Conversion of glucose and fructose into levulinic acid has been carried out using natural zeolite and bentonite as catalysts. Natural zeolite and bentonite were characterized using X-Ray Diffractometer and FT-IR spectrophotometer before catalytic process. Reaction of glucose and fructose in water medium at 80°C using natural zeolite and bentonit until 10 hours did not produce levulinic acid. T…
