Embodiment 1

[0063] The preparation of the pentadecylphenol of embodiment 1

[0064] 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

[0065] The preparation of embodiment 2 6-tert-butyl cardanol

[0066] 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

[0067] Example 3 Preparation of 3-pentadecyl-6-tert-butylphenol

[0068] 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 high-temperature chain oil composition and a preparation method thereof. The high-temperature chain oil composition comprises the following components: A) a phenolic compoundaccounting for 0.1%-15% (preferably 0.5%-10%) of the total mass of the composition; B) thioester accounting for 0.1%-10% (preferably 0.5%-5%) of the total mass of the composition; C) graphene nano particles accounting for 0.01%-10% (preferably 0.1%-5%) of the total mass of the composition; and (E) a main amount of lubricating base oil, the structure of the phenolic compound is shown as a general formula (I), and the definition of each group in the general formula (I) is shown in the specification, and the high-temperature chain oil composition has excellent wear resistance and oxidation resistance.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a high-temperature chain oil composition with excellent oxidation resistance. Background technique [0002] With the rapid development of industries such as petrochemicals, textiles, printing and dyeing, building materials and transportation, the power and operating speed of these equipments continue to increase, the operating temperature of the transmission system is getting higher and higher, and the requirements for chain oil are becoming increasingly stringent. High-temperature chain transmission works in an environment exposed to high and low temperatures, and the working temperature can reach above 200°C. The lubricating oil is very prone to oxidation, so it needs to have high high-temperature oxidation stability and good lubricity. The smooth operation of the chain and the small wear of the chain links depend on the good lubrication effect of the chain lubrication system, e...
