新型温控聚醚离子液体的合成及应用
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 3
Abstract
离子液体广泛应用于有机合成,设计并合成了新型聚醚季铵盐离子液体,N-(2-(2-甲氧基乙氧基)乙基)-N,N-二甲基-2-(2-(辛氧基)乙氧基)甲基磺酸铵(IL),通过核磁共振, 质谱,差热分析仪等表征手段确证了其结构与物性。考察了该离子液体与有机溶剂溶解性能,发现该离子液体与环己烷形成具有“高温均相,低温分相”特性的温控两相体系,该体系适用于Rh/TPPTS络合物催化1-辛烯氢甲酰化反应。实验结果表明,在优化的反应条件下,1-辛烯氢甲酰化反应烯烃转化率可达99.3%,醛收率达98.5%;催化剂易分离回收,循环6次活性基本不变。
