carboxylic acidp-nitrophenacyl estersp-Nitrophenacyl esters derived from p-nitrophenacyl bromide and carboxylic acids were determined by high-performance liquid chromatography with electron spin resonance. p-Nitrophenacyl bromide was used as the pre-column reagent to determine the carboxylic acids. The ...

The formation of carboxylic acids and dimer esters from ??-pinene oxidation was investigated in a smog chamber and in ambient aerosol samples collected during the Biosphere Effects on Aerosols and Photochemistry Experiment (BEARPEX). Chamber experiments of ??-pinene ozonolysis in dry air and at low...
摘要: Aqueous solutions of CO2 containing tetramethylammonium chloride were photolysed with visible light in the presence of colloidal CdS to yield glyoxylic acid as well as formic and acetic acids and CH2O.关键词: oxocarboxylic acids and esters (acyclic compounds photochemistry, radiation chemistry, ...
Chiral phenolic esters of mesogenic carboxylic acids and their use as admixture in liquid crystal phases The new esters derived from a chiral compound containing two OH groups and at least one mesogenic carboxylic acid which have the general formula (I) ##STR1## in which X.sup.1 =O--H ...
Transportation fuels and chemicals can be produced renewably by selectively altering the carbon skeleton of biomass-derived glucose. The predominantly cata
The application of natural deep eutectic solvents (NADES) in the pharmaceutical, agricultural, and food industries represents one of the fastest growing fields of green chemistry, as these mixtures can potentially replace traditional organic solvents. Th
