Experiments were conducted using (3-aminopropyl) triethoxysilane (APTES) and alkyd resin in order to improve the reactivity of wood protective preparations with wood. The results presented concern a structural analysis (FTIR, AAS) of modified cellulose and wood, both after chemical reactions with silanes and after water extraction. The FTIR spectrum of pine wood powder was presented after a reaction with organosilane preparations and with the addition of alkyd resin, and then after water extraction. The FTIR analysis detected vibrations of Si-C, Si-O and N-H groups, indicating permanent bonding with the organosilane preparation. The presence of bands at 710 cm-1 (characteristic of vibrations of the silicon bond with an atom of carbon and oxygen) and at 1600-1580 cm-1 (characteristic of deformation vibrations of N–H coming from the amine group) confirmed the reactivity of these preparations with the wood. The results of atomic absorption spectrometry confirmed the stability of the organosilane bonds with the cellulose and the wood.
