Liquid cooling medium synthesis method of liquid cooling server

Abstract

The invention provides a liquid cooling medium synthesis method of a liquid cooling server. The method comprises the steps of S1 preparing 350mL of metal hydroxide aqueous solution with the concentration of 0.2 to 4mo l / L, and introducing the metal hydroxide aqueous solution into a pressure-resistant and corrosion-resistant reaction kettle through a funnel in a vacuum state; S2 adding a chlorine-containing ether compound, a fluorination reagent and an aprotic solvent into a fluorination electrolytic cell for fluorination to generate a chlorine-free hydrofluoroether base solution; and S3 introducing a hexafluoropropylene oxide oligomer into the reaction kettle through a funnel, setting the rotating speed of the reaction kettle to be 100 to 450 rpm, after the hexafluoropropylene oxide oligomer and the metal hydroxide solution are fully mixed, slowly increasing the reaction temperature of the reaction kettle to be 20 to 250 DEG C. The process defects of high corrosivity, high energy consumption and high risk of electrolytic fluorination and the limitation problem of fluorocarbon cyclic ether can be well overcome.

Description

[technical field] [0001] The invention relates to the technical field of liquid cooling medium synthesis methods, in particular to a liquid cooling medium synthesis method for liquid cooling servers with outstanding application effects. [Background technique] [0002] Hydrofluoroether is a class of ether compounds containing fluorine, carbon, hydrogen, and oxygen elements. Its ozone depletion potential (ODP) is zero, its greenhouse effect potential (GWP) is low, and its atmospheric residence time is very short. It is an ozone-depleting substance. new generation substitutes. Pure hydrofluoroether has good miscibility and has important applications in cleaning, refrigeration, foaming, medicine and other fields.

AI Technical Summary

Problems solved by technology

[0003] Patent CN1651378A reports that when dimethyl sulfoxide DMSO is used as a solvent and fluorine-containing olefins and fluorine-containing alcohols are used as raw materials to prepare hydrofluoroether, not only is it difficult to separate the final product, but also the recovery cost of the solvent is relatively high due to the high boiling point of DMSO itself. high

Although the preparation of hydrofluoroethers in CN102115428A does not use solvents and fluorine-containing catalysts, the reaction conditions are relatively harsh, requiring relatively high temperature and pressure

Therefore, need a kind of method for preparing hydrofluoroether compound that can solve above-mentioned technical problem, at present, the method for preparing corresponding hydrofluoroether by hexafluoropropylene oxide oligomer in aqueous solution has not been reported yet
