Embodiment 1

[0032] Weigh 64.2g of dihydroxyethyl octadecylamine into a 1000ml three-necked flask, add 0.5g of catalyst, and then add 300ml of toluene as a solvent, and reflux under magnetic stirring. Weigh 34g of ammonium tungstate pentahydrate aqueous solution, and slowly add it dropwise into a three-necked flask using a constant pressure dropping funnel. The temperature of the reaction system is controlled between 90 and 100°C, and the reaction time is about two hours. Use a water separator to separate the upper water layer, filter to obtain a grass-green product, and then vacuum-dry to obtain a grass-green solid, namely N-octadecyliminediethanol tungstate diester. The reaction equation is as follows:

[0033] .

[0034] The N-octadecylimine diethanol tungstate diester additive prepared according to the steps of the above method was used for oil solubility determination. According to the mass fraction of 0.05, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 N-octadecyl imine diethanol tungstate diest...

Abstract

The invention belongs to the field of diesel engines, and particularly relates to an environment-friendly antifriction and antioxidant non-sulfur phosphorus organic tungsten additive and lubricating oil containing the same. The lubricating oil is prepared by dropwise adding an aqueous ammonium tungstate pentahydrate solution into a methylbenzene solution of dihydroxy octadecylamine, heating to 90-100 DEG C, reacting for two hours, performing reduced pressure distillation, drying to obtain N-octadecyliminodiethanol tungstic diester, adding the N-octadecyliminodiethanol tungstic diester into mineral base oil and alkyl naphthalene base oil, and mixing with polymethacrylate, a non-dispersive ethylene-propylene copolymer, synthetic low-chlorine long-chain linear alkylbenzene magnesium sulfonate, overbased sulfurized calcium alkylphenol, high-molecular weight polyisobutenyl succinimide and zinc bioctyl alkyl thiophosphate; the lubricating oil is free of sulfur and phosphorus, and has environment-friendly, energy-saving, antifriction, antioxidant and precipitate-free excellent performance.

Description

technical field [0001] The invention belongs to the field of diesel engines, and in particular relates to an environment-friendly anti-friction and anti-oxidation non-sulfur phosphorus organic tungsten additive and lubricating oil containing the additive. Background technique [0002] Diesel engine oil is an important lubricating oil formulated mainly from paraffinic base oil or synthetic lubricating oil, with various additives such as anti-oxidation, anti-corrosion, detergent and dispersant, and friction reducer. [0003] With the development of modern diesel engines, in order to meet the goals of emissions, fuel economy and long oil drain intervals, as well as user expectations for reliability and better driving experience, the design of powertrain systems has become more complex. These complex The engine system needs to be matched with advanced lubricating oil; in order to meet the emission and long oil change intervals of oil products, engine lubricating oil needs better...
