Application
Tetraethylene glycol dimethyl ether is mainly used in the following fields:
Chemical reaction solvent:
Tetraethylene glycol dimethyl ether, as a Lewis basic solvent, is commonly used in alkylation condensation, reduction reactions, and organometallic reactions, and is an excellent solvent for inorganic salts such as sodium borohydride.
Gas purification:
The Lewis basicity of Tetraethylene glycol dimethyl ether enables it to selectively absorb acidic gases(such as synthesis gas, natural gas, acetylene, etc.) for gas purification processes.
Other applications:
Organic synthesis: Tetraethylene glycol dimethyl ether is used as an inert solvent to reduce the viscosity of prepolymers and replace solvents with similar properties.
In the industrial field, Tetraethylene glycol dimethyl ether is used as a cleaning agent, catalyst and additive.
Storage
Store in a cool, dry, well ventilated environment, away from sources of fire and strong oxidants.
Avoid direct sunlight and humid environments to prevent accelerated oxidation reactions.
