ethylene glycol vs propylene glycol

Propylene Glycol: Propylene glycol is moderately toxic. 1993; Hilliard, Robinson et al. What are the freezing points of various aqueous solutions of these chemicals? It has a faint sweet taste. Ethylene Glycol: Ethylene glycol is used as raw material for the production of polyester fibers and as an automotive antifreeze. Propylene glycol is also used for it's heat transfer and freeze protection properties. Less EG is required to produce the same freezing point as PG. Ethylene glycol and propylene glycol are organic compounds with alcohol functional groups. Solutions of 50/50 Propylene Glycol/ water (50/50 PG/water) and 50/50 Ethylene Glycol/water (50/50 EG/water) were tested in radiators of different geometries. It is used as a solvent in the pharmaceutical industry. Propylene Glycol: Propylene Glycol is a synthetic organic compound that has the chemical formula C3H8O2. Ingestion of large quantities of ethylene glycol can cause vomiting, coma, respiratory failure, convulsions, metabolic changes, cardiopulmonary effects etc. Both EG and PG are produced from the refining of crude oil and natural gas. The boiling point of this liquid is about 198 °C. 1983; Apple, Googins et al. Catalyst: Both acidic and basic catalysts are used for the production of ethylene glycol. Ethylene glycol has two carbon atoms, and propylene glycol has three carbon atoms per molecule. They make a propylene glycol coolant (vs ethylene glycol most often found) that's very interesting. In the refractometer field of view at the right you can see an area of grey scale and an area of white. Propylene glycol can also interfere with some ethylene glycol assays (Robinson, Scott et al. Between the two ethylene glycol is a better heat transfer fluid than propylene glycol. The main difference between ethylene glycol and propylene glycol is that ethylene glycol is toxic whereas propylene glycol is moderately toxic. For example if a coolant loop or system is being winterized and temperatures will fall down to -10°F at the lowest, a mixture of 30% propylene glycol to 70% water will be enough to protect the system. So when producing in the industry, a racemic mixture is resulting. But large amounts can be toxic. Propylene glycol, food or technical grade, is used in applications where human or incidental food contact is a concern. When a reaction takes place between ethylene oxide with water, the ethylene glycol oligomers or the ethylene glycol, it gives rise to polyethylene glycol. Ethylene glycol is produced when a reaction takes place between the ethylene oxide and water. Boiling point of propylene glycol is 188.2 °C. Her interest areas for writing and research include Biochemistry and Environmental Chemistry. Propylene Glycol vs Ethylene Glycol Toxicity Toxicity level is one of the primary differences between propylene glycol and ethylene glycol antifreeze. “PropyleneGlycol-stickAndBall” By Karlhahn – Own work (Public Domain) via Commons Wikimedia. Ethylene glycol and propylene glycol differ when considering physical, environmental, and heat transfer characteristics. The main difference between ethylene glycol and propylene glycol is that ethylene glycol is toxic whereas propylene glycol is moderately toxic. Propylene glycol is typically used in food processing facilities and applications where there is potential for contamination of potable water or food as it is non-toxic to humans and animals. All rights reserved. People will commonly mistake Propylene glycol for Ethylene glycol, but the contrast is that Ethylene glycol is toxic. It is important that the … However, when considered the uses, both are used for somewhat same purposes. Etilen glikol diproduksi dari etena. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. 3. Compare the Difference Between Similar Terms. It is also used to produce polyester compounds, in smoke machines, in hand sanitizers, in cosmetics, etc. Propylene alcohol serves the main purpose of absorbing water. This category does not contain glycol ethers based on propylene glycol, dipropylene glycol, or tripropylene glycol. It is a viscous liquid. Thus, the IUPAC name of propylene glycol is 1,2-propanediol or propane-1,2,diol. Answer: The freezing points of these glycol solutions can be found in the tables below: The inhalers that I was using for my REACTIVE AIRWAY DISEASE, contained propylene glycol. It produces ethylene glycol when processed. “Ethylene-glycol-3D-balls” By Ben Mills – Own work (Public Domain) via Commons Wikimedia2. It has a chiral carbon (3rd carbon atom), therefore, propylene glycol exists in two stereoisomers. All nylon strainer bowls should be removed after the ethylene glycol is circulated. The specific EG and PG reaction steps utilized in this case study are described in Appendix 5. PubChem Compound Database, U.S. National Library of Medicine, Available here. Freezing Points of Propylene and Ethylene Glycol Solutions. Each hydroxyl group is separately attached to one carbon atom. • So when safer properties are required in industries, ethylene glycol is replaced with propylene glycol. Ethylene Glycol: Ethylene glycol is mainly used for the manufacturing of polyester fibers and as an automotive antifreeze. Its molar mass is 62.07 g mol−1. Ethylene Glycol: The molecular weight of ethylene glycol is about 62.07 g/mol. Printable View « Go Back. Propylene glycol fluids are often selected because of their low acute oral toxicity vs. the moderate acute oral toxicity of ethylene glycols. • Ethylene glycol is more toxic than propylene glycol. 2. However, advanced methods can be used to obtain pure isomer out of the racemic mixture. Propylene glycol, another common coolant, has … Propylene glycol is an additive product and serves many different purposes in a multitude of industries. The main difference between ethylene glycol and propylene glycol is that ethylene glycol is toxic whereas propylene glycol is moderately toxic. Ethylene glycol is an organic compound with two carbon atoms and two hydroxyl groups. It has a faint sweet taste. At room temperature, it is a clear liquid. 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. Ethylene glycol memiliki titik leleh 197,3 ° C.
