Abstract:
The present invention relates to a method for preparing 1,5-dimethyltetralin using a dealuminated zeolite beta catalyst.The preparation method of 1,5-dimethyltetralin according to the present invention has the effects of not only showing high conversion and high selectivity of 1,5-dimethyltetralin but also of suppressing deactivation of a zeolite beta catalyst so as to enhance the catalyst life, by using the dealuminated zeolite beta catalyst.
