High Cellulose Purity by Acid Hydrolysis Pretreatment on Kenaf Outer Bast

Acid hydrolysis treatment of kenaf outer bast fiber can produce pure cellulose content and hydrolyzed hemicellulose to monosaccharides. The effects various reaction temperatures (110–130 °C), acid concentrations sulfuric (0.25–1.00 N), times (60–120 min) were investigated as the optimum condition gain content. A 1H NMR spectroscopy was used analyze carbohydrate in treatment. results showed that conditions for refer two prospects. First, a higher temperature 130 °C necessary increase hydrolyzes hemicellulose—the high yield produced by 0.25 N with short time 60 min. improve purity cellulose, provided solution 1.00 120 Hemicellulose at almost 100% based on optimal conditions. analysis revealed primary hydrolyze from fiber.
