Diethylene glycol is a colorless, liquid organic compound at room temperature produced by the interaction of ethylene glycol and triethylene glycol. Ethylene glycol and its oligomers are preferable as a starting material instead of water, because they allow the creation of polymers with a low polydispersity (narrow molecular weight distribution). Ethylene Glycol is used to remove water vapor from natural gas. As nouns the difference between ethylene and diethylene is that ethylene is (organic compound) the common name for the organic chemical compound ethene the simplest alkene, a colorless gaseous (at room temperature and pressure) hydrocarbon with the chemical formula c 2 h 4 while diethylene is (organic chemistry|in combination) two ethylene groups in a molecule. Small changes in structure can make a big difference in toxicity – just think of the difference between ethanol and the much more toxic methanol. Alcohol-related intoxications, including methanol, ethylene glycol, diethylene glycol, and propylene glycol, may present with a high anion gap metabolic acidosis, with a decrease in serum bicarbonate and a rise in the osmolality, with an increased serum osmolar gap (i.e., difference between calculated and measured osmolality) (see also Chapter 106). As a result, minor amounts of Diethylene Glycol (DEG) and Triethylene Glycol (TEG) is produced as a byproduct. Hazardous Substances Data Bank (HSDB) 10.2 Metabolism/Metabolites. It is important that the … The information above is not contradictory as there is a big difference between ethylene glycol and diethylene glycol. 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. Diethylene Glycol là gì 4. Glycerol is a specific alcohol containing 3 -OH groups. DEG is not corrosive and has a high flash point of between 309° to 617° Fahrenheit (154° to 325° Celsius) so it can be stored in stainless steel drums and does not easily catch fire. Diethylene glycol is used in the manufacture of unsaturated polyester resins, polyurethanes and plasticizers. The reaction is catalyzed by acidic or basic catalysts. Tóm tắt. When excessive doses are ingested, the typical effects to be expected are diuresis, thirst, loss of appetite, narcosis, hypothermia, kidney failure and death, depending on the severity of exposure. Freezing point being around -10 C it's not effective as a practical antifreeze. - Glucose, fructose and Sugars contain larger numbers of -OH groups but they are not termed as Glycols. Ethylene Glycol là gì? Both have high boiling points, 245 and 290 C., respectively. Diethylene glycol (DEG) is a clear, colorless, odorless liquid with a sweet taste, and is an excellent solvent for water-insoluble chemicals and drugs. Chapman and Hall Combined Chemical Dictionary code number CTX90-I (ethylene glycol) and BGL75-B (diethylene glycol). In this case, the -OH groups on neighboring molecules are "condensed", yielding one molecule of water, and an "O-O" bond between the two molecules. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. In addition, it sometimes functions as a deicing agent for runways and planes. Viscosity: lower: higher: Propylene glycol increases major head loss in the systems.

Diethylene glycol is quite similar to ethylene glycol in toxicity, although without production of oxalic acid. Ethylene Oxide reacts with water to produce Ethylene Glycol and can be explained with a chemical equation: C 2 H 4 O + H 2 O = HO-CH 2 Ch 2-OH. Hence, small amounts may possibly pass unchanged with smoke from a cigaret into the body in addition to anything absorbed from the moist end of the cigaret in the mouth. The substitution of diethylene glycol for glycerin as a hygroscopic agent in industry makes it desirable to compare the toxicity of these two chemicals. However, the polyethylene glycol is a POLYmer, a molecule that is formed from a base molecule (in this case, ethylene glycol), which is the "repeating unit" in the molecule. It is also used in some industrial applications like antifreeze formulations, but in very small amounts. • No significant risk of the ethylene glycols is expected under normal use patterns. Ethylene glycol has superior heat transfer efficiency due to lower viscosity - but more fluid must be circulated to transfer the same amount of energy since Propylene glycol has higher specific heat. However, it is very useful as a chemical and can be found in many household items such as detergents, cosmetics, etc. How can one be so toxic and the other taken orally. Ethylene glycol solutions are normally preferred over Propylene Glycol because of their more desirable physical properties particularly at lower temperature. Propylene glycol is used as a solvent in commercial products as well as a diluent for oral, topical, and intravenous pharmaceutical preparations. Key Difference – Ethylene Glycol vs Diethylene Glycol The key difference between ethylene glycol and diethylene glycol is that an ethylene glycol molecule is an individual molecule whereas diethylene glycol molecule is formed by the combination of two ethylene glycol molecules via an ether bond.
