摘要：The properties of wood can be improved through steam-heat treatment. There are many studies about mechanical properties of steam-heat treated wood, but very few studies are on the aspects of chemical modifications. In this study, FT-IR spectra combined with SD-IR spectra, correlation coefficients and 2D-IR spectra are employed to analyze the chemical modifications of teak (Tectona grandis L.F.) wood during steam-heat treatment under treatment temperatures from 120 degrees C to 220 degrees C at intervals of 20 degrees C. Acetic acid, which is produced during steam-heat treatment, acts as a catalyst of condensation and degradation reactions of wood components. The changes of wood components are more and more intense with increasing the treatment temperature. The sensitivity of wood samples to thermal perturbation rises initially with increasing treatment temperature before falling back. The steam-heat treated wood under 180 degrees C is the most sensitive. (C) 2014 An-Min Huang.
