Levulinic acid is one of the most important platform chemicals. It is a keto-acid with two reactive functional groups, a carbonyl and carboxyl group, which makes this molecule suitable for various chemical transformations. Levulinic acid and its derivatives such as levulinate esters, β-acetyl acrylic acid, diphenolic acid, ẟ-amino-LA, 2-methyl-tetrahydrofuran and ϒ-valerolactone are used in personal care, flavors and fragrances, resins and coating, pharmaceuticals, agrochemicals, and organic solvents. Levulinic acid is produced from biomasses such as agricultural residue, forest residues and natural herbaceous plants. Herein, hardwood pulp was decationized with 0.01M HCl Prior to dilute acid hydrolysis to produce LA in a hydrothermal batch reactor. The effects of the major reaction conditions such as temperature (T), time (t) and HCl concentration (CH) on LA yield were studied via central composite design (CCD). Other potential co-products of this reaction include formic acid and furfural. This study will pave the way to the use of lignocellulosic biomass in the biorefinery.
