Example Embodiment

[0029] Example 1:

[0030] 1. Put 20g of dried rapeseed oil in a three-necked flask, then slowly drop 5.2g of potassium hydroxide methanol solution with a mass concentration of 6% into the three-necked flask to react at 60°C, and control the dripping for about 20min. After the dropwise addition was completed, the reaction was incubated for 1 h. The product is washed to neutrality, dehydrated and dried to obtain FME;

[0031] 2. At 60°C, add 28ml of hydrogen peroxide dropwise to the mixed system of 10g FME, 15ml acetic acid and 0.5g catalyst strong acid cationic resin, H 2 o 2The molar ratio with acetic acid is 1.2:1, and the dropwise addition is controlled for about 2 hours, and the temperature is kept for 4 hours after the dropwise addition is completed. The product is washed to neutrality, and dried to obtain EFME;

[0032] 3. At 50°C, add 4ml of acetic acid dropwise to 15g of epoxy rapeseed oil, control the dropwise addition for about 1h, and keep warm for 2h after the ...

Abstract

The invention discloses a method for preparing organic silicon modified plant oil. The method comprises the following steps of: by taking colza oil as a raw material, preparing a colza oil alcohol orderly through methanol ester exchange, peracetic acid epoxidation and acetic acid ring opening; and then reacting organic silicon with the hydroxyl in the colza oil alcohol, thereby obtaining the organic silicon modified plant oil. The organic silicon modified plant oil produced by the method has good lubrication effect; and in addition, the oxidation stability of the organic silicon modified plant oil is also greatly improved.

Description

1. Technical field [0001] The invention relates to a method for preparing modified lubricating oil, in particular to a method for preparing organosilicon-modified vegetable oil. 2. Background technology [0002] The increase in world oil consumption and the decrease in reserves have prompted people to look for energy alternatives. In recent years, since various lubricant products will enter the natural environment through steam, leakage or spillage, the pollution of lubricants and environmental health issues have gradually attracted attention, and the development of environmentally friendly lubricants has become a global consensus. As the base oil of industrial lubricants, vegetable oil exhibits good lubricating performance, good corrosion resistance, good viscosity-temperature performance and low evaporation loss. In addition, compared to mineral oil, vegetable oil has better biodegradability and is a green and environmentally friendly lubricant. However, vegetable oil it...
