The activity of heterogeneous catalysts based on magnesium and aluminum oxide composites proposed for the oxyethylation of fatty acid methyl esters are considered. Two types of catalysts are investigated: calcinated metal oxide composites and calcinated metal oxide composites activated by manganese. Calcination was carried out in the air and nitrogen atmosphere. The catalysts were characterized by the X-ray analysis and the measurements of specific surface and pores dimensions. The testing synthesis carried out in a 2-liter reactor showed an activity of catalysts. The highest activity was obtained for the catalyst with manganese calcinated in the nitrogen atmosphere.
