Abstract

original image

Esterrific and ketonderful! Mixtures of acids and esters, produced by esterification reactions with alcohols in bio-oils, can be upgraded to larger ketones by ketonization reactions using a ceria–zirconia catalyst, on which acids adsorb more strongly than esters, leading to the preferential ketonization of acids followed by ketonization of esters at higher conversions.
