摘要:Rh/tppts催化的高烯烃水相双相合成反应已在咪唑盐,吡啶盐和三乙胺盐的存在下进行.使用咪唑盐和三乙胺盐时,只要它们的烷基"尾部"不小于c8,就能获得高反应速率.采用辛基"尾部"可实现快速且完全的相分离,以及金属在水相中的非常好保持.研究发现,咪唑盐可提供最高的反应速率增强.阴离子的性质对反应有适度影响.证据表明,添加剂可以作为弱表面活性剂,通过简单地切换搅拌的开关来形成和破坏乳状液.

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
