Embodiment 1

[0069] The preparation of embodiment 1 pentadecylphenol

[0070] Put 100g of cardanol and 1.5g of palladium-carbon catalyst into a 200ml autoclave, seal the autoclave, feed hydrogen to 3.5MPa, start stirring, heating, and react at 200°C for 4.5 hours. After the reaction was completed, the temperature was lowered to 60°C, and the viscous reaction mixture was taken out, and distilled under reduced pressure at 100 Pa and 160°C for 1 h, and a milky white solid was obtained after cooling. Dissolve it with petroleum ether, and then crystallize and purify to obtain m-pentadecylphenol with a purity greater than 98%, and the reaction conversion rate is 83.6%.

Embodiment 2

[0071] The preparation of embodiment 2 6-tert-butyl cardanol

[0072] Dissolve 30g of cardanol into 100ml of acetone, put it into a 250ml three-necked flask, add 0.9g of zinc chloride catalyst, start stirring and heating. Maintaining the reaction temperature at 60°C, 9.5 g of tert-butyl chloride was slowly added dropwise into the reaction flask, and the reaction was continued for 3 hours after the dropwise addition was completed. After the reaction, the temperature was lowered to obtain a brown-red transparent liquid. After filtering the reaction product, wash it with 5% KOH solution, then wash it with distilled water to neutrality, distill under reduced pressure at 1000Pa and 120°C for 1h, remove the solvent, water and unreacted raw materials, and obtain a brown-red transparent viscous The thick liquid is 6-tert-butylcardanol, and the conversion rate of the product is 85.1%.

Embodiment 3

[0073] Example 3 Preparation of 3-pentadecyl-6-tert-butylphenol

[0074] Dissolve 30g of m-pentadecylphenol into 100ml of acetone, put it into a 250ml three-necked flask, add 1.5g of zinc chloride catalyst, start stirring and heating. Maintaining the reaction temperature at 50°C, 9.5 g of tert-butyl chloride was slowly added dropwise into the reaction flask, and the reaction was continued for 5 hours after the dropwise addition was completed. After the reaction, the temperature was lowered to obtain a brown-red transparent liquid. After filtering the reaction product, wash it with 5% KOH solution, then wash it with distilled water until it is neutral, distill it under reduced pressure at 1000Pa and 120°C for 1h, remove the solvent, water and unreacted raw materials, and obtain an orange-yellow color after cooling down. The solid is 3-pentadecyl-6-tert-butylphenol, and the conversion rate of the product is 80.1%.

Abstract

The invention provides a gasoline engine oil composition and a preparation method thereof. The gasoline engine oil composition comprises the following components: A) a phenolic compound; B) alkylationof diphenylamine; C) a polyisobutylene succinimide ashless dispersant and / or a boronized polyisobutylene succinimide dispersant; D) calcium sulfonate and / or vulcanized calcium alkyl phenolate; E) zinc dialkyl dithiophosphate; F) a compound friction modifier; G) a phosphite ester type extreme pressure anti-wear agent; and H) a major amount of lubricating base oil. The gasoline engine oil composition disclosed by the invention has excellent high-temperature cleaning performance, oxidation resistance and wear resistance. The composition has a sulfur content of not more than 0.5% and a sulfate ash content of not more than 1%; the content of phosphorus does not exceed 0.08%, the requirements of SM / GF-4, SN / GF-5, SN plus, SP / GF-6 and gasoline engine oil with the grade of SM / GF-4, SN / GF-5, SN plus, SP / GF-6 and the like can be met, and the occurrence frequency of low-speed pre-ignition can be remarkably reduced.

Description

technical field [0001] The invention relates to a gasoline engine oil composition, in particular to a gasoline engine oil composition with excellent oxygen resistance. Background technique [0002] In recent years, the rise of global oil prices and the increasing scarcity of oil resources have put forward more and more stringent requirements on the fuel economy of automobiles. At the same time, the fuel economy evaluation standards of engine oils have gradually become stricter. Economy puts forward higher and higher requirements. The specifications, grades and performance of gasoline engine oil continue to develop with the design, operating conditions and energy saving of gasoline engines, and vehicle lubricants are frequently upgraded. Gasoline engine oil product specifications are gradually upgraded from SL / GF-3 to SM / GF-4, to SN / GF-5, SN plus and SP / GF-6, which also puts forward higher requirements for lubricating oil additives. Energy-saving and environmental protectio...
