The article reviews domestic and foreign research on wood modification processes by chemical means, giving its types and basic properties. The published results prove that chemical modification of wood, fully or partially by acetylation and furfurylation, transforms wood species with low strength into new "green" materials with improved qualities and properties increasing water resistance, moisture resistance, thermal resistance, as well as tensile strength. Research to determine the strength properties of wood veneer that has been chemically impregnated with furfurylation and acetylation methods for 24, 48 and 72 hours, followed by drying, has increased the tensile strength along the fibres. However, for the determination of the tensile strength across the fibres, a significant decrease in the tensile strength is observed in relation to the increase in impregnation time.
