| 摘 要：采用醇鋁作為呋喃酚環(huán)合反應催化劑,研究催化劑用量與呋喃酚選擇性的關(guān)系,以及在反應體系中添加或采出醇對反應收率的影響。結果表明,醇鋁在催化單醚合成呋喃酚過(guò)程中,醇鋁中的烷氧基與原料單醚和產(chǎn)物呋喃酚的芳氧基發(fā)生了交換,交換生成的醇與單醚或呋喃酚發(fā)生副反應降低了呋喃酚收率。探討了呋喃酚環(huán)合反應質(zhì)子酸催化機理。 |

| Abstract：The synthesis of furan phenol through cyclization were studied, catalyzed by aluminium alkoxide and the affect of the catalyst weight against the selection of furan phenol and the feeding in or distilling out of the alcohol against the reaction yield of product. It was found that the alkoxy of the aluminium alkoxide can be exchanged to the arkoxy of the raw material or product in the process of reaction. The alcohol producing in the exchange reaction reduces the yield of furan phenol by the further by-react... |
