Aerobic oxidation of aldehydes: selectivity improvement using sequential pulse experimentation in continuous flow microreactor
RSC Advances Pub Date: 2014-10-27 DOI: 10.1039/C4RA12067A
Abstract
The aerobic oxidation of aldehyde was investigated using a continuous flow microreactor under 5 bar of oxygen at room temperature. High-throughput screening of experimental conditions resulted in the development of an improved protocol. The synergistic use of a large range of salts and Mn(II) catalyst was found to be a very efficient catalytic system for selective aldehyde oxidation. Indeed for short residence time (i.e. 6 min.), a quantitative conversion of 2-ethylhexanal was obtained with a selectivity toward carboxylic acid of 98%.
