Thermal degradation of black cherry (Prunus serotina Ehrh.) was conducted in an inert atmosphere at temperatures ranging from 250/sup 0/ to 1000/sup 0/C. The volatiles produced during carbonization were condensed in a liquid nitrogen trap and separated by steam distillation after which they were extracted with ether. This fraction was analyzed by gas-liquid chromatography (GLC) using a 4-mm (inside diameter) by 1.83-m-long glass column packed with 10 percent methyl silicone fluid. The GLC column temperature was programed from 40/sup 0/ to 240/sup 0/C at a rate of 12.5/sup 0/C per minute. Using this GLC temperature program, three chromatograms from each carbonization temperature were obtained and the furfural peak was identified and quantitatively analyzed. As carbonization temperature increased from 250/sup 0/ to 500/sup 0/C, the amount of furfural in the condensate also increased. The condensate chromatograms show that considerably more compounds are formed at temperatures above 320/sup 0/C than at 250/sup 0/C. The chromatograms from the temperature range of 500/sup 0/ to 1000/sup 0/C showed little change in the number of compounds detected. Regression analysis revealed relationships between carbonization temperature, mass of the condensate, and mass of furfural per original mass of wood.
