Difference Between Ethylene Glycol and Polyethylene Glycol

Difference Between Ethylene Glycol and Polyethylene Glycol

Difference Between Ethylene Glycol and Polyethylene Glycol:

Ethylene glycol and polyethylene glycol are two different compounds. Ethylene glycol is an organic compound with the chemical formula C2H6O2. It is a colorless, odorless, sweet-tasting liquid that is used as an antifreeze and coolant in automobiles and other machinery. It is also used in the manufacture of polyester fibers and resins.

Polyethylene glycol is a synthetic polymer made up of repeating units of ethylene glycol. It is a viscous, colorless, odorless liquid that is used as a lubricant, surfactant, and emulsifier in a variety of products. It is also used in the manufacture of cosmetics, pharmaceuticals, and food additives.

Polytetramethylene-Ether-Glycol

Ethylene glycol is a colorless, odorless, sweet-tasting, viscous liquid that is a simple diol (two hydroxyl groups on adjacent carbon atoms). It is used as an antifreeze and coolant in automobiles and other applications. It is also used as a solvent and in the manufacture of polyester fibers and resins.

Polyethylene glycol (PEG) is a polyether compound with many applications from industrial manufacturing to medical and pharmaceutical uses. It is a polymer of ethylene glycol with repeating ethylene oxide units. It is a viscous, colorless liquid that is soluble in water and many organic solvents. PEG is used as a surfactant, lubricant, and thickening agent in many products. It is also used as a drug delivery system and in the manufacture of cosmetics and personal care products.

1.4-Butanediol

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

Tetrahydrofuran (THF) is a colorless, volatile liquid with the odor of ether or acetone and is miscible with water and most organic solvents. THF is highly flammable and may thermally decompose into carbon monoxide and carbon dioxide.

BDO

图片
1.4-Butanediol ( BDO ) is used industrially as a solvent and in the manufacture of certain types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1.4-butanediol is used in the synthesis of gamma-butyrolactone (GBL). In the presence of phosphoric acid and high temperatures, 1.4-Butanediol dehydrates into the important solvent tetrahydrofuran. At about 200°C, in the presence of a soluble ruthenium catalyst, the diol undergoes a dehydrogenation reaction to form butyrolactone. BDO is used to synthesize 1,4-butanediol diglycidyl ether, which is then used as an epoxy resin diluent.
