THIO-BIS-(HYDROCARBON-BISOXAZOLINES) AND ANALOGS AS OLEAGINOUS ADDITIVES

摘要

Thio-bis-(hydrocarbon-bisoxazolines) and analogs which are the reaction products of thio-bis-(hydrocarbon-subsituted dicarboxylic acid material), for example, thio-bis-(polyisobutenyl succinic anhydride), with about 1 to 4 moles of 2,2disubstituted-2-amino-1-alkanols, such as tris-(hydroxymethyl) amino-methane (THAM), and their derivatives are useful additives in oleaginous compositions, such as sludge dispersants for lubricating oil or anti-corrosion agents for fuels.
