Evaluation of Selected Properties of Modified Sapium Baccatum and Neolamarckia Cadamba

This study was to evaluate the selected performances of modified Ludai (Sapium Baccatum) and Kelempayan (Neolamarckia Cadamba) wood species.  Ludai and Kelempayan were impregnated with acetic anhydride at 80°C, 100°C, and 120°C for 15, 30, 60, 180, 300, and 420 min without catalyst. The highest WPG of 16% and 14% for Ludai and Kelempayan were obtained.  VC% ranging from 0.5% to 10% were obtained.  The ultimate OH-groups substituted of acetylated Ludai and Kelempayan at 120°C were 3.77 mmoles/g and 3.98 mmoles/g, respectively. Unlike the conventional preservative treatment in the industry today, wood-acetyl bonds pose a positive impact on the ecosystem.
