| 摘要 |
Amine or polyol or alkylene oxide derivatives of Oxazoline reaction products of hydrocarbon substituted dicarboxylic acid, ester or anhydride, for example octadecenylsuccinic anhydride and polyisobutenylsuccinic anhydride with 2,2-disubstituted-2-amino-1-alkanols, such as tris-hydroxymethylaminomethane (THAM) are useful additives in oleaginous compositions, such as sludge dispersants for lubricating oil, or anti-rust agents for gasoline. |
