Abstract
The IR absorption band at 5250 cm−1 is used to determine 0–5% water in furfural. The accuracy of the determination is not less than 5%. The method is suitable for any kind of furfural. The analytical results are unaffected by the presence of formic, acetic, and pyromucic acids, and methanol and ethanol.
