【摘要】：以鐵次卟啉二甲酯(Fe Cl DPDME)為模型催化劑,在無任何外加溶劑及助劑的條件下,催化氧氣氧化α-蒎烯,探討了反應(yīng)溫度、反應(yīng)時間、催化劑質(zhì)量分?jǐn)?shù)以及氧氣流速等工藝條件對反應(yīng)的影響,并對Fe卟啉催化烴類分子氧反應(yīng)機(jī)理進(jìn)行初步探討。研究結(jié)果表明:氧化主要發(fā)生在α-蒎烯雙鍵和烯丙位碳?xì)滏I,當(dāng)反應(yīng)溫度為80℃、反應(yīng)時間為6 h、催化劑質(zhì)量分?jǐn)?shù)為50 mg/kg、氧氣流速為60 m L/min時,α-蒎烯轉(zhuǎn)化率及主要氧化產(chǎn)物的選擇性更高,分別達(dá)到17.9%和86.7%。
[Abstract]:The oxidation of 偽 -pinene by oxygen was studied by using FeCl DPDME-FeCl DPDMEas as model catalyst and without any additional solvent and auxiliary agent. The reaction temperature and reaction time were discussed.The effects of catalyst mass fraction and oxygen flow rate on the reaction were investigated. The mechanism of catalytic reaction of hydrocarbon molecular oxygen catalyzed by Fe porphyrin was discussed.The results show that the oxidation occurs mainly in 偽 -pinene double bond and allyl hydrocarbon bond, and the reaction temperature is 80 鈩，
