摘要：

Small samples (15-150 mg) of wood and bark from basket willow (Salix viminalis) clone Jorr were pyrolysed at 550 degrees C. Samples from pure wood of European White (Silver) Birch (Betula pendula (alba)) and Norway Spruce (Picea abies) were used as references. The compounds produced during pyrolysis were analysed using gas chromatographic (GC) methods: direct injection with GC/FTIR/FID, direct injection with GC/MS, and pre-concentration with GC/MS. The samples from salix, birch and spruce all produced a range of low molecular weight compounds: aliphatic acids, esters, aldehydes, and ketones as well as furans. Commonly, these samples also formed aromatic compounds: phenol, methyl-phenols, and the guiacol (2-Methoxyphenol) series of compounds. Salix and birch both produced the syringol (2,6-Dimethoxyphenol) series of compounds. Syringol derivatives were not detected from the pyrolysis of spruce. (C) 1999 Elsevier Science Ltd.
