Synthesis methods of the present invention aluminophosphate molecular sieve (HMA), silica molecular sieve (MCM-41), and aluminophosphate molecular sieve (AlPO 4 -5) made non-uniform by the molecular sieve containing the transition metal-containing catalyst, such as And, under the heterogeneous catalyst prepared by performing a specific washing process after firing it, liquid partial oxidation of tetralin under the optimum reaction conditions, thereby improving the conversion and selectivity of tetralin, especially The present invention relates to a method for preparing tetralon, in which the durability and activity of the catalyst are maintained even when the catalyst is reused by the washing process. |
