| 中文摘要 | 使用常規加熱（CH）通過催化轉移氫化（CTH）將乙酰丙酸（LA）轉化為γ-戊內酯（GVL）需要較長的反應時間，且產率較低。 微波加熱似乎可以解決這些問題，因為微波可以加快反應速度並提高產量。 在這項研究中，比較了三種典型的催化劑Ru / C，Pt / C和Pd / C，使用MW加熱進行LA轉化。 與CH工藝相比，MW輔助工藝以Ru / C和Pt / C更高的產率顯著提高了LA向GVL的轉化。 儘管高溫和仲醇有利於這些催化劑的LA轉化，但Ru / C似乎是最有效的催化劑，因為它可以在160°C達到100％的LA轉化率，99％的GVL選擇性和99％的GVL收率。 C。 這項研究的結果證實，MW是提高LA轉化率的有前途的過程，Ru / C顯示出最高的催化活性，其次是Pt / C和Pd / C。 |
| 英文摘要 | Conversion of levulinic acid (LA) to γ-valerolactone (GVL) via catalytic transfer hydrogenation (CTH) using conventional heating (CH) involves long reaction times, and low yields. Microwave (MW) heating seems a solution to address these issues as MW accelerates reactions and enhances yields. In this study, three typical catalysts, Ru/C, Pt/C and Pd/C, are compared for LA conversion using MW heating. In comparison to CH processes, MW-assisted processes significantly enhance LA conversion to GVL with higher yields by Ru/C and Pt/C. While elevated temperatures and secondary alcohols are favorable for LA conversion by these catalysts, Ru/C appears as the most effective catalyst as it can reach LA conversion as 100%, selectivity of GVL as 99% and yield of GVL as 99% at 160 °C. The results of this study confirm that MW was a promising process for enhancing LA conversion and Ru/C shows the highest catalytic activity, followed by Pt/C and Pd/C. |
