| titleOfInvention | The preparation method of support type bi-quaternary ammonium salt catalyst and preparation method thereof and cyclic carbonate |
| abstract | A kind of support type bi-quaternary ammonium salt catalyst of the present invention, formula (1) is bonded with the carrier of the support type bi-quaternary ammonium salt catalyst The bi-quaternary ammonium salt of expression.The present invention also provides a kind of preparation method of support type bi-quaternary ammonium salt catalyst and its obtained support type bi-quaternary ammonium salt catalyst.The present invention also provides a kind of using preparation method of the above-mentioned support type bi-quaternary ammonium salt catalyst as the cyclic carbonate of catalyst, and the cyclic carbonate is by formula (2) Represent.Catalyst preparation process is simple, and yield is high, and the problems such as overcoming common catalyst to be difficult to separate and need addition co-catalyst, and catalyst has preferable stability and service life cycleï¼›Using catalyst of the catalyst provided by the invention as coupled reaction between carbon dioxide and epoxides, cyclic carbonate can be prepared with higher yields, more with high selectivity. |
