ResumoSUMMARY Hard‐maple sawdust was sifted on a con‐trolled‐temperature hotplate for smoke production. The acids, total phenols, and carbonyl compounds were determined on the steam‐volatile and non‐steam‐volatile portions of both whole smoke and the vapor phase. Most of the compounds in these groups were found to be steam‐volatile. Several steam‐volatile monocarboxylic acids and monocarbonyl compounds were isolated and identified from smoke. The C 1 –C 10 acids were found to be present in whole smoke, with the C 1 –C 10 acids occurring in the greatest concentrations. Only C 1 –C 10 acids were found in the vapor phase of the smoke. The following monocarbonyls were identified in the steam‐volatile portion of whole smoke: 2‐pentanone, valeraldehyde, 2‐butanone, butanal, acetone, propanal, crotonaldehyde, and ethanal. In addition, tentative identification of isovalderaldehyde and methanal was made on the basis of a comparison of chromatographic behavior and absorption spectra of the known and unknown compounds.
