Description

Furfural is a colorless to yellow aromatic het erocyclic aldehyde with an almond-like odor. Turns amber on exposure to light and air. Furfural has a characteristic penetrating odor typical of cyclic aldehydes. Furfural is prepared industrially from pentosans that are contained in cereal straws and brans; these materials are previously digested with diluted H2S04, and the formed furfural steam is distilled.
