| titleOfInvention | Catalyst for converting ethyl levulinate into gamma-valerolactone and preparation method thereof |
| abstract | A catalyst for converting ethyl levulinate into gamma-valerolactone comprises two parts, sulfonic acid functionalized hafnium-metal organic framework material SO 3 H-MOF (Hf) and noble metal Ru nano particles, wherein the content of the noble metal Ru is 0.5-5% by weight of the total weight of the catalyst, and a sulfonic acid group SO 3 The content of H is 0-20% of the total weight of the catalyst. The preparation method comprises the steps of adding hafnium tetrachloride, terephthalic acid and 2-sulfonic acid terephthalic acid monosodium salt into a mixed solution of dimethyl formamide and acetic acid, crystallizing, washing and drying to obtain a sulfonic acid functionalized metal organic framework material SO 3 H-MOF (Hf); RuCl was added dropwise 3 The solution is used for obtaining a catalyst precursor, and the catalyst precursor is subjected to sodium borohydride reduction and hydrochloric acid post-treatment to obtain the catalyst. The catalyst has better catalytic activity, selectivity and reusability when being used for converting ethyl levulinate into gamma-valerolactone. |
