摘要:A method for direct synthesis of adipic acid (AA) adopting green catalytic oxidation route of cyclohexane (CH) using the bimetallic catalysts is described. The reaction to convert CH into AA in the presence of bimetallic catalyst is carried in an autoclave in the temperature range of 25 to 300° C. The CH conversion was over 21% with AA selectivity of 34% and ca. 63% selectivity of cyclohexanone and cyclohexanol together over Au—Pd/TiO 2 bimetallic catalyst.
