摘要：
Thirty-one hydrazides were selected as isosteres and other analogs when five phosphates were used as templates by an isosteric exchange from phosphate group (PO4) to hydrazide group (CONHN). Their tribological properties of the lubricant modified with 1% hydrazide or phosphate additives were tested under 98 N load in three base oils, respectively. About 40% of the isosteres showed an acceptable deviation of ±5% relative to the template. The phosphate template molecules and hydrazide isosteres have better tribological properties in triisodecyl ...
