Hydrothermal conversion of ethylene carbonate to ethylene glycol
International Journal of Hydrogen Energy, 2016Abstract A novel process for the conversion of ethylene carbonate (EC) to ethylene glycol (EG) in high temperature water was investigated. As a result, even there is no external catalyst and additive, the reaction of EC proceeded well and provided the desired EG in 99% yield with 25% water filling at 250 °C for 2 h. Moreover, only CO 2 as by-product

One-pot synthesis of ethylene trithiocarbonate from ethylene carbonate
Applied Catalysis A: General, 2008Abstract Ethylene trithiocarbonate (ETTC) was synthesized in good to excellent yields and selectivities from a one-pot catalytic reaction of ethylene carbonate (EC) and CS 2 in the presence of a lithium halide by using EC as a source of ethylene oxide (EO).

Abstract Despite recent progress in the coal‐to‐ethylene glycol (EG) technology, some indicators show that the obtained products are still different from those produced by the petroleum route method. Therefore, it is of great significance to improve the thermodynamic performance of the system to obtain an enhanced process technology ...

A study of the reaction of adenine with ethylene oxide or with ethylene carbonate
Reactive and Functional Polymers, 2002Abstract A study on the reaction of adenine with ethylene oxide or with ethylene carbonate at different molar ratios of reagents is described. For both pairs of reagents, nominally, the same products were obtained. At first, N(9)-2-hydroxyethyl derivative of adenine was obtained, and then, polyetherols containing purine rings.

Ethylene Physisorption on Amorphous Carbon
Langmuir, 1999Grand Canonical Monte Carlo simulations of ethylene physisorption on amorphous carbon are studied at temperatures between 150 and 300 K. Ethylene molecules are described as a set of 6 Lennard−Jones interaction sites and the quadrupole moment is taken into consideration to calculate lateral interactions. The cross-sectional area and average orientations

Organocatalytic polymerization of ethylene carbonate
Materials Today Communications, 2015Abstract Organocatalytic polymerization of ethylene carbonate ( EC ) with 3-phenyl-1-propanol ( 3PP ) or triethylene glycol ( TEG ) as initiator and 1,5,7-triazabicyclo[4.4.0]dec-ene ( TBD ) as catalyst using a mono-mode microwave reactor results in poly(ether carbonate) s with M n (GPC) values between 2200 and 3100 g/mol and a ratio of ethylene ...

The specific conductivity κ of LiAsF6 solutions in equimolar acetonitrile + ethylene carbonate and ethylene carbonate + propylene carbonate mixtures was determined at 25°C. The values of the density d, dynamic viscosity coefficient η and dielectric constant D of pure equimolar mixtures of acetonitrile (AN) with ethylene carbonate (EC) and of EC with ...

Models of Ion Solvation Thermodynamics in Ethylene Carbonate and Propylene Carbonate
The Journal of Physical Chemistry B, 2015Ethylene carbonate (EC) and propylene carbonate (PC) are organic solvents used extensively in energy storage applications such as lithium-ion batteries and supercapacitors. Using statistical mechanical theory and computer simulations, this paper compares and contrasts the thermodynamics of ion solvation in EC and PC with the behavior observed in water.
