Abstract

217,095. Holzveredelung Ges., and Trenkler, H. R. Dec. 6, 1922. Wood, compressing.-In a process for producing a hard and consolidated wood, the whole or part of the wood-cellulose is converted into hydrocellulose or other hydrated cellulose derivatives by soaking in water to which a mineral acid has been added. For example, a 0.1 per cent solution of sulphuric acid may be used. The product is then exposed to pressure and the heat.
