摘要：Quaternary ammonium tetraphenylborates (TPBs) and quaternary ammonium tetrafluoroborates were synthesized for the manufacture of leaching-resistant boron wood preservatives. The leachability of these boron compounds and the termite and decay resistance of wood treated with these compounds were evaluated. The boron leaching rate of wood treated with quaternary ammonium TPB formulations ranged from 2.1 to 6.7 percent, while that of quaternary ammonium tetrafluoroborate formulations ranged from 23.3 to 59.0 percent. Quaternary ammonium tetrafluoroborates performed better than quaternary ammonium TPBs in termite resistance and inhibition zone tests. Quaternary ammonium tetrafluoroborates could inhibit Gloeophyllum trabeum and Phanerochaete chrysosporium at all concentrations used in the laboratory inhibition zone test. Weight loss of masson pine (Pinus massoniana) sapwood treated with quaternary ammonium tetrafluoroborate solutions was 1.4 to 2.6 percent (G. trabeum) and 2.5 to 3.8 percent (by Coriolus versicolor) at preservative retentions around 7.0 kg/m(3).
