The name ethylene glycol refers literally to “the glycol made from ethylene.” Its systematic name is ethane-1,2-diol. In the third and fourth quarters of 2014, two ethylene glycol plants in Jubail, Saudi Arabia will conduct overhaul and replace the reactors, which will take two to three months. Ethylene glycol is a chemical commonly used in many commercial and industrial applications including antifreeze and coolant. Eng. In recent years, the production capacity of domestic coal-to-ethylene glycol continues to expand. Sinopec Zhenhai Refining & Chemical will also conduct equipment maintenance for a month in the second quarter for its 650,000 ton glycol plant. – All Rights Reserved.

Ethylene Glycols Technology Robert Fulton Dye 3011 Fairway Drive, Sugar Land, TX 77478, USA Abstract−Ethylene glycol (EG) or monoethylene glycol (MEG), the adduct of ethylene oxide (EO) and water, is the simplest glycol. Already a Chemical Engineering gold or platinum member? another term for diol. By that time, the price of glycol via naphtha will rise sharply and the price of SEG® glycol will keep certain margin with the price of glycol via naphtha. n. short for ethylene glycol. It is the first of a homologous series of three dihydroxy alcohols discussed in this article. Most online reference entries and articles do not have page numbers. These glycols are composed solely of carbon, hydrogen and oxygen. The Oxford Pocket Dictionary of Current English, Ester
The apparent consumption of ethylene glycol was 24 million tons in 2001, and it reached more than 100 million tons in 2011, the annual compound growth rate is approximately 14.6%.
According to recent reports, it is predicted that ethylene glycol will become one of the star products that lead the development of global chemical industry.

The average monthly load of Xinjiang Tianye exceeds 80%. Ethylene glycol, also known as monoethylene glycol (MEG), is a major chemical commodity, widely used in the production of polyethylene terephthalate (PET) bottle-grade resins and polyester fibers. https://www.encyclopedia.com/humanities/dictionaries-thesauruses-pictures-and-press-releases/glycol-0, "glycol It can be found…, This column is based on “Acrylonitrile Production from Propylene,” a report published by Intratec. The commercial route to ethylene glycols in use today involves the noncatalyzed thermal hydrolysis of ethylene oxide in water. According to the preliminary statistics conducted by Beijing Booming HighChem Technology Co., Ltd. As of 2013, China's ethylene glycol production capacity has reached 5.1 million tons, among which, the CTEG production capacity has expanded from 200,000 tons in 2012 to 1.25 million tons in 2013. Korean J. Chem. Ethylene oxide is then reacted with water at high temperature or in the presence of an acid catalyst to produce ethylene glycol. Ethylene glycol (EG) or monoethylene glycol (MEG), the adduct of ethylene oxide (EO) and water, is the simplest glycol. According to recent reports, it is predicted that ethylene glycol will become one of the star products that lead the development of global chemical industry. In the industrial preparation of ethylene glycol, ethylene (IUPAC name: ethene) is oxidized to ethylene oxide (IUPAC name: oxirane) using oxygen and a silver catalyst.
