Ethylene Glycol
Ethylene glycol Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic Ethylene glycol compound with the formula (CH2OH)2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid.

It was demonstrated that, the supercritical dimethyl carbonate process without any catalysts applied, converted triglycerides to fatty acid methyl esters with glycerol carbonate and citramalic acid as by-products, while free fatty acids were converted to fatty acid methyl esters with glyoxal. After 12 min of reaction at 350 °C/20 MPa, rapeseed oil treated with supercritical dimethyl carbonate reached 94% (w/w) yield of fatty acid methyl ester. The by-products from this process which are glycerol carbonate and citramalic acid are much higher in value than glycerol produced by the conventional process. -

Comparative Study of Ethylene Carbonate-Based Electrolyte Decomposition at Li, Ca, and Al Anode Interfaces Joshua Young,* Peter M
Article Cite This: ACS Appl. Energy Mater. XXXX, XXX, XXX−XXX www.acsaem.org Comparative Study of Ethylene Carbonate-Based Electrolyte Decomposition at Li, Ca, and Al Anode Interfaces Joshua Young,* Peter M. Kulick, Taylor R. Juran, and Manuel Smeu* Department of Physics, Binghamton University, Binghamton, New York 13902, United States *S Supporting Information ABSTRACT: One of the major bottlenecks to the develop- ment of alternatives to existing Li ion battery technology, such as Li metal or multivalent ion (Mg, Ca, Zn, or Al) batteries, has to do with the layer of inorganic and organic compounds that forms at the interface between the metallic anode and electrolyte via solvent and salt decomposition (the solid− electrolyte interphase or SEI). In Li metal batteries the growth of dendrites causes continual formation of new SEI, while in multivalent ion batteries the SEI does not allow for the diffusion of the ions. Finding appropriate electrolytes for such systems and gaining an understanding of SEI formation is therefore critical to the development of secondary Li metal and multivalent ion cells. In this work, we use ab initio molecular dynamics simulations to investigate the initial stages of decomposition of organic electrolytes based on ethylene carbonate (EC) and formation of the SEI on Li, Ca, and Al metal fi fi 2− surfaces. We rst nd that pure EC only decomposes to CO and C2H4O2 species on each type of surface. However, when a salt 2− molecule is introduced to form an electrolyte, a second EC decomposition route resulting in the formation of CO3 and C2H4 begins to occur; furthermore, a variety of different inorganic compounds, depending on the chemical composition of the salt, form on the surfaces. -

Polyhydroxyalkylation of Urea with Ethylene Carbonate and Application of Obtained Products As Components of Polyurethane Foams
http://www.e-polymers.org e-Polymers 2008, no. 166 ISSN 1618-7229 Polyhydroxyalkylation of urea with ethylene carbonate and application of obtained products as components of polyurethane foams Iwona Zarzyka-Niemiec* *Rzeszów University of Technology, Department of Organic Chemistry, Al. Powstańców Warszawy 6, 35-959 Rzeszów, Poland; e-mail: [email protected] (Received: 17 March, 2008; published: 27 December, 2008) Abstract: The reaction between urea and ethylene carbonate occur with partial release of CO2 and partial incorporation of carbonate groups into products. The carbonate groups were found to be attached both to nitrogen of urea and to oxyethylene chain. The most effective catalyst of the synthesis was potassium carbonate. The hydroxyethyl and hydroxyethoxy groups of urea derivatives undergo partial dimerization to form carbamate groups in the products. The products of reaction between urea and ethylene carbonate have good thermal stability, they start to decompose at 200 0C. The obtained products can be used as polyol components for polyurethane foams. Polyurethane foams obtained from hydroxyethoxy derivatives of urea (EC8) are rigid products of low water uptake, good stability of dimensions, low mass loss on 30 days heating at 150 C, enhanced thermal stability and good compressive strength.
