Abstract

The invention discloses a modification method of phosphate compatible with positive ions. According to the method, phosphate and corn starch with various variabilities react; in addition, in the reaction, the reaction is more thorough in a mode of adding catalysts in the reaction and exerting disturbance magnetic field; next, phosphate starch obtained after the reaction is subjected to etherification and cationization treatment through 3-chloro-2-hydroxypropyltrimethyl ammonium chloride; finally, the stable and reliable phosphate modified organic matter compatible with positive ions is obtained. The stability of the phosphate compatible with positive ions is high; the compatibility with the positive ions is high; the high-temperature resistance performance and the anti-aging performance are realized.

Description

technical field [0001] The invention relates to the technical field of organic compounds, in particular to a cation-compatible phosphoric ester modification method. Background technique [0002] Phosphate, also known as orthophosphate (to distinguish it from phosphite), is an ester derivative of phosphoric acid and belongs to the category of phosphoric acid derivatives. Phosphoric acid is a tribasic acid, so according to the number of substituted hydrocarbon groups, phosphoric acid esters can be divided into primary phosphoric acid esters (monophosphoric acid esters, hydrocarbyl phosphoric acid esters), secondary phosphoric acid esters (phosphoric acid diesters) and tertiary phosphoric acid esters (phosphoric acid triesters) , are widely used in the field of metal processing industry to reduce friction and wear under high load induced boundary lubrication conditions. [0003] Therefore, phosphate esters are often used in complex structures in the machinery industry. Since p...
