abstract: Carboxylic acids react with hydroxylamine hydrochloride in the presence of dicyclohexylcarbodi-imide to give the corresponding hydroxamic acid which is developed with iron(III), thus allowing colorimetric determinations on the tenths of a milligram scale. Esters do not react, and acetic acid can be determined in butyl acetate at a concentration of about 0.1%.
