| titleOfInvention | A kind of preparation method for the solid catalyst of synthetic propylene carbonate |
| abstract | The invention relates to a preparation method of a solid catalyst used in the process of synthesizing propylene carbonate. The method uses graphene oxide as a carrier, 1,2-dibromoethane and triethylamine as raw materials, and can be obtained by one-step reaction A solid catalyst for the synthesis of propylene carbonate by the cycloaddition reaction of carbon dioxide and propylene oxide. The method is simple to operate, and the obtained solid catalyst can be continuously recycled after simple treatment, has a long service life, is pollution-free, and greatly reduces production costs. When the catalyst is used in the synthesis of propylene carbonate, the catalytic activity is very high, the highest yield of cyclic carbonate can reach 84.2%, and the selectivity is 97.5%. |
