| titleOfInvention | Method for preparing dibenzofuran |
| abstract | The invention relates to a method for preparing dibenzofuran. The method comprises the following steps of: performing hydrodechlorination on 2,4,8-trichlorodibenzofuran in a kettle reactor at a certain temperature under the normal pressure to obtain dibenzofuran; and reacting by taking aromatic hydrocarbon as a solvent and adding sufficient alkali solution and a phase transfer catalyst under the action of a noble metal loaded catalyst under the condition that the reaction temperature is 40-100 DEG C and the hydrogen flow rate is 10-100 mL/min for 0.5-6 hours to synthesize dibenzofuran. The transformation ratio of 2,4,8-trichlorodibenzofuran is 99.96 percent, and the yield of dibenzofuran is 99.57 percent. |
