二烷基二硫代磷酸锌的平衡解离及其与低氮分散剂的相互作用
摘要:
本文用31P-NMP研究了二烷基二硫代磷酸锌(ZDP)在内燃机基础油体系中的作用,发现在低浓度下从ZDP解离出一个含磷核的组份,化学位移为86ppm。表明ZDP在油中的溶解存在着依赖于浓度的化学平衡,通过这种平衡解离在ZDP与分散剂体系中的变化,研究了添加剂间的相互作用机理。

DISSOCIATION OF ZINC DIALKYLDITHIOPHOSPHATE AND ITS INTERACTION WITH SUCCINIMIDE DISPERSANT
Abstract:
The system of zinc dialkyldithiophosphate(ZDP) in lubricating base oil has been studied by using 31P-NMR. At low concentration of ZDP a phosphorated compound resonating at chemical shift of 86ppm was found. This indicates that there exists a chemical equilibri-um which is related to ZDP dissociation in the base oil and depends on the concentration of ZDP. A mechanism was proposed about the interaction between ZDP and succinimide dispersant.
