SUMMARY— Volatiles from anhydrous glucose heated in air at 25OT for 30 min were collected in a trap maintained at the temperature of solid carbon dioxide. A concentrated ether extract of the distillate was shown by gas chromatography to contain at least 100 compounds. Among those identified and heretofore unreported from heated glucose were the gamma lactone of 4‐hydroxy‐2‐pentenoic acid, l‐(2′‐furyl)‐propane‐1,2‐dione (acetylfuroyl), 3‐methylcyclopentane‐1,2‐dione, phenol and methylfuroic acid.
