AUS SCHWEREN POLYAMINEN HERGESTELLTE MANNICHBASE DISPERGIERMITTEL FÜR SCHMIERÖLE |
摘要 |
An oil-soluble lubricating oil additive useful as a dispersant, comprising Mannich Base condensates of an alkyl (hydrocarbon or polymer) substituted hydroxy aromatic compound with an aldehyde and a heavy polyamine. A heavy polyamine is a mixture of polyalkylenepolyamines comprising small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentahexamine but primarily oligomers with 7 or more nitrogens, 2 or more primary amines per molecule, and more extensive branching than conventional polyamine mixtures. |
