Abstract
This study evaluated dioctylaminoborate in wood for fungal decay protection Dioctylaminoborate was synthesized by refluxing dioctylamine and boric acid in 1:1 molar ratio in ethanol for 4 h. The product was characterized by proton Nuclear Magnetic Resonance Spectrophotometry (
1H-NMR) and Fourier Transform Infrared Spectrophotometry (FTIR). Dioctylaminoborate prevented decay in loblolly pine (Pinus Teada L.) by the brown rot fungus, Gloeophyllum trabeum (Gt). The leached specimens with chemical retention of 12.6% had weight loss of 1% by Gt. The non-leached specimens with chemical retention of 3.3% had weight loss of 0% by Gt. The control had a weight loss of 51.1% by Gt. Leaching of treated blocks decreased decay resistance to Gt, which required 12.6% to be effective.
