Decay furfurylated wood

Reduction of furfural leads to furfuryl alcohol 63 which can be easily transformed into resins, thus replacing phenol formaldehyde resins (Scheme 21) [115]. A recent apphcation concerns impregnation of wood (furfurylated wood). For instance, high retention of grafted or polymerized furfuryl alcohol improves a variety of properties such as an increased hardness, resistance to microbial decay and insect attack, as well as resistance to chemical degradaticai. Modulus of rupture (MOR), elasticity (MOE), and the dimensional stabihty are also significantly increased.

These tests show that furfuryl resin treatment of wood imparts to it a high degree of decay resistance.
