中文摘要 | 銅與2,2,6,6-四甲基哌啶-氧基(TEMPO)結合構成了一種新型的氧化催化體系,使用O2氧化5-羥甲基糠醛(HMF),但很少進行研究來研究Cu / TEMPO / O2的氧化HMF轉化為2,5-二甲酰呋喃(DFF)。更重要的是,現有研究採用均質銅物種,很難回收。因此,開發與TEMPO結合的多相Cu催化劑對HMF的氧化至關重要。在此,提出並首次使用銅基金屬有機骨架(MOF)HKUST-1作為具有TEMPO的非均相催化劑,用於在O2存在下將HMF氧化轉化為DFF。儘管TEMPO和HKUST-1分別不能有效地將HMF氧化為DFF,但HKUST-1和TEMPO的組合成功地將HMF轉化為DFF,而沒有副產物。在120°C下反應時間可能短至3小時,以實現> 96%的HMF轉化,選擇性> 99%,產率為96%,這表明HKUST-1 TEMPO O2肯定是有前途且高度HMF轉換為DFF的選擇性。 HKUST-1還可以與TEMPO結合使用,將HMF氧化為DFF。這些結果表明HKUST-1是使用TEMPO作為氧化劑進行HMF轉化的有利多相催化劑 |
英文摘要 | While Cu combined with 2,2,6,6-tetramethylpiperidin-oxyl (TEMPO) constitutes a novel oxidative catalytic system using O2 for oxidation of 5-hydroxymethylfurfural (HMF), few studies have been conducted to investigate Cu/TEMPO/O2 for oxidation of HMF to 2,5-diformylfuran (DFF). More importantly, existing studies employ homogeneous Cu species, which is difficult for recovery; thus it is crucial to develop heterogeneous Cu catalyst incorporated with TEMPO for oxidation of HMF. Herein, a Cu-based metal organic frameworks (MOFs), HKUST-1, is proposed and employed for the first time as a heterogeneous catalyst with TEMPO for oxidative conversion of HMF to DFF in the presence of O2. Although TEMPO and HKUST-1 are ineffective separately for oxidation of HMF to DFF, the combination of HKUST-1 and TEMPO successfully converts HMF to DFF without by-products. The reaction duration could be as short as 3 h at 120°C to achieve > 96% of HMF conversion with a selectivity > 99% and a yield of 96%, demonstrating that this HKUST-1 TEMPO O2 is certainly promising and highly selective for HMF conversion to DFF. HKUST-1 is also reusable for incorporating with TEMPO to oxidize HMF to DFF. These results indicate that HKUST-1 is an advantageous heterogeneous catalyst for HMF conversion using TEMPO as an oxidant catalyst |
