Aldehydes and their derivatives – primary alcohols and esters undergo ketonization in the gas phase in the range of 350-450 oC over multicomponental oxide catalyst – Zr-Mg-Y-O. This method is appropriate for processing mixtures of components. An experimental study was performed on ketonization of methyl esters fractions of waste fats and residuary alcohol fractions originating from industrial installations. In both cases mainly ketone fractions were obtained. During transformation of methyl esters and alcohols total yields of ketones amounted to over 60% and about 75%, respectively. Also, other catalytic systems (i.e. Fe-Si-Cr-K-O and Sn-Ce-Rh-O) can be used for ketonization of both raw materials.
