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. Ethylene glycol and propylene glycol are organic compounds. Additionally, lower viscosity means EG-based Type I fluids provide better aerodynamic performance at colder temperatures. Less EG is required to produce the same freezing point as PG. In applications where toxicity is NOT a concern, ethylene glycol is often the heat transfer fluid of choice. Z%�
Examples would be: Breweries, Wineries, and food processing plants. Similarities of propylene glycol and ethylene glycol: Both glycols can typically be expected to last twelve years longer. The most common applications of ethylene glycol include its use as raw material for the production of polyester fibers and as an automotive antifreeze. Ethylene or propylene glycol, to depress the freeze point of the fluid. %%EOF
Vacuum Heat Treatment is a comprehensive introduction and technical resource for vacuum processes and equipment, focusing on subjects that engineers, heat treaters, quality assurance personnel and metallurgists need to know. Can I mix propylene glycol with ethylene glycol? It is generally considered safe.

It freezes at 32°F (0°C) and boils at 212°F (100°C). These organic compounds have important applications depending on the chemical structure of the compound. Ethylene glycol is commonly used in applications where efficiency is important and there is no human or animal contact due to the toxicity of the ethylene glycol chemistry. 2. Propylene Glycol: Propylene glycol is moderately toxic. Visit our privacy 1. By closing this message or continuing to use our site, you agree to the use of cookies. Operationally, EG-based fluids perform better. It can be used as a raw material in the manufacture of polyester fibers and for antifreeze formulations. Yes, they can be mixed.

Ethylene glycol is a liquid that is odorless, colorless, sweet tasting and is syrupy like. Visit our updated, This website requires certain cookies to work and uses other cookies to help you have the best experience. Where low toxicity is desired, we would recommend propylene glycol. Both ethylene glycol and propylene glycol are alcoholic compounds which have two –OH groups per molecule. Propylene glycol, food or technical grade, is used in applications where human or incidental food contact is a concern. 229 0 obj

What is the Difference Between Ethylene Glycol and Propylene Glycol – Comparison of Key Differences, Key Terms: Automotive Antifreeze, Chiral Carbon, Ethylene Glycol, Hygroscopic, Propylene Glycol, Racemic Mixture. Some of the benefits of using Ethylene Glycol is that helps keeping the car’s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer. A lethal dose of ethylene glycol for humans by ingestion is about three ounces (85 grams). This product is safe for use in cosmetics with qualifications.
Propylene Glycol: Propylene Glycol is used as a solvent for intravenous, oral, and topical pharmaceutical preparations. Propylene glycol is less toxic and is considered when toxicity is a concern. Both products are two chemical compounds used as some low temperature heat transfer fluids. PubChem Compound Database, U.S. National Library of Medicine, Available here.

Propylene glycol, food or technical grade, is used in applications where human or incidental food contact is a concern. The boiling point of this liquid is about 198 °C. help you have the best experience while on the site. 1. Propylene glycol is also used to make polyester compounds and as a base for de-icing solutions. By visiting Propylene glycol solutions become considerably more viscous at low temperatures. Question: Should I use ethylene glycol or propylene glycol in my Marine Engine’s Cooling system? Propylene Glycol: The molar mass of Propylene glycol is about 76.10 g/mol. The best source for Mercruiser OEM parts, marine engines, boat & engine An interesting fact about this particular product is that it can be used to create artificial smoke or fog used in firefighting or theatrical productions. Ethylene glycol has two carbon atoms, and propylene glycol has three carbon atoms per molecule. But large amounts can be toxic.
