The synthesis of aldehydes and ketones by the dehydrogenation of allylic and secondary alcohols using a Raney-Ni-Al(i-OPr) 3-Al 2 O 3 catalyst without hydrogen acceptors is presented. 4. Copper-based nanocatalysts for 2-butanol dehydrogenation: Screening and optimization of preparation parameters by response surface methodology. Contact Us | Preparation of Aldehydes and Ketones (i) By oxidation of alcohols Aldehydes and ketones are generally prepared by oxidation of primary and secondary alcohols, respectively. When benzene is treated with a mixture of HCN and HCl in the presence of AlCl3, and the complex so produced decomposed with water, benzaldehyde is produced.

Alternatively, the thioacetal can be alkylated once more to give a thioketal. This preparation method applies in case of conversion of volatile alcohols to aldehydes.
