1. Sodium (N-acetyl-N-phenylhydroxylamine beta-d-glucosid)uronate was isolated from the urine of rabbits receiving N-acetyl-N-phenylhydroxylamine. 2. Its chemical structure was confirmed by the correspondence of the infrared spectrum of its tri-O-acetyl methyl ester derivative with the tri-O-acetyl methyl ester derivative of an authentic specimen prepared by the Koenigs-Knorr synthesis.

Fatty acid methyl esters, which are used as biodiesel, can be produced by esterification of fatty acids in supercritical methanol. However, a reverse reaction, esters hydrolyzed to regenerate due the presence water, is making it difficult reduce content sufficiently. In this study, oleic was treated methanol at 310 °C/20 MPa with flow-type reactor adding formate improve yield ester. As result, ...

Aqueous emulsion copolymerization of methyl methacrylate (MMA) and 5,6-benzo-2-methylene-1,3-dioxepane (BMDO) leads to stable particles PMMA bearing in-chain ester units that can be cleaved under basic conditions.

This paper presents trends in the high pressure solubility measurements of long chain saturated methyl esters (methyl decanoate, methyl dodecanoate, methyl tetradecanoate, methyl hexadecanoate, methyl octadecanoate and methyl docosanoate) in supercritical ethane between 313 K and 353 K and for mass fractions between 0.65 and 0.018. The data shows generally a linear relationship between the solu...

SnO2 films containing organized mesopores and nanocrystalline frameworks with easily removable surfactant templates were produced electrochemically using interfacial amphiphilic assemblies formed on the working electrode as a template.

Low-temperature ozonation (-78 degrees C) of 2-methyl-1,3-dioxolane (1a) in acetone-d6, methyl acetate, and tert-butyl methyl ether produced both the corresponding acetal hydrotrioxide (3a, ROOOH) and the hemiortho ester (2a, ROH) in molar ratio 1:5. Both intermediates were fully characterized by 1H, 13C, and 17O NMR spectroscopy, and they both decomposed to the corresponding hydroxy ester at h...
