Process for the continuous conversion of hydrocarbons. Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. However, this method is considered as one of the best methods for the aldehydes preparation from alcohol because aldehydes cannot further oxidize and there is no risk of formation of carboxylic acid from the conversion of aldehyde. The amine–amide metal–ligand cooperation in cobalt catalyst is suggested to facilitate this transformation. 4502–4503. 2918–2919. Kim, R.J.
