| titleOfInvention | A kind of preparation method of 1,3-cyclohexanedione |
| abstract | The invention relates to the technical field of chemical synthesis, in particular to a preparation method of 1,3-cyclohexanedione. The preparation method of the 1,3-cyclohexanedione comprises the following steps: using 1,3-acetone dicarboxylate and acrylate as raw materials, and performing condensation ring closure under the action of an alkali catalyst to obtain an intermediate; The intermediate is hydrolyzed and decarboxylated to obtain a crude product; the crude product is recrystallized to obtain 1,3-cyclohexanedione. The preparation method of 1,3-cyclohexanedione of the present invention has the advantages of convenient process conditions, simple post-processing operation process, high yield of 90.9%, high reaction selectivity, high production efficiency, high operation safety and pollution. Small, suitable for industrial scale production. |
