl on the properties of organo-compounds containing S,Mo or S,P,Mo was investigatedIt was shown that the thermostabilities of these compounds increase and their load-carrying ability decrease with the increase of the number of carbons in alkylsThe compound with branced alkyls shows higher load-carrying ability The alkyl do not affect the oil-solbuility of the compounds containing S,P,Mo(Ⅵ)
