Specific heat is a property of substance (the so-called material constant). The inhibitors in Dow glycol-fluids are specially formulated to protect system components against corrosion and scaling that can increase maintenance and operating expense, reduce system efficiency and even lead to system failure. Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. Ethylene Glycol Leaving Temperature Degrees F 30% 40% 50% Capacity Factor Pressure Drop Factor ... Glycol Correction Factors All Heat exchangers experience a capacity loss when the fluid is a higher specific gravity than water. The specific heat of antifreeze varies greatly with temperature and the percent concentration of ethylene glycol (antifreeze). Pure ethylene glycol has a specific heat capacity about one half that of water. They are generally considered safer to use, as propylene glycol isn't as palatable[note 1] and is converted in the body to lactic acid, a normal product of metabolism and exercise. Upon ingestion, ethylene glycol is oxidized to glycolic acid, which is, in turn, oxidized to oxalic acid, which is toxic. Water was removed by azeotropic distillation to shift the equilibrium to the right. Table 2. Ethylene glycol is primarily used in antifreeze formulations (50%) and as a raw material in the manufacture of polyesters such as polyethylene terephthalate (PET) (40%). When calculating mass and volume flow of a substance in heated or cooled systems with high accuracy - the specific heat (= heat capacity) should be corrected according values in the figures and the table below. Some of our calculators and applications let you save application data to your local computer. Ethylene Glycol: HOCH 2CH 2OH CAS Registry Number: 107-21-1 Synonyms: 1, 2-Ethanediol Glycol EG Monoethylene glycol Ethylene glycol is produced from ethylene, via the intermediate ethylene oxide. This means that ethylene glycol (common antifreeze) carries 37% less heat per unit volume. The specific heat for some commonly used liquids and fluids is given in the table below. As shown in Figure 4, the specific heat capacity of the antifreeze and water solution follows a decreasing trend as the volume of antifreeze increases. So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. Propylene Glycol: The molar mass of Propylene glycol is about 76.10 g/mol. In December 2012, US antifreeze manufacturers agreed voluntarily to add a bitter flavoring to all antifreeze that is sold in the consumer market of the US. This makes specific heat for ethylene-glycol to be 2.42/4.20x1.10 = 0.634. The specific heat of ethylene glycol is 2.42 j/g-K. How many joules of heat are needed to raise the temperature of 62.0 g of ethylene glycol from 15.2 degrees Celsius to 40.8 degrees Celsius?
