Analysis of Ethylene Glycol

Alcohol ether and alcohol ether ester products are a kind of oxygen-active product, which mainly includes low-carbon alcohol ethers like ethylene glycol and propylene glycol. Using alcohol ether products and acetic acid to conduct esterification reaction can produce alcohol ether ester products.

The earliest scale development of alcohol ether and alcohol ether ester in China began in the mid 1990s, at that time the main production object was ethylene glycol ether, and the enterprises were mainly located in the South Jiangsu Province. Later, under the guidance of Dow Chemistry Company, the leading manufacturers of alcohol ether products, and domestic scientific research institutes, domestic enterprises began to produce propylene alcohol ether and alcohol ether ester products with lower toxicity and similar physical and chemical properties as glycol ethers.

At present, more than 50% of ethylene glycol ethers are used as solvents in various industrial processes, of which the demand for ethylene glycol monobutyl ethers and acetic esters is the biggest. As for ethylene glycol ether products, the ethylene glycol methyl ether is the basic raw material for synthetic pesticides and the antifreeze additive for military jet aircraft. The 2-(2-Methyloxyethoxy)ethanol is mainly used as an electronic chemical. The 3-(2-Methyloxyethoxy)ethanol is mainly used as a brake fluid material. The glycol ether and its acetic ester are mainly used as protective coatings, dyes, resins, leather and other industrial solvents, and can also be used as cleaning agents for metal and glass. And the ethylene glycol monobutyl ether and its acetic ester have good dispersibility in water and are widely used in water-based coatings.
