摘要
借助红外光谱、紫外光谱、粘度、浊度等分析测试方法 ,考察了用不同的原料和工艺合成的丁二酰亚胺无灰分散剂与 ZDDP的相互作用。研究结果表明 ,丁二酰亚胺与 ZDDP的相互作用主要取决于丁二酰亚胺中活泼的伯胺氮含量 ,而伯胺氮含量则决定于丁二酰亚胺在生产中的烃化、胺化工艺和聚异丁烯基的结构。采用热储存及新工艺合成的单丁二酰亚胺 ,由于其部分重排成聚酰胺 ,减少了活泼的伯胺氨含量 ,从而改善了与 ZDDP的配伍性。
Interactions between zinc dialkydithiosphate( ZDDP) and succcinimide dispersants synthesized by differentfeeds and processes were investigated through changes in solutions behaviors,as determined by viscometry,infrared spectrometer,mass spectrometry and chemicalanalysis.The studies found that compatibility between ZDDP and succinimide dispersants primarily depended upon activeα amino group contentin succinimides. The activeα amino group contentwasaffected by thealkylation and amination processes,and also affected by the structureofpolyisobutylene in succinimides.Thesingle suc cinimide synthesized by the new process and storing undertemperture had less activeα amino group con tent,thus improved the compatability with ZDDP.
