Mainly used as a solvent. It is used as a solvent for alkali metal hydroxides in metal-organic compound synthesis, alkylation reactions, polycondensation and reduction reactions.
This product is an aprotic polar solvent, can be used for polar organic reaction, anionic polymerization, coordination ion polymerization reaction solvent, can be used as reduction, alkylation and condensation reaction solvent, can also be used as a medium for Grigoll and similar synthesis, but also used as a pollution-free cleaning agent, extraction agent, diluent, pharmaceutical additives and resin solvent.
Diethylene glycol DME is also known as Diglyme or bis(2-methoxyethyl)ether.
It has good solubility and can be miscible with many inorganic salts and organic compounds. It has good stability and is not easy to decompose or oxidize.
One of the main uses of diethylene glycol dimethyl ether is as a solvent. Its dissolution ability is strong, can dissolve many organic and inorganic substances, widely used in chemical synthesis, extraction, electrolyte solvent and catalytic reaction and other fields. It can also be used as an ingredient in paints, adhesives and cleaning agents.
Diethylene glycol dimethyl ether can be prepared by an acid-catalyzed reaction of ethylene glycol and methanol. The specific step is to mix ethylene glycol and methanol in a certain proportion, and add an acidic catalyst, and then react at the appropriate temperature. After the reaction is completed, diethylene glycol dimethyl ether can be obtained by distillation and purification.
