Thermal modification upgrades non-durable timber without biocides, but the process is still specified as a temperature and time schedule rather than as a set of chemical reactions with known extents. This article reviews the reaction network that operates in the wood cell wall between 160 and 220 °C, namely deacetylation of glucuronoxylan, autocatalytic hydrolysis of glycosidic bonds by the liberated acetic acid, dehydration of pentoses to furfural with subsequent furanic polymerisation, and cleavage followed by recondensation of lignin. It then proposes an experimental programme in which each reaction extent is quantified independently on fast-growing poplar and correlated with accessible hydroxyl concentration, equilibrium moisture content, anti-swelling efficiency and bending strength.
