What is Ethanediol?

Ethanediol, likewise known as glycol, is the easiest aliphatic dihydric alcohol. It has the chemical properties of alcohols, such as being able to generate ethers as well as esters, being oxidized to produce aldehydes or acids, and also condensing to create ethers. Can additionally be replaced by halogen. Response with acid chloride or acid anhydride normally forms diester. Home heating under the activity of a catalyst (manganese dioxide, aluminum oxide, zinc oxide or sulfuric acid) can dry out intramolecularly or intermolecularly to produce cyclic ethylene glycol acetal, which responds with nitric acid to produce ethylene glycol dinitrate (a type of dynamite). Ethylene glycol is a raw material for the production of polyester resin, alkyd material, and also polyester fiber. It is additionally used as an antifreeze agent for automobiles as well as a refrigerant for aircraft engines. Ester intake is equivalent. Additionally, polymer compounds such as polyester fibers can likewise be synthesized. The mix of ethylene glycol dinitrate and nitroglycerin can reduce the freezing point of dynamites. Ethanediol can also be made use of as a raw material as well as high boiling point solvent for medicines and also plastics. In industry, ethylene is used as basic material, which is first exchanged ethylene oxide and afterwards hydrolyzed to obtain Ethanediol.

Ethanediol Uses

Ethanediol is mainly utilized as a raw material for polyester fibers and is made use of in other polyester resins, unsaturated polyester materials and 1730 polyester paint. Various types of surfactants can be derived from ethylene glycol and polyethylene glycol. Its dinitro substance dinitroethylene glycol is a nitroglycerin.
Ethanediol is primarily utilized in the production of polyester materials, alkyd materials, plasticizers, antifreeze agents, as well as is likewise made use of in cosmetics and nitroglycerins.
Ethanediol is used as analytical reagent, chromatographic reagent and also capacitive medium.
Ethanediol can additionally be used in the manufacturing of other artificial resins, solvents, lubricants, surface area active Representatives, softeners, creams, dynamites, etc. Ethylene glycol can typically be made use of as opposed to glycerin, and is made use of as a hydrating representative and also a solvent in the sun tanning and also pharmaceutical markets, respectively. Ethylene glycol has a strong dissolving capability, however it is quickly metabolized as well as oxidized to create toxic oxalic acid, so it can not be extensively used as a solvent. Including ethylene glycol to the hydraulic liquid can stop the oil-based hydraulic liquid from deteriorating the rubber in the system; the water-based hydraulic liquid with ethylene glycol as the major component is a non-combustible hydraulic fluid, which is utilized in aircrafts and also cars As well as high-temperature molding presses. Ethylene glycol has great deals of crucial derivatives. Minimized molecular weight polyethylene glycol (ethylene glycol, diethylene glycol, triethylene glycol or specifically diethylene glycol, triethylene glycol, tetraethylene glycol) is actually gotten by hydration of ethylene oxide. Diol byproducts. Diethylene glycol can be utilized as a moistening representative, plasticizer, sizing agent, publishing ink solvent, natural gas dehydration desiccant as well as also fragrant hydrocarbon extraction solvent. Diethylene glycol dinitrate looks like ethylene glycol dinitrate and is likewise an important industrial dynamite. High-molecular-weight polyethylene glycols are furthermore useful spin-offs, ranging from colorless transparent thick fluids to waxy solids according to different molecular weights. It is made use of as a lubricating substance, dampness preserving representative, solvent, intermediate in rubber and also food industries, and also similarly made use of in the prep work of cosmetics as well as additionally sustaining agents in the fields of materials in addition to papermaking. There are numerous type of esters of ethylene glycol, which are extensively made use of as solvents. Ethylene glycol esters of long-chain fatty acids have surface-improving houses along with can be used alone or along with surfactants as emulsifiers, stabilizers, dispersants, moistening agents, foaming representatives, as well as additionally suspending agents. Ethylene glycol reacts with urea to create ethylene urea, which is used in the fabric sector. Disodium ethylene glycol reacts with 1,2-dibromoethane to develop dioxane, which is a special solvent. Various oxidizing agents or reaction issues are made use of for ethylene glycol. After oxidation, glycolaldehyde, glyoxal, glycolic acid, oxalic acid, and so on can be obtained.

Production Method of Ethanediol

The preparation of Ethanediol adopts chlorohydrin method, ethylene oxide hydration method and ethylene direct hydration method in industry. Each method has its own characteristics, which are described as follows.
Chlorohydrin method
It is obtained by hydrolyzing chlorohydrin as a raw material in an alkaline medium. The reaction is carried out at 100°C. First, ethylene oxide is generated, and then ethylene glycol is generated by pressurized hydrolysis under a pressure of 1.01MPa.
Ethylene oxide hydration
The ethylene oxide hydration method includes catalytic hydration method and direct hydration method, and the hydration process can be carried out under normal pressure or under pressure. Atmospheric pressure hydration generally uses a small amount of inorganic acid as a catalyst and reacts at 50-70°C.
The molar ratio of ethylene oxide to water in the pressurized hydration method should be higher, more than 1:6, to reduce the side reaction of ether formation. The temperature of the reaction is 150° C., and the pressure is 147kPa. Ethanediol is obtained by hydration.
At present, there is a gas-phase catalytic hydration method, using silver oxide as a catalyst and alumina as a carrier, reacting at 150-240 ° C to generate Ethanediol.
Ethylene direct hydration
Ethylene is oxidized in acetic acid solution in the presence of a catalyst (such as antimony oxide TeO2, palladium catalyst) to generate monoacetate or diacetate, and further hydrolyzed to obtain ethylene glycol. The ethylene oxide hydration method is better in the above several methods, the process is simple, and it is suitable for industrialization.
