Monoethylene glycols are colorless, essentially odorless stable liquids with low viscosities and high boiling points. It is somewhat viscous liquid, miscible in water, soluble in ethanol, acetone, acetic acid, pyridine with a sweet taste. Ethylene glycol is prepared commercially by oxidation of ethylene at high temperature in the presence of silver-oxide catalyst, followed by hydration of ethylene oxide to yield mono, with di, tri and tetra-ethylene glycols as co products. 更多
