A study of the reaction of adenine with ethylene oxide or with ethylene carbonate

Reactive and Functional Polymers, 2002
Abstract 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, 1999
Grand 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, 2015
Abstract 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 ...

Conductivity of dilute and concentrated LiAsF6 solutions in acetonitrile + ethylene carbonate and ethylene carbonate + propylene carbonate mixtures. Some thermodynamic properties of pure acetonitrile + ethylene carbonate mixtures

Journal of Electroanalytical Chemistry, 1994
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, 2015
Ethylene 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.

One-pot synthesis of ethylene trithiocarbonate from ethylene carbonate

Applied Catalysis A: General, 2008
Abstract 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).

Infinite Dilution Activity Coefficients in Ethylene Glycol and Ethylene Carbonate

Journal of Chemical & Engineering Data, 2002
Infinite dilution activity coefficients (γ∞) have been determined by using a gas−liquid chromatography (GLC) technique for benzene, toluene, methanol, ethanol, 2-propanol, and acetaldehyde in ethylene glycol and ethylene carbonate in a range of temperatures from 50 to 110 °C.

Ethylene-carbon monoxide copolymers

1995
The synthesis, properties and applications of ethylene–carbon monoxide (E/CO) copolymers are described. These photodegradable polymers are now used to control plastic litter caused by polyethylene loop carriers for beverage cans which have been reported to entangle and endanger wildlife.

Carbon dioxide and ethylene interactions in tulip bulbs

Physiologia Plantarum, 2002
The effect of CO2 on ethylene‐induced gummosis (secretion of polysaccharides), weight loss and respiration in tulip bulbs (Tulipa gesneriana L.) was investigated. A pretreatment with 1‐MCP prevented these ethylene‐induced effects, indicating that ethylene action must have been directed via the ethylene receptor.

In vivo biocompatibility and biodegradation of poly(ethylene carbonate)

Journal of Controlled Release, 2003
Biodegradation and biocompatibility of poly(ethylene carbonate) (PEC) was examined using an in vivo cage implant system. Exudate analysis showed that PEC and PEC degradation products were biocompatible and induced minimal inflammatory and wound healing responses.
