specific heat of ethylene glycol

[31] While prolonged low doses of ethylene glycol show no toxicity, at near lethal doses (≥ 1000 mg/kg per day) ethylene glycol acts as a teratogen. We offer products for the temperature range -60°F to 350°F with pH stability and superior corrosion protection for steel, copper, brass and other metals. investigated the performance of ethylene glycol/copper nanofluids and reported an enhanced heat transfer rate. For a heat transfer system the circulated volume must be increased. This means that ethylene glycol (common antifreeze) carries 37% less heat per unit volume. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Ethylene Glycol was first formulated in the 1850’s and is now commercially produced through a chemical reaction between Ethylene Oxide and a catalyst. Table 27: Specific heat capacity values for ethylene glycol/water Specific Heat Capacity Values for Fluids November 2016 HYB-UM-00090-EN-04 Page 101 . Czysty glikol etylenowy ma pojemność cieplna właściwa o jednej drugiej że z wody. The base fluid consists of a (ethylene glycol + water) mixture at (90:10)% mass ratio. [33], Except where otherwise noted, data are given for materials in their, Pure propylene glycol does not taste bitter, and pure propylene glycol is often used as a food additive, for instance in cake icing and shelf-stable whipped cream. The specific heat for some commonly used liquids and fluids is given in the table below. The specific heat for some commonly used liquids and fluids is given in the table below.

A 27.7 g sample of ethylene glycol (EG, a car radiator coolant) loses 688 J of heat. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics. Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. According to the old program I have from Dow, the specific heat of 30% propylene glycol is:.901 @ 10 F.933 @ 100 F.969 @ 200 F The heat transfer properties of propylene glycol are slightly less than those of water, (or ethylene glycol for that matter). Please note: The list is limited to 20 most important contributors or, if less, a number sufficient to account for 90% of the provenance. 4.2 PHYSICAL AND CHEMICAL PROPERTIES . Availability of DEG will depend on demand for derivatives of the primary product, ethylene glycol, rather than on DEG market requirements. Mono Ethylene Glycol, commonly referred to as Ethylene Glycol Antifreeze but also referred to as Ethane-1,2-diol, MEG, EG and Industrial Glycol. ; The specific heat tells us how difficult it is to heat the given body.Substances with low specific heat change their temperature easily, whereas high ones require much more energy delivered to achieve identical effect.

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 varies with both concentration and temperature. Dow glycol-based fluids include inhibited ethylene glycol (EG) and propylene glycol (PG)-based fluids. Quantity Value Units Method Reference Comment; Δ f H° liquid-501.0 ± 4.1: kJ/mol: Ccb: Knauth and Sabbah, 1990: ALS: Δ f H° liquid-486. Propylene Glycol: The molar mass of Propylene glycol is about 76.10 g/mol. at temperature 70°C, it shows that specific heat capacity of 8ml of ethylene glycol mix with the water has the highest specific heat capacity which is 13.2130 J/g*°C. Triethylene glycol, HO(C 2 H 4 O) 3 H, is a colourless, odourless, non-volatile, and hygroscopic liquid. The specific heat capacity of an antifreeze-water solution as the volume of antifreeze increases (Ethylene Glycol Heat-Transfer Fluid, 2017). Ethylene glycol has desirable thermal properties including a high boiling point, low freezing point, stability over a wide range of temperatures, and high specific heat and thermal conductivity. Ethylene-glycol was the only ethylene-carbonate metabolite detected. It has a specific gravity of 1.115 and a flash point of 110 °C. propylene glycol has the higher specific heat. Ethylene glycol, also called ethane-1,2-diol, the simplest member of the glycol family of organic compounds. ± 3. kJ/mol: Ccb: Gardner and Hussain, 1972: ALS: Δ f … 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%). Uses When engine coolant is a 50/50 mix (by volume) of ethylene-glycol in water, the resulting specific heat of the mixed fluid will be about 0.82. Data All Publications/Website.

Kulacki, U. Kortshagen, S. Garrick, V. Srinivasan, K. Ghosh, R. Mittal. Ethylene glycol is by far the largest volume of the glycol products in a variety of applications. "Based on a rather extensive database, it induces skeletal variations and malformations in rats and mice by all routes of exposure. The 1,3-dioxolane protecting group can thereafter be removed by further acid hydrolysis. J. Chem. The breakpoint in solubility corresponds to a minimal content of 2.5 water molecules per ethylene oxide to complete hydration. Applications. Scott D.
