Ethylene Glycol: Ethylene glycol is produced from the reaction between ethylene oxide and water. A high yield (90%) can be obtained when the reaction occurs at acidic or neutral pH, in the presence of excess amount of water. Asia holds a prominent share in the global market production of MEG Below a molecular weight of 700, it is an opaque liquid. Answer: The freezing points of these glycol solutions can be found in the tables below: Ethylene Glycol Solution (% by mass) 0: 10: 20: 30: 40: 50: 60: Figure 1: Chemical Structure of Ethylene Glycol. Although they have nearly similar names, polyethylene glycol and ethylene glycol are very different compounds depending on their chemical structures and general properties. For ethylene glycol, the mixing ratios are typically 30/70 and 35/65, whereas the propylene glycol mixing ratios are typically 35/65 and 40/60.

Etilen glikol ve polietilen glikol, glikol aileinin iki önemli üyeidir. However, anionic polymerization gives a low polydispersity. It is used in a number of toothpaste as a dispersant and as an anti-foaming agent in food industrial applications.

The type of polymerization depends on the type of catalyst. What is Ethylene Glycol – Definition, Properties, Uses 2. All rights reserved. Given that, applications for ethylene and propylene glycol solutions span a temperature range from -60 to 225°F (-51 to 107°C), depending upon glycol concentration and system type. Difference Between Ethylene Glycol and Polyethylene Glycol, What is the Difference Between Ethylene Glycol and Polyethylene Glycol, What is the Difference Between Tannin and Tannic Acid. Glycol is better known as ethylene glycol 2. Over a molecular weight of 900, it can be a white waxy solid, flakes or a powder. PEG is a clear liquid or a water-soluble white solid with a mild odor. Ethylene glycol has a melting point of 197.3 °C. Polyethylene glycol appears in a … Etilen glikol ve polietilen glikol araındaki temel fark, etilen glikol için abit bir moleküler ağırlık değerinin bulunmamaıdır, oya polietilen glikol için abit bir molekül ağırlık değerinin olmamaıdır..Hem etilen glikol hem de polietilen glikol hemen hemen benzer adlara ahip ola da, genel özellikleri ve kimyaal yapıları nedeniyle birbirlerinden farklı bileşiklerdir. The main difference between ethylene glycol and polyethylene glycol is that ethylene glycol has a fixed value for molecular weight whereas polyethylene glycol has no fixed value for molecular weight. The reaction between ethylene glycol and its oligomers is preferable than with water. Ethylene glycol is composed of two –OH groups in its structure. What is the Difference Between Ethylene Glycol and Polyethylene Glycol – Comparison of Key Differences, Key Terms: Ethylene Glycol, Hydrogen Bonds, Polydispersity, Polyethylene Glycol, Polymerization. It freezes at 32°F and boils at 212°F. When water is used for the reaction with ethylene oxide, the final product has a high polydispersity (the product has a high molecular weight distribution). The length of the polymer chain depends on the ratio of reactants. It is important that the … It has a faint sweet taste. It produces ethylene glycol when processed. Ethylene glycol has a fixed value of molecular weight which is about 62.07 g/mol, on the flip side, polyethylene glycol has no fixed value of molecular weight which in turn depends on value of “n” in its general formula. Polyethylene glycol (PEG) is a polymeric compound, and it is used in a wide range of areas such as chemical, biological, medical, industrial and commercial applications. Propylene Glocol Vs Ethylene Glycol. 20. Some of you who work on cars may have heard of the compound before. 1 Product Result Polyethylene glycol (PEG; / ˌ p ɒ l i ˈ ɛ θ əl ˌ iː n ˈ ɡ l aɪ ˌ k ɒ l,-ˌ k ɔː l /) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine.PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight.The structure of PEG is commonly expressed as H−(O−CH 2 −CH 2) n −OH. “ETHYLENE GLYCOL.” National Center for Biotechnology Information.
B. Propylene glycol is metabolized to more toxic compounds. Polyethylene glycol is a polyether compound, meaning that it consists of multiple ether groups. Polythene Glycol: Polythene glycol possesses a low toxicity and therefore it is used as a lubricating coating for both aqueous and non-aqueous environments. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Ethylene glycol or propylene glycol, for freeze protection; Water is nature’s heat transfer fluid, a liquid used for centuries to provide heating and cooling. The production of polyethylene glycol can be done form the reaction between ethylene oxide and water, ethylene glycol or ethylene glycol oligomers. The molecular weight of the compound varies depending on the value of “n” in this general formula. The main difference between ethylene glycol and propylene glycol is that ethylene glycol is toxic whereas propylene glycol is moderately toxic. - ( CH 2 O ) n ] it gives the final product with low.
