ABSTRACT:
A process for producing an aliphatic or alicyclic aldehyde is disclosed, which process comprises the step of hydrogenating an aliphatic or alicyclic carboxylic acid or a derivative thereof with molecular hydrogen in the presence of a catalyst, wherein the catalyst is a zirconium oxide catalyst which contains chromium as an essential component, has a weakly basic site amount of more than 0.03 mmol/g as determined by a temperature programmed desorption method using carbon dioxide as an adsorbate in which the amount of carbon dioxide desorbed in the temperature range of from 100.degree. to 250.degree. C. is measured, and has pores having a radius of from 20 to 500 .ANG. in an amount of not less than 0.1 cc/g and pores having a radius of from 1,000 to 50,000 .ANG. in an amount of not less than 0.05 cc/g as measured with a mercury porosimeter. Aldehydes can be obtained directly from aliphatic or alicyclic carboxylic acids or derivatives thereof in high yield.
