ABSTRACT:
Wood is beneficiated by treating the wood with an agent capable of forming a borate ester linkage between hydroxyl groups of the cell wall constituents of the wood, and thereafter treating the wood with an aldehyde to effect aldehyde cross-linking of cell wall structural constituents of the wood. Suitable borate ester forming agents include boric acid, lower polyalkyl borate esters, mono- and di-substituted derivatives of boric acid and/or the borate esters, and compounds capable of forming these agents in situ under the prevailing reaction conditions.
