The formulations have excellent cold flow properties compared to similar formulations not containing the inventive adduct.
摘要:
There are disclosed macrocyclic and polycyclic polyamine lubricating oil additives formed by cyclodehydration of reaction products of hydrocarbon substituted succinic anhydrides or carboxylic acids with poly 3-amino propyl compounds or by acylation of macrocyclic polyamines and polycyclic polyamines with hydrocarbon substituted succinic anhydride or carboxylic acids. These compounds are useful as dispersants and dispersants-V.I. improvers in both gasoline and diesel engine lubricating oil compositions and are also useful fuel additives.
摘要:
This invention is a process for preparing Group I-B and II-B metal, preferably copper, salts of polyolefinic substituted dicarboxylic acids. The method involves the step of introducing substantially less than a stoichiometric amount of a short chain carboxylic acid (such as acetic or propionic acid), in a stagewise fashion, to a mixture of a source of the corresponding Group I-B or II-B metal (such as an oxide or hydroxide) with the polyolefinic substituted dicarboxylic acid. The product salt is then recovered.
