Dialkylphenyl poly (oxyalkylene) polyamine ester compound for fuel oil detergent, fuel oil detergent concentrate and fuel oil composition containing the same, and production method thereof

摘要

The present invention relates to a new dimeric form of a dialkylphenyl poly (oxyalkylene) polyamine ester based fuel oil detergent which is effective as a precipitant regulator produced in an engine for an automobile. The present invention relates to an acrylic oil containing an alpha, beta unsaturated carbonyl group And then reacted with polyamine and Michael. The fuel oil detergent concentrate and the hydrocarbon fuel composition containing the fuel oil detergent concentrate were prepared by using the fuel oil detergent as an inactive organic solvent in an amount of 30 to 70 wt%. It is not necessary to use a process of eliminating the amine salt from being produced without using the poison gas which is used in the process of manufacturing the conventional polyether amine type fuel oil precipitate control additive and it is not necessary to use an excessive amount of polyamine to minimize consumption of amine And the removal of polyamines and the recovery of the polyamines are eliminated, thereby developing a novel clean cleaning performance through an economical process.
