Embodiment 1

[0043] Step (1) Add 1 mol of aminobenzoic acid derivative (A) to 10 mol of absolute ethanol (B) and stir, add 0.5 wt % sulfuric acid, heat under reflux at 120° C. for 5 h, pour into ice water after the reaction, and take the oil layer liquid , extracted and purified with ether, and dried in vacuo to obtain intermediate product I (IR: 3500cm -1 : -OH disappears; 3401cm -1 : Presence of secondary-NH; 1689cm -1 :-C=O exists).

[0044] Step (2) 1mol I was dissolved in 10mol absolute ethanol, added to the constant pressure dropping funnel, added dropwise to the absolute ethanol dissolved with 1mol hydrazine (C), heated to reflux for 18h, after the reaction was completed, the reaction was mixed. The liquid was poured into crushed ice and filtered to obtain a precipitate, which was washed with water and recrystallized from ethanol to obtain intermediate product II (IR: 3402 cm -1 : Presence and enhancement of secondary-NH; 3483cm -1 : Presence of primary-NH; 1689cm -1 :-C=O exis...

Abstract

The invention belongs to the technical field of lubricating oil. The invention relates to a vegetable-based lubricating oil and a preparation method thereof. The method comprises aminobenzoic acid derivatives (A), absolute ethanol (B), hydrazine (C), carbon disulfide (D), 1,3-dichloro- 2-Hydroxypropane (E) and vegetable oil (F) are used as raw materials, and a vegetable-based lubricating oil is obtained through multiple reactions such as esterification reaction, substitution reaction, addition etherification reaction, etc., which effectively solves the problem of existing vegetable-based lubricating oil. In addition to the defects of poor oxidation resistance and high temperature resistance, it also has excellent wear resistance, and the synthetic raw materials are widely used and environmentally friendly. It is foreseeable that the product has a broad market space.

Description

technical field [0001] The present invention relates to a vegetable-based lubricating oil and a preparation method thereof. The invention belongs to the technical field of lubricating oil. Background technique [0002] Lubricating moving parts has been widely known since the wheel was invented. Lubrication has then become a problem that mechanical equipment must solve. Each working surface has a certain roughness, and the rough working surface causes friction. Friction can cause the loss of surface material on the working surface, resulting in surface wear. Wear can be minimized by using lubricants. The main purposes of lubrication are: (1) to reduce wear and prevent heat loss; (2) to prevent corrosion and reduce oxidation. [0003] Today, when people think of lubricants, the first thing that comes to mind is oil. Petroleum-based base oils are the main component of lubricating oils. Although petroleum-based lubricants have many excellent physical properties, petroleum...
