*3.1.2. Hydrogenation of benzoic acid with 5% Ru/C catalyst*

5% Ru/C was an active catalyst as compared to 5% Pd/C. Conversion of benzoic acid at the end of 6 h was found to be 99%. The 5% Ru/C catalyst was found to hydrogenate the carboxylic group along with aromatic ring. The products formed in the reaction are as shown in **Scheme 2**. Under the reaction conditions, the selectivity to cyclohexane carboxylic acid was 70%, while that for cyclohexyl methanol, 30%.
