Abstract

|
This work is focused on the possibility of marine biomass Codium fragile as renewable resources for production of levulinic acid. In an effort to optimize the reaction conditions of levulinic acid production from Codium fragile, response surface methodology was applied. A total of 18 individual experiments were designed to investigate the effect of reaction temperature, catalyst amount, and reaction time. As a result, 4.26 g/L levulinic acid from Codium fragile was produced in the condition of 160.7oC of reaction temperature, 3.9% of sulfuric acid, and 39.1 min of reaction time. This result will provide the useful information for chemical production from marine resource.
