METHOD FOR PRODUCING TETRALONE BY CATALYTIC OXIDATION OF TETRALIN OVER TRANSITION METAL CONTAINING MOLECULAR SIEVES

摘要

A method for producing tetralone is provided to improve the conversion ratio and selectivity of tetralone by using a heterogeneous catalyst containing transition metals and to maintain the durability and activity of catalyst although the catalyst is reused by a cleaning process. In a method for producing tetralone by performing the oxidation of the liquid portion of tetralin in the presence of a catalyst system and oxidant, the catalytic system is a heterogeneous catalyst containing molecular sieve 99.5~95 mole % and transition metal 0.5~5.0 mole % and the reaction is performed at 20~150 °C for 2~12 hours with a stirring speed of 50~1000 rpm.
