Objective To optimize the synthesis of substituted tetrahydronaphthalene and investigate the influence of 10% Pd/C catalyst in the synthesis of key intermediate. Methods A parallel test was carried out to compare the catalytic activity of triethyl silicane and the 10% Pd/C catalyst, including the total analysis of experimental result . And orthogonal experimental design was used and the influence of solvent and reactant ratio on the yield were investigated. Results The cost of the 10% Pd/C catalyst was obviously lower than that of triethyl silicane,with high yield, little impurity easy effluent disposal. Orthogonal test confirms that the ratio of reactant and catalystthe was the most significant factor. Conclusion The experiments proved that the optimal preparation procedure was much more available for industrial production using the 10% Pd/C as a catalyst.
