Abstract

Extract of cellulose from Gelam wood (Melaleuca leucadendron Linn) has been carried out using methanol and various concentration of hydrochloric acid. Cellulose was characterized using FT-IR spectroscopy. Cellulose from Gelam wood was converted into levulinic acid by F^BW^CUo] as catalyst at 80°C and water as reaction medium. The result showed that cellulose was extracted using 5% (v/v) acid. The product of extraction is similar with cellulose Standard. The yield of Levulinic acid was identified using Gas Chromatography. Conversion of cellulose using HsfBW^O^] as catalyst reached at one hour with levulinic acid 2,6%. Cellulose from Gelam wood can not be converted into levulinic acid due to proton from acid was not destruct the Chemical bond of glycoside in raw starting material.
