Ethylene Glycol is an organic compound with formula (CH2OH)2 and is the simplest member of the alcohol family. It is a colorless, odorless, sweet, viscous liquid with little volatility. Due to its hydroxyl group, it has the typical properties of alcohols and is soluble in water and many organic liquids.
Ethylene Glycol is a chemical that is commonly used in commerce and industry. It is used as a raw material in the production of polyester fibers and is also highly used to produce antifreeze and coolant products. Ethylene Glycol plays a double-action role when it comes to cars; it protects car engines from freezing in the cold of winter and is also used as a coolant for overheating in summer. Other applications include heat transfer fluids, which are used as industrial refrigerants for gas compressors, heating, ventilation and air conditioning systems.
Monoethylene Glycol (MEG)
Monoethylene Glycol (MEG) is the simplest combination of Glycols used to produce these organic compounds from Ethylene raw materials in industry. Monoethylene Glycol is actually one of the most common organic compounds of Ethylene Glycol, which has antifreeze and freezing properties. In fact, the main ingredient in the formulation of antifreeze products is Monoethylene Glycol. If we want to take a look at the physical properties of this chemical compound, we must say that Monoethylene Glycol has a molar mass of 62.5 grams per mole, its melting point is -13 degrees Celsius and its boiling point is 197 °C. This material has a self-igniting point at a temperature of 111 °C.
Applications of Monoethylene Glycol (MEG)
One of the most important applications of Monoethylene Glycol is its use as a raw material for production of polyesters and polyethylene terephthalates.This chemical is also used in the production of car antifreeze. This material is used in air conditioning systems for cooling and heat transfer. Monoethylene Glycol is also used inside chillers and refrigeration equipment in industries to prevent criticism. In fact, this chemical is used in industries where antifreeze products should be produced. Monoethylene Glycol is also used in the production of rubber and various polymer resins.
Diethylene Glycol (DEG)
Diethylene Glycol (DEG) is also one of the types of Ethylene Glycols that is produced by performing several hydrolysis reactions. It has a molar mass of 106 and a melting point of -10.45 °C, a boiling point of 245 °C and a flammability of 227 °C. One of the applications of this chemical compound is the synthesis of some compounds. Diethylene Glycol is used as a raw material for the production of various resins. It is used as a chemical solvent in the oil and paint industry and in the production of cosmetics, creams and lotions, industrial lubricants, gas dehydration, paper industry And is used in the production of various types of adhesives. To maintain and store Diethylene Glycol, it is necessary to pay attention to some very important points. The storage of this chemical should be dry and cool, and this chemical compound should be away from sparks or heat. Warehouses that store Diethylene Glycol must be equipped with a very strong ventilation system. Consumption of large amounts of this substance can cause liver and kidney poisoning and eventually death, so it should not be used as an oral. Consumption of large amounts of this substance can cause liver and kidney poisoning and eventually death, so it should not be used as an oral. Diethylene Glycol is generally classified as a toxic chemical and safety precautions should be taken when using it
Triethylene Glycol (TEG)
Triethylene Glycol is colorless with the ability to absorb moisture from surrounding materials. One of the most important physical properties of Triethylene Glycol is the high solubility of this chemical compound in water. The melting temperature of this material is -7 degrees Celsius and its boiling point is 285 degrees Celsius. The density of this chemical compound is 1.1 g /mol. This chemical is used to produce various resins and in textile industry as an air conditioner and lubricant for many synthetic and natural fibers. This compound is also used in the preparation of antifreeze, synthesis, morphine, corrosion inhibitors and antioxidants
Polyethylene Glycol (PEG)
Another type of Ethylene Glycol is Polyethylene. This substance is used in various industries, the most important of which are the medical and pharmaceutical industries. For example, PolyEthylene Glycol is the base material of many laxatives, so it is used to prepare the patient before surgery. It is also used in many drugs to bind between different compounds. When Polyethylene Glycol binds to protein drugs, it can allow protein to pass slowly through the bloodstream. This chemical is biosafety and does not pose a danger to the body. But some people are sensitive to this substance and we see allergic reactions from them. Therefore these people should make sure not to use drugs containing Polyethylene Glycol.
