Lubricating oil dispersants derived from heavy polyamine
摘要
A Koch functionalized product, which is the reaction product of at least one hydrocarbon with carbon monoxide and a nucleophilic trapping agent is derivatized with a heavy polyamine. A heavy polyamine is a mixture of polyamines comprising small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentahexamine but primarily oligomers with more than 6 nitrogens and more extensive branching.
