Ethylene glycol dimethyl ether (DME) is a water-white neutral liquid with an ether smell. It is stable and does not react easily. It can dissolve various resins and cellulose, and can mix with water and many alcohols. Ketones, esters and other organic solvents are miscible in any proportion, and their solubility can be adjusted by appropriate dilution with water or certain solvents. DME is an aprotic polar solvent with excellent performance. In addition to being used as a gas absorbent, extractant and paint stripper, it can also be used in the following chemical fields.
Main applications:
Used in electrochemistry: Due to the special structure of DME, it can replace water as a non-aqueous electrolyte solvent and is used in electrochemical equipment, rechargeable batteries and electrolysis reactions of organic compounds. wait. For example, if an aqueous solution system of benzene, tetrabutylammonium bromide, and DME undergoes an electrolysis reaction, 1,4-dihydroxybenzene with a purity of 96% can be produced.
Preparation of Boron Chemistry: DME as a solvent can be used to prepare various boron derivatives such as boron, borohydride, polyborohydride, polyborohydride and so on. For example, trialkyl boride and sodium aluminum hydride are reacted in DME to produce sodium borohydride with high purity and large particles. Preparation of organometallic compounds.
DME is an important reagent in organometallic reactions and can be used to prepare antimony. Selenium, tin, titanium, rhenium, iron, ruthenium and other organic metal compounds. Used in the polymerization reaction of polymer materials; used as a cleaning agent compound; used in the synthesis of organic compounds and pharmaceutical intermediates, etc.
