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...

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
Acid chloride can react with water to form carboxylic acids. They can also react with carboxylic acids to form anhydrides, and react with alcohols to form esters. Additionally, they can react with ammonia to form amides. What is the formula of acid chloride?
Formation of pyrazoles from 1,3,4-oxadiazolium salts 1,3,4-Oxadiazolium salts react with ethyl cyanoacetate in the presence of triethylamine to yield 1-substituted 3-aminopyrazole-4-carboxylic esters. An open-chain intermediate has been isolated and a mechanism is proposed involving initia... ...
