| titleOfInvention | Method for synthesizing 1,1,3,4,4, 6-hexamethyltetralin |
| abstract | The invention provides a method for synthesizing 1,1,3,4,4, 6-hexamethyltetralin, which comprises the steps of dropwise adding reaction; the dropwise addition reaction is carried out, the cymene, the 2, 3-dimethyl-1-butene and the hydrogen absorbing agent are mixed and dropwise added into a mixture of the catalyst and the solvent, the yield of the product reaches over 80 percent, the catalyst is recycled and reused on the premise that the yield is ensured and is improved compared with the traditional process, the problems that the wastewater discharge amount is large and the wastewater and waste salt are difficult to treat due to the fact that a large amount of anhydrous aluminum trichloride is used in the traditional process are solved, and the method has the advantages of being small in using amount, high in activity, free of pollution, capable of recycling and reusing the catalyst and the like. |
