Wood modified furfuryl alcohol (FA) is characterized by very good mechanical properties, dimensional stability, increased resistance to biotic and atmospheric factors. The products of furfurylation also have a dark colour (golden-brown and brown) and aesthetic appearance. It should be noted ecological aspect of furfurylation of wood. In this process, not used any solvents, heavy metals and other compounds negatively affecting to the natural environment. Modifying agent is furfuryl alcohol obtained from the furfural prepared from renewable raw materials rich in pentosans (eg. sugar cane, corn cobs, wood). The composition of the modifying mixture and the parameters of the furfurylation process must be adapted to the species of wood and the dimensions of modified material.
The aim of study was modification alder and poplar wood with furfuryl alcohol and the addition of maleic anhydride as a catalyst.
Keywords: wood modification, furfuryl alcohol, wood colour, maleic anhydride
