Properties and stability
Avoid contact with strong oxidants and acids. Ethylene glycol-isopropyl ether is non-corrosive to metals.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. They should be stored separately from oxidants, acids, and food chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
Refining method: dry with calcium chloride or anhydrous sodium sulfate and then fractionate.
Purpose
Used as a solvent for coatings such as nitrocellulose paint. Due to its low hygroscopicity, when used as a coating solvent, the coating film is not prone to emulsification.
