Product Description

Introduction
ethylene glycol  is also called ethylene glycol, 1, 2-ethylenediol, or EG. The chemical formula is (CH2OH)2, which is the simplest diol. Ethylene glycol is a colorless, odorless, sweet liquid with low toxicity to animals. Ethylene glycol is miscible with water and acetone, but its solubility is small in ethers. Used as solvent, antifreeze and raw material for polyester synthesis. The polymer polyethylene glycol (PEG) of ethylene glycol is a phase transfer catalyst and is also used in cell fusion; Its nitrate is an explosive.




Chemical property

Due to low molecular weight, active properties, can be esterification, etherification, alcohol, oxidation, acetal, dehydration and other reactions.
Similar to ethanol, it is mainly able to react with inorganic or organic acids to produce esters. Generally, only one hydroxyl group reacts at first. By increasing the temperature and the amount of acid, two hydroxyl groups can form esters. If it reacts with nitric acid mixed with sulfuric acid, dinitrate is formed. An acyl chloride or anhydride readily causes two hydroxyl groups to form esters.
When glycol is heated in the presence of a catalyst (manganese dioxide, alumina, zinc oxide, or sulfuric acid), intramolecular or intermolecular water loss can occur. Glycol can interact with alkali or alkaline earth metals to form alkols.
The metal is usually dissolved in diol, only one alkyd; Glycol disodium and ethylene glycol can be formed by heating the glycol (e.g., glycol monosodium) in a hydrogen stream to 180 ~ 200°C.
In addition, glycol disodium was obtained by heating 2mol sodium methanol with ethylene glycol. Glycol disodium reacts with alkyl halides to form glycol monoether or diether. Glycol disodium reacts with 1, 2-dibromoethane to form dioxane. In addition, glycol is easily oxidized, and depending on the oxidizing agent used or the reaction conditions, various products can be formed, such as glycolal HOCH2CHO, glycolal OHCCHO, glycolic acid HOCH2COOH, HOOCCOOH oxalate, carbon dioxide and water.
Glycol is different from other diols in that its carbon chain can be broken when oxidized by periodate.
Application: Glycol can often be used instead of glycerin.
In the tanning and pharmaceutical industries, they are used as aqueous mixtures and solvents, respectively.
Dinitrate, a derivative of glycol, is an explosive.
The monomethyl ether, or monoethyl ether, of ethylene glycol is a good solvent, such as HOCH2CH2OCH3, for dissolving fibers, resins, paints, and many other organics.
Ethylene glycol has a strong ability to dissolve, but it is prone to metabolic oxidation, resulting in the formation of toxic oxalic acid, so it is not widely used as a solvent.
