Monoethylene glycol (CAS:107-21-1)thylene glycol, also known as ethylene glycol, is clear, colorless, syrupy, liquid with sweet taste. It is used as an antifreeze in cooling and heating systems. In organic synthesis, it is used as a protecting group for carbonyl groups. Ethylene glycol is miscible with water, ethanol, acetone, acetic acid, glycerol, pyridine, but difficultly soluble in chloroform, ether, benzene, carbon disulfide, and insoluble in hydrocarbons, chlorinated hydrocarbons, oils, rubber, natural resin. It also can dissolve table salt, zinc chloride, potassium carbonate, potassium chloride, potassium iodide, potassium hydroxide and other inorganic compounds.
