Preliminary investigations were carried out aiming at the establishment of relationships between chemical, physical, and mechanical properties of beech wood under the influence of heating in water at 50°C and 100°C at pH values from 2.8 to 8.5 and with heating times up to 25 hours. It was found that heating of beech wood in water at 50°C does not produce remarkable changes in its properties. When green wood was heated at 100°C, insignificant changes in its density, shrinking, and α-cellulose content were observed, whereas a considerable decrease in strength was found when tested in a wet state. It was further observed that on prolonged heating, the reactions of the wood and the solutions used as a heating medium under-went distinct changes, attaining an equivalent value approximating the final pH of the wood.
