Levulinic acid (LA) has been identified as a promising green, biomass derived platform chem. Response surface anal. (RSA) with a four-factor-five-level central composite design (CCD) was applied to optimize the hydrolysis conditions for the conversion of bamboo (Phyllostachys Praecox f. preveynalis) shoot shell (BSS) to LA catalyzed with ionic liquid[C4min]HSO4. The effects of four main reaction parameters including temperature, time, C[C4min]HSO4 (initial [C4mim]HSO4 concentration) and XBSS (initial BSS intake) on the hydrolysis reaction for yield of LA were analyzed. A quadratic equation model for yield of LA was established and fitted to the data with an R2 of 0.9868, and effects of main factors and their corresponding relationships were obtained with RSA. Model validation and results of CCD showed good correspondence between actual and predicted values. The anal. of variance (ANOVA) of the results indicated that the yield of LA in the range studied was significantly (P < 0.05) affected by the four factors. The optimized reaction conditions were as follows: temperature of 145°C, time of 103.8 min, C[C4min]HSO4 of 0.9 mol · L-1 and XBSS of 2.04% (by mass), resp. A high yield [(71 ± 0.41)% (by mol), triplicate experiment] was obtained at the optimum conditions of temperature of 145°C, time of 104 min, C[C4min]HSO4 of 0.9 mol · L-1 and XBSS of 2% (by mass), which obtained from the real experiments, concurred with the model prediction [73.8% (by mol) based on available C6 sugars in BSS or 17.9% (by mass) based on the mass of BSS], indicating that the model was adequate for the hydrolysis process. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Recommanded Product: 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Recommanded Product: 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate
