Abstract Furfurylation is a well-known wood modification technology. This paper studied the effect of tannin addition on
the wood furfurylation. Three kinds of dicarboxylic acids, adipic acid, succinic acid, and tartaric acid, as well as
glyoxal as a comparing agent, were used to catalyse the polymerisation of furanic or tannin-furanic solutions during wood modification. Impregnation of furanic or tannin-furanic solution at a certain concentration into the
wood followed with curing at 103°C for a specific duration was performed for the wood modification. Different
properties of the modified woods like dimensional stability, resistance of treatment to leaching, mechanical properties, decay durability against… More >
