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. Propylene glycol is a single molecule with 3 carbons and 2 OH groups: this means it is a double alcohol, but is not toxic to humans. PEG is the base for many skin creams and personal lubricants. It is a viscous liquid. Compare the Difference Between Similar Terms. 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. The IUPAC name of ethylene glycol is ethane-1,2-diol, and its molecular formula is (CH2OH)2. The world MEG production capacity for the year 2016 was 34.8 million tons. Some of you who work on cars may have heard of the compound before. Ethylene glycol has a melting point of 197.3 °C. 1. 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. Hence, ethylene glycol is miscible with water. Polyethylene Glycol: The general formula for polyethylene glycol is H−(O−CH2−CH2)n−OH. Over a molecular weight of 900, it can be a white waxy solid, flakes or a powder. Mono-Ethylene Glycol Production Capacity by Region. An automotive antifreeze is a liquid used in the radiator and cooling system of an internal combustion engine for vehicles. 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. In addition, suspension polymerization can also be used. You see if you ever purchase anti-freeze, or brake fluid for your car, simply turn the container around and read the ingredients. To extend this range, other chemicals like ethylene glycol and propylene glycol are added. Ethylene glycol is the main ingredient in many antifreeze mixtures for automobile radiators. Ethylene glycol is a syrupy liquid at room temperature whereas polyethylene glycol is a solid material. Ethylene Glycol และ Polyethylene Glycol มีความแตกต่างกันอย่างไร? Propylene Glocol Vs Ethylene Glycol. Ethylene Glycol: The general formula for ethylene glycol is C2H6O2. This is mainly because A. Absorption of propylene glycol from the gastrointestinal tract is slow. Its’ structure is commonly written as H−(O−CH2−CH2)n−OH. Ethylene glycol is a colorless and odorless alcoholic compound having the chemical formula C2H6O2. A high yield (90%) can be obtained when the reaction occurs at acidic or neutral pH, in the presence of excess amount of water. It has a faint sweet taste. OmniPur Polyethylene Glycol 8,000 - CAS 25322-68-3 - Calbiochem 1 Product Result | Match Criteria: Product Name What is Ethylene Glycol      – Definition, Properties, Uses 2. Polyethylene Oxide should not be called Polyethylene Glycol. Ethylene glycol solutions became available in 1926 and were marketed as “permanent antifreeze” since the higher boiling points provided advantages for summertime use as well as during cold weather. Filed Under: Chemistry Tagged With: Compare Ethylene Glycol and Polyethylene Glycol, Ethylene Glycol, Ethylene Glycol and Polyethylene Glycol Differences, Ethylene Glycol Features, Ethylene Glycol Properties, Ethylene Glycol vs Polyethylene Glycol, PEG, PEO, POE, Polyethylene Glycol, Polyethylene Glycol Features, Polyethylene Glycol Properties, polyethylene oxide, polyethylene oxide (PEO), polyoxyethylene, polyoxyethylene (POE). Polyethylene glycol (PEG) is soluble in water, non-flammable and non-toxic and is a waxy white substance that is solid at room temperature. Polyethylene glycol is, in fact, used in antifreeze because it lowers the freezing temperature of water. Therefore, this molecule is capable of forming hydrogen bonds with water molecules. The two –OH groups are attached to the adjacent carbon atoms. Polyethylene Glycol: Polyethylene glycol has many uses including medical uses, chemical uses, biological uses, industrial uses, etc. Below a molecular weight of 700, it is an opaque liquid. Otherwise known as PEG and PG, these ingredients are found in your car, in your food, in your pharmaceuticals, and (you guessed it) in your personal care products. I want to use ethylene glycol or propylene glycol as an anti-freeze. What is the Difference Between Ethylene Glycol and Polyethylene Glycol      – Comparison of Key Differences, Key Terms: Ethylene Glycol, Hydrogen Bonds, Polydispersity, Polyethylene Glycol, Polymerization. The polymerization mechanism can be cationic or anionic polymerization depending on the type of catalyst. Its molar mass is 62.07 g mol1. Ethylene glycol is moderately toxic if ingested. Ethylene glycol is a sweet tasting syrupy liquid. Figure 2: Molecular Formula of Polyethylene Glycol. It is miscible with water. It is the most commonly available glycol and is commercially produced in large quantities. Although they have nearly similar names, polyethylene glycol and ethylene glycol are very different compounds depending on their chemical structures and general properties. At room temperature and pressure, ethylene glycol is a syrupy liquid. It is an organic compound which can be used as a raw material to  manufacture polyester fibers and antifreeze formulations. The main difference between ethylene glycol and propylene glycol is that ethylene glycol is toxic whereas propylene glycol is moderately toxic. The most common applications of ethylene glycol include its use as a raw material for the production of polyester fibers and as an automotive antifreeze. Although both propylene glycol and ethylene glycol have a large number of applications across a variety of industries and uses including cosmetics and preservatives (propylene glycol) and within the manufacture of resins, inks and polyethylene terephthalate (ethylene glycol) both have a common use within antifreeze and coolant mixes.
