Jori, Popat K. published the artcileEfficient Synthesis of γ-Valerolactone-A Potential Fuel from Biomass Derived Levulinic Acid Using Catalytic Transfer Hydrogenation Over Hf@CCSO3H Catalyst, Category: esters-buliding-blocks, the main research area is levulinic acid transfer hydrogenation valerolactone hafnium carbonaceous catalyst.
A new hafnium based carbonaceous catalyst (Hf@CCSO3H) was prepared by simultaneous carbonization and sulfonation of readily available glucose, followed by incorporation of hafnium metal on the surface of catalyst. The catalyst was well characterized using FT-IR, PXRD, EDX, SEM, 13C CPNMR, XPS and BET anal. The catalytic activity of Hf@CCSO3H was evaluated for synthesis of γ-valerolactone-a potential fuel and green solvent. γ-Valerolactone was synthesized from biomass derived levulinic acid by catalytic transfer hydrogenation using 150 wt% of catalyst at 200°C for 24 h in isopropanol solvent as a hydrogen donor. 100% conversion of levulinic acid was achieved with an excellent yield of 96% with more than 99% selectivity of γ-valerolactone as evident from GC anal. The method developed is simple, efficient and economical.
