| 中文摘要: |
| 研究了以功能化酸性离子液体为催化剂,甲醛与烯烃Prins缩合反应生成1,3-二噁烷及其衍生物,水解得到1,3-二元醇.对不同结构的离子液体、催化剂用量和反应条件进行了考察.结果表明,该体系具有良好的催化性能,反应可在较温和的条件下进行,实现了高活性和高选择性的目标.产物易分离,催化剂重复使用6次,其催化活性基本不变. |
| 英文摘要: |
| A Prins condensation of formaldehyde with alkene for synthesis of 1,3-dioxane and its derivatives catalyzed by a series of functional acid ionic liquids has been investigated.The influences of different ionic liquids,reactants ratio(mole ratio of alken to formaldehyde),reaction temperation,reaction time were studied.High conversion and selectivity of the desired products were achieved under optimum reaction condition.The produces can be easily separated,the catalyst can be reused for six times without any apparent loss of catalytic activity. |
