文摘

A procedure is developed for the gas chromatographic determination of lower aldehydes as dibutoxyalkanes and carboxylic acids as butyl esters by the reaction with tributyl borate in an aqueous medium. Derivatization conditions were optimized. The procedure was used to determine side products in glyoxal synthesized by the catalytic oxidation of ethylene glycol.
