Golubeva, Maria A. published the artcileSelective production of γ-valerolactone and ethyl valerate from ethyl levulinate using unsupported nickel phosphide, COA of Formula: C7H12O3, the main research area is valerolactone ethyl valerate levulinate nickel phosphide.
Unsupported nickel phosphide catalyst containing Ni2P phase was applied in the hydrodeoxygenation of Et levulinate in ethanol medium for the first time. The obtained catalyst was investigated by XRF, XRD, NH3-TPD, XPS and TEM techniques. γ-Valerolactone and Et valerate were obtained as the hydrodeoxygenation products. Varying the temperature and the reaction time it was possible to obtain these products with high selectivity. γ-Valerolactone was selectively formed at 200-250°C and Et valerate was selectively formed at temperatures of 300-350°C. Increase in reaction time was contributed to Et valerate formation. The highest selectivity of Et valerate was 100% at full Et levulinate conversion at 350°C after 6 h. 100% γ-Valerolactone selectivity was reached at low conversion of Et levulinate. The highest yield of γ-valerolactone reached 41.7% after 6 h of the reaction at 250°C. The selectivity of γ-valerolactone was 86.9% and the conversion of Et levulinate was 48.0%.
Applied Catalysis, A: General published new progress about Deoxidation. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, COA of Formula: C7H12O3.
