Estimation of Epoxides [PDF]

open access: possibleNature, 1949
EPOXIDES occur among the products of the autoxidation of unsaturated fatty acids1 and drying oils2, and it has been suggested that they may be formed as intermediates in certain biological oxidations. Their accurate estimation is therefore a matter of considerable importance.

Oxidation-Resistant, Cost-Effective Epoxide-Modified Polyamine Adsorbents for CO2 Capture from Various Sources Including Air.

ChemSusChem, 2019
CO2 adsorbents based on the reaction of pentaethylenehexamine (PEHA) or tetraethylenepentamine (TEPA) with propylene oxide (PO) were easily prepared in "one pot" by impregnation on a silica support in water.

Probing the correlations between the defects in metal-organic frameworks and their catalytic activity by an epoxide ring-opening reaction.

Chemical Communications, 2016
Seven Zr/Hf-based MOFs with different degrees of defects were obtained by modulating the synthetic conditions. The number of missing linkers in these MOFs was calculated based on potentiometric acid-base titration.

The interaction of cytosolic epoxide hydrolase with chiral epoxides

International Journal of Biochemistry, 1993
1. The kinetic parameters of the cytosolic epoxide hydrolase were examined with two sets of spectrophotometric substrates. The (2S,3S)- and (2R,3R)-enantiomers of 4-nitrophenyl trans-2,3-epoxy-3-phenylpropyl carbonate had a KM of 33 and 68 microns and a Vmax of 16 and 27 mumol/min/mg, respectively.

A quest for polycarbonates provided via sustainable epoxide/CO2 copolymerization processes

, 2017
The present review highlights advances in the copolymerization of carbon dioxide (CO2) and epoxides (oxiranes) to produce polycarbonates. Specifically, focus has been given to epoxide starting materials that have been generated from renewable feedstocks ...

Graphite Epoxide

Journal of the American Chemical Society, 2008
Oxidation of graphite may be carried out by reaction with meta-chloroperoxybenzoic acid to yield graphite epoxide. Scanning tunneling microscopy (STM) showed that the functionalization occurs at the edges rather than on the basal plane of the graphite.
