发明名称 LUBRICATING OIL DISPERSANTS DERIVED FROM HEAVY POLYAMINE
摘要 <p>A functionalized hydrocarbon having functional groups of formula -CO-YR3 wherein Y is O or S, and R3 is H, hydrocarbyl or substituted hydrocarbyl, is derivatized with a heavy polyamine or with a heavy polyamine and a second amine to obtain an amide-containing product. The hydrocarbon is selected from hydrocarbon compounds and hydrocarbon polymers. The functionalized hydrocarbon can be prepared by reacting the hydrocarbon with carbon monoxide and a nucleophilic trapping agent. A heavy polyamine is a mixture of polyamines containing small amounts of lower polyamine oligomers such as tetraethylene pentamines and pentaethylene hexamine and containing primarily oligomers with more than 6 nitrogens and more extensive branching. The amide-containing products are useful as additives in fuels and lubricating oils.</p>
