摘　　要：在现有的抗氧剂知识体系上,通过抗氧剂分子的构效关系研究,设计出含硫酚型抗氧剂,同时考察了合成抗氧剂和现有胺型抗氧剂的复配效应,确定了合适的复配比例;在高档汽油机油中通过了ⅢG台架试验,表明合成的高温抗氧剂满足了高档内燃机油的需求。Based on the structure-activity relationship of antioxidant molecules,a sulfur-containing phenol antioxidant was designed in the existing knowledge on the antioxidant system.The synergistic effect of both phenol and diphenylamine antioxidants was studied and the proportion of them was determined.The result of passing ASTM Sequence Ⅲ showed that the high temperature antioxidant can meet the demand of high grade internal combustion engine oil.
