  • Publication number: 20240343884
    Abstract: The present invention relates to a novel integrated process to extract and purify levulinic acid (LA) produced from the technical lignin waste (2-G residue) generated after second generation (2-G) ethanol production from biomass. In this process, liquid-liquid extraction was carried out using fusel oil as an organic extractant to yield a LA rich organic phase and an acidic aqueous phase (raffinate). In addition, selected amines improved the LA yields by acting synergistically. Further fractional distillation was carried out to purify LA. The acidic raffinate is recycled back to the reaction in multiple times, which reduce the use of additional catalyst and make the overall process cost effective. The process is very simple and suitable to remove any colour and humins (soluble tar), which would otherwise form a problem in subsequent process step, particularly in distillation. At optimized process conditions 95% LA is recovered with 98% purity.
