Monoethylene glycol (MEG) accounts for more than 90% of the market for EG. This chemistry permits ethylene glycol to act as an intermediate in a wide range of reactions. The enzyme metabolizes both endogenous substrates, such as ethanol, acetone, and acetal, as well as exogenous substrates including benzene, carbon tetrachloride, ethylene glycol, and nitrosamines which are premutagens found in cigarette smoke. Application Ethylene glycol can be used as a reagent in cyclocondensation reactions with aldehydes and ketones to form 1,3-dioxolanes. It is miscible with water and soluble in ethanol, acetone, acetic acid, glycerine, pyridine, and aldehydes. Ethylene glycol (EG) production via coal-based syngas has been demonstrated to be an attractive process with a higher conversion and lower energy consumption. Indirect CO 2 conversion to ethylene glycol (EG) and methanol (ME) via CO 2-derived ethylene carbonate (EC) as the intermediate is an attractive and promising approach.Cu-Based catalysts have been regarded as effective catalysts for the hydrogenation of EC to yield ME and EG. Ethylene glycol (C2H6O2) is a thick, non-volatile liquid diol that is produced from ethylene oxide. In 1995, their production volumes ranked them among the top twenty organic chemicals in the United States. Ethylene is oxidized to produce ethylene oxide, a key raw material in the production of surfactants and detergents by ethoxylation. 3.

Ethylene oxide (EO) and ethylene glycol (EG) are widely used industrial organic intermediates. Coca-Cola has used biobased ethylene glycol to make its PlantBottle since 2009. Ethylene glycol and propylene glycol are organic compounds. In this work, we prepared Cu/SiO 2 catalysts through different methods for the hydrogenation of EC to yield ME and EG. Since ethylene glycol is produced in relatively high purity, differences in quality are not expected. Other products of ethylene oxide. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. Ethylene glycol ethers are part of brake fluids, detergents, solvents, lacquers and paints. The respective halflives were 0.25 and 2 hours. From Wikipedia.
