Diethylene glycol dimethyl ether is also known as Diglyme or bis(2-methoxyethyl)ether.
It has good solubility and is miscible with many inorganic salts and organic compounds. It has good stability and is not susceptible to decomposition or oxidation reactions.
One of the main uses of diethylene glycol dimethyl ether is as a solvent. It has a strong solvency ability and can dissolve many organic and inorganic substances, and is widely used in chemical synthesis, extraction, electrolyte solvents and catalytic reactions. It can also be used as a component of coatings, adhesives and cleaning agents.
Diethylene glycol dimethyl ether can be produced by acid-catalyzed reaction of ethylene glycol and methanol. The specific steps are to mix ethylene glycol and methanol in a certain proportion and add an acid catalyst, and then carry out the reaction at an appropriate temperature. After the reaction is completed, the diethylene glycol dimethyl ether can be obtained by distillation and purification.
