Fan, Mengjiao published the artcileSwitching production of γ-valerolactone and 1,4-pentanediol from ethyl levulinate via tailoring alkaline sites of CuMg catalyst and hydrogen solubility in reaction medium, Computed Properties of 539-88-8, the main research area is pentanediol gamma valerolactone production ethyl levulinate copper magnesium catalyst.
γ-Valerolactone (GVL) and 1,4-pentanediol (1,4-PeD) are the biomass-derived chems. with the tunable functionalities, serving as the platform for synthesis other value-added product. In this study, we have demonstrated that the production of GVL and 1,4-PeD from Et levulinate (EL), a product from alcoholysis of biomass, could be switched flexibly via tailoring the copper content and abundance of the basic sites in the CuMg catalyst and the reaction medium, achieving the yields up to 99% and 97.7% under optimal exptl. condition. The production of GVL was favored over the CuMg catalyst with the high Cu content, while the abundant basic sites in the CuMg catalyst were the key for further opening of the furan ring in GVL to form 1,4-PeD. Furthermore, the alc. solvent especially isopropanol with the higher hydrogen solubility also facilitated the production of 1,4-PeD. Water as the reaction medium induced significant sintering of Cu in CuMg catalyst, while the alc. solvent could effectively suppress the aggregation of copper species, maintaining the high catalytic stability.
