Abstract

The invention discloses a production method of a boron nitrided methyl oleate green lubricating additive. The method comprises the following steps that methyl oleate and a formic acid solution are mixed and put into a constant temperature bath, hydrogen peroxide is slowly and dropwise added, heating is conduced for a reaction, after the reaction is completed, oily liquid on the upper layer is washed with distilled water, vacuum dewatering is conducted, and epoxidized methyl oleate is obtained; epoxidized methyl oleate is mixed with water, phosphotungstic acid is added as a catalyst, and after a reaction is completed, hydroxylated methyl oleate on the upper layer is separated; hydroxylated methyl oleate and solid boric acid are mixed and react for 1 h under the conditions of mechanical stirring action and constant temperature of 120 DEG C, after the reaction is completed, triethanolamine is added, a reaction is continuously conducted for 1 h, after the reaction is completed, oily liquid on the upper layer is separated and purified, and boron nitrided methyl oleate is obtained. According to the production method of the boron nitrided methyl oleate green lubricating additive, the synthetic process is simple, the raw materials are rich in source, the production cost is low, and the obtained green lubricating additive is good in biodegradability and can replace traditional lubricating additives containing sulfur, phosphorus and chlorine.

Description

technical field [0001] The invention relates to the field of oleochemistry, in particular to a production method of boronitrided methyl oleate green lubricating additive. Background technique [0002] At home and abroad, the preparation of green lubricating additives mainly follows the preparation method of traditional mineral oil additives, that is, on the basis of studying the laws of lubricant adsorption on the surface of friction pairs and tribochemical behavior, to screen some non-toxic or low-toxic and easy to use in friction. The interface is adsorbed and undergoes tribochemical reaction to generate functional elements or groups of adsorption film or tribochemical reaction film with low shear strength and good extreme pressure performance, and carry out "group assembly" to synthesize non-toxic and biodegradable green lubricant Additives, additives have high preparation costs and complex synthesis routes. [0003] Since the 1950s, oleochemistry has become an important...
