| titleOfInvention | Preparation method of hexanediol |
| abstract | The application discloses a preparation method of hexanediol, which comprises the following steps: carrying out oxidation reaction on the mixed solution containing cyclohexene and the mixed gas containing ozone under the reaction condition to obtain adipic dialdehyde; wherein the reaction conditions comprise a molecular sieve supported metal oxide as a catalyst. The invention adopts ozone as an oxidant, and a metal oxide loaded by a molecular sieve as a catalyst, and the cyclohexene is oxidized with high selectivity to produce the hexanedial, thereby overcoming the defect that a noble metal complex and sodium periodate are required to be used in the cyclohexene oxidation reaction. Therefore, the invention not only has innovativeness, but also has economic advantages and industrial application prospects. |
