Embodiment 1
[0021] In a 25 ml autoclave, add 0.1 g of MOF-5, 0.161 g of tetrabutylammonium bromide and 1.16 g of propylene oxide in sequence, seal the autoclave and place it in a heating furnace at 50°C until the temperature is balanced Charge carbon dioxide to 6MPa in the reaction kettle afterwards, after stirring and reacting for 4 hours, cooling, deflation, with n-butanol as internal standard, detect by gas chromatography, utilize conventional internal standard method to calculate, obtain the yield of propylene carbonate The rate is 98%.
Embodiment 2
[0023] Using exactly the same reaction conditions and detection methods as in Example 1, only changing the catalytic system to 0.1 g of MOF-5 and 0.133 g of tetrapropylammonium bromide, the yield of propylene carbonate was 60%.
Embodiment 3
[0025] Adopting the same reaction conditions and detection method as in Example 1, only changing the catalytic system to 0.1 gram of MOF-5 and 0.12 gram of tetrabutylammonium bromide, all the other are the same as in Example 1, and the yield of propylene carbonate is 94 %.
