Performances of Ludai (Sapium Baccatum) and Kelempayan (Neolamarckia Cadamba) after Acetylation

Abstract

The study changed the chemicals that make up Ludai (Sapium Baccatum) and Kelempayan (Neolamarckia Cadamba) molecules that have been modified with acetic anhydride. The wood species was treated at 80°C, 100°C, and 120°C.  The changes were assessed by replacing the WPG and OH groups.  The WPG range is 3%–16%, and therefore, at 16%, Ludai had the highest WPG, while Kelempayan had 14%.  At 120°C, a 15% weight per gallon (WPG) solution changed Kelempayan volume by 9%. The Ludai volume changed 5.5% under the same conditions. The Ludai and Kelempayan had the highest OH-substitution rate at 120°C, 3.5–4 mmoles/g.
