A reaction of [3-(2-aminoethylamino)propyl]trimethoxysilane with wood and cellulose – chemical analyses. The paper presents tests results for [3-(2-aminoethylamino)propyl]trimethoxysilane (AATMOS) reactivity with cellulose and Scots pine wood. The tested material was treated with ethanolic solution of aminosilane and analyzed using instrumental methods, including elemental analysis, atomic absorption spectrometry and infrared spectroscopy. The results of the chemical analysis indicated that [3-(2-aminoethylamino)propyl]trimethoxysilane exhibited reactivity with both cellulose and pine wood. In addition, AATMOS-treated cellulose showed a higher content of silicon and nitrogen and more significant changes in FTIR spectra than the treated wood, suggesting that AATMOS showed a higher reactivity to cellulose than to wood.

Organosilanes in wood protection – chemical analysis of wood and cellulose treated with MTMOS. The paper presents the results of methyltrimethoxysilane (MTMOS) reactivity with Scots pine wood and cellulose. The lignocellulosic material after treatment with ethanolic solution of MTMOS was analysed using instrumental methods – atomic absorption spectrometry (AAS) and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). The analysis of silicon concentration in treated material indicated the presence of silane in structure of wood and cellulose. The bands characteristic of vibrations of the silicon-carbon and silicon-oxygen originating from MTMOS molecule were observed in the spectra of modified materials, which confirmed the reactivity of silane with wood and cellulose. Moreover, the chemical analysis indicated that MTMOS exhibited higher reactivity to cellulose than to pine wood.
