标题:Gas-Phase Epoxidation Of 3,3,3-Trifluoropropylene Over Au/cutio2 Catalysts With N2O As The Oxidant
摘要:Gas-Phase Epoxidation Of 3,3,3-Trifluoropropylene (Tfp) Was Conducted On A Series Of Au/cutio2 Catalysts With Different Cu Contents With N2O As The Oxidant. These Catalysts Were Effective For This Reaction. The Best Catalytic Performance Was Obtained On A Catalyst Containing 4.6 Wt.% Of Au And 0.9 Wt.% Of Cu (4.6Au/0.9Cu Tio2),With A Steady-State 3,3,3-Trifluoropropylene Oxide (Tfpo) Formation Rate Of 72.4 G(Tfpo) H(-1) Kg(Cat)(-1)Which Was Much Higher Than That On A 2.1Au/tio2 Catalyst (22.1 G(Tfpo) H(-1) Kg(Cat)(-1))The Enhancement Was Attributed To The Higher Au Content In The Cu-Promoted Catalyst And Small Au Particle Size And More Importantly To The Complicated Synergy Between The Au Cu Tio2 Interaction Which Might Be The Active Sites For Epoxidation. Also,High Selectivity To Tfpo Up To 88% Was Obtained On The Cupromoted Catalyst,Due To The Proper Electronic Structure Induced By The Interaction Between Au And Low Valent Cu Species. Catalyst Deactivation Was Due To The Significant Growth Of Au Particles And Loss Of Au Cu Tio2 Interface Because Of The Segregation Of Cu Species During The Reaction. (C) 2014 Elsevier Inc.

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.
