Impurities in molasses alcohol distilled as (middle boiling point impurities) taken from Ishioka Alcohol Government Factory were examined.Carbonyl compounds of these impurities were separated into several fractions by sodium bisulfite treatment and vacuum distillation and alayzed by thin layer chromatography as 2,4-dinitrophenylhydrazone derivatives. One of them was separated by column chromatography and a yellow brown pillar crystal of C_<22>H_<12>O_4N_4,mp 14.5℃, was obtained.This crystal was identified as 2,4-dinitrophenylhydrazone of cyclopentanone by infrared spectrum analysis and other methods.Cyclopentanone was recognized for the first time as an impurity in molasses alcohol.
