Ethylene glycol butyl ether is one of the important derivatives of ethylene oxide (EO). It is a green and environmentally friendly solvent, a colorless liquid, with a molecular weight of 118.17, a distillation range of 163-174°C, not volatile, a relative density of 0.9019, a boiling point of 171.1°C, a flash point of 60.5°C, and is toxic. It is miscible with water and hydrocarbon solvents such as linseed oil, and has a strong solubility for synthetic rubber. It is suitable as a solvent for natural rubber and synthetic rubber, and is also used as a solvent for rosin, shellac, shellac, oxyindene resin, ethyl cellulose and nitrocellulose.

Diethylene glycol butyl ether is a colorless liquid, soluble in water and oils. It is prepared by heating ethylene oxide and ethylene glycol butyl ether under pressure.
