摘　　要：α-四氢萘酮是一种重要的有机中间体,全球需求量大且目前国内尚无批量生产厂家。以采用Cr2O3/γ-Al2O3、MCM-41负载钴、四对氯苯基卟啉钴、四苯基钴卟啉、自制的介孔分子筛负载钴、5A分子筛负载钴等几种催化剂为前提条件,对四氢萘酮的合成试验进行分析,结果是自制的介孔分子筛负载钴催化剂效果最好,5A分子筛具有相近效果,催化剂的选择性普遍低,原料四氢化萘对转化率的影响比较大。α-Tetralone is an important organic intermediate,which is in great demand in the world,but China doesn’t have large-scale production.In this paper,taking the Cr2 O3/γ-Al2 O3,MCM-41,cobalt loaded on tetraphenyl porphyrin,cobalt loaded on self-made mesoporous molecular sieve and cobalt loaded on 5 A molecular sieve were used as catalysts to synthesizeα-Tetralone.The results show that the self-made mesoporous molecular sieve loaded on cobalt catalyst has the best effect,5 A molecular sieve supported cobalt catalyst has the similar effect,the selectivity of catalyst is generally low,and the raw material tetrahydronaphthalene has a great influence on the conversion rate.
