| titleOfInvention | Preparation method of tetrahydrofuran-3-ketone compound |
| abstract | The invention discloses a preparation method of a tetrahydrofuran-3-ketone compound. The preparation method comprises the following steps: adding a 2-butyne-1,4-diol compound in a sulfuric acid aqueous solution; and successively carrying out dehydration reaction and hydration reaction through ceric sulfate catalysis so as to obtain the tetrahydrofuran-3-ketone compound. The method is simple in process, easy to control in condition, low in production cost, high in yield, less in three wastes and environmentally-friendly, a catalyst can be reclaimed and reused, and wastes are nearly not discharged, thus the preparation method in the invention has high industrial prospect and economic benefits. |
