Embodiment 1

[0043] Step (1) Add 1mol of benzoic acid derivative (A) to 10mol of dehydrated ethanol (B) and stir, add 0.5wt% sulfuric acid, heat and reflux at 120°C for 5h, pour it into ice water after the reaction is over, take the oil layer liquid, Carry out extraction and purification with ether, vacuum dry, obtain intermediate product I (IR: 3500cm -1 : -OH disappears; 3401cm -1 : Secondary-NH exists; 1689cm -1 :-C=O exists).

[0044] Step (2) 1mol I is dissolved in 10mol absolute ethanol, is added in the constant pressure dropping funnel, is added dropwise in the absolute ethanol that is dissolved with 1mol hydrazine (C), heats and refluxes for 18h, after the reaction finishes, the reaction mixes The solution was poured into crushed ice, filtered to obtain a precipitate, washed with water, and recrystallized from ethanol to obtain the intermediate product II (IR: 3402cm -1 : Secondary-NH exists and strengthens; 3483cm -1 : Presence of Bo-NH; 1689cm -1 :-C=O exists).

Abstract

The invention belongs to the technical field of lubricating oil, and relates to plant-based lubricating oil and a preparation method thereof. According to the method, aminobenzoic acid derivatives (A), absolute ethyl alcohol (B), hydrazine (C), carbon disulfide (D), 1,3-dichloro-2-hydroxypropane (E) and plant oil (F) are used as raw materials and subjected to esterification reaction, substitutionreaction, addition etherification reaction and other reactions, so that the plant-based lubricating oil is obtained. The plant-based lubricating oil has excellent wear resistance while the defects ofpoor oxidation resistance and high temperature resistance of existing plant-based lubricating oil are effectively overcome, and the synthetic raw materials are wide and environment-friendly. It can beforeseen that the product has a wide market space.

Description

technical field [0001] The 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 known since the invention of the wheel. Lubrication then becomes a problem that must be solved for mechanical equipment. Each working surface has a certain degree of roughness, and rough working surfaces cause friction. Friction can cause loss of surface material on the working face, resulting in surface wear. By using lubricants, wear can be minimized. The main purpose of lubrication is: (1) to reduce wear and prevent heat loss; (2) to prevent corrosion and reduce oxidation. [0003] Oil is the first thing that comes to mind when people think of lubricants these days. Petroleum base oils are the main components of lubricating oils. Although petroleum-based lubricants have many excellent physical properties, petroleum is non-re...
