Tylenic glycol can also be a minor component in screen cleaning solutions, along with the main element isopropyl alcohol. Ethylene glycol is used as a preservative for biological samples, especially in high schools, during the deposition period as a suitable substitute for formaldehyde. It is also used as part of the hydraulic fluid used to control oil and gas submarine equipment. Ethylene glycol is used as a protection group in organic synthesis to protect carbonyl compounds such as ketones and aldehydes.

The brief introduction to Diethylene glycol
Due to its high boiling point and water dependence, ethylene glycol is a useful desiccant. Ethylene glycol is widely used to prevent the formation of natural gas chlorides (hydrates) in long-phase multi-phase pipelines that transport natural gas from distant gas fields to a gas processing center. Ethylene glycol can be recovered from natural gas and, after purification, reused as an inhibitor that removes water and mineral salts. Natural gas is dried by ethylene glycol. In this program, ethylene glycol passes through the top of the tower and encounters a mixture of water vapor and hydrocarbon gases. Dry exit from the top of the tower. Glycol and water are separated and glycol is recycled.
Instead of dehydrating, ethylene glycol can also be used to reduce the temperature at which hydrates form. The purity of glycol used to suppress hydrates (monoethylene glycol) is usually about 80%, while the purity of glycol for dehydration (triethylene glycol) is usually 95 to 99%. In addition, the injection rate for hydrate suppression is much lower than the rate of blood circulation in a glycol dry tower. Ethylene glycol disrupts hydrogen when dissolved in water. Pure ethylene glycol cools to about -12 ° C (10.4 ° F), but when mixed with water, the mixture does not crystallize easily and therefore the freezing point of the mixture decreases. Specifically, a mixture of 60% ethylene glycol and 40% water freezes at -45 ° C (-49 ° F). Diethylene glycol behaves similarly.
It is used as an antifreeze for windshields and aircraft. And is used as part of the compounds used to keep tissues and organs at low temperatures. The combination of ethylene glycol and water can also be chemically known as a glycol concentrate / mixture / mixture / solution. However, the boiling point for aqueous ethylene glycol increases uniformly with increasing percentage of ethylene glycol; Thus, the use of ethylene glycol not only reduces the freezing point, but also increases the boiling point so that the operating range of the heat transfer medium extends to both ends of the temperature scale. The increase in boiling temperature is due to the fact that pure ethylene glycol has a much higher boiling point and lower vapor pressure than pure water.
Pure ethylene glycol has a specific heat capacity, about half of which is water; Thus, as protection against freezing and boiling point increases, ethylene glycol reduces the specific heat capacity of the water mixture relative to pure water. A 1: 1 mixture with a mass with a specific heat capacity of about 3140 J / (kg · ° C) (0.75 BTU / (lb · ° F)) is three-quarters of pure water, so there is a need to increase the flow rate in a system compared to Large bubble water in the cooling passages of internal combustion engines seriously inhibits heat flow (flux) from this area.For more information about Diethylene glycol wholesale, visit our site.
