Cadmium and Tin Magnetic Nanocatalysts Useful for Biodiesel Production

Magnetic mixed iron/cadmium (ICdO) and iron/tin (ISnO) oxide nanoparticles were used as catalysts in relevant reactions for biodiesel production technologies. These compounds were active for hydrolysis and transesterification of soybean oil as well as esterification of soybean oil fatty acids. In th...

Description
Summary:Magnetic mixed iron/cadmium (ICdO) and iron/tin (ISnO) oxide nanoparticles were used as catalysts in relevant reactions for biodiesel production technologies. These compounds were active for hydrolysis and transesterification of soybean oil as well as esterification of soybean oil fatty acids. In the esterification assisted by ISnO high yields, ca. 84%, were achieved, after 1 h reaction at 200 ºC. The oxide was magnetically recovered and reused four times without loss in its activity, while a loss of activity was observed for ICdO catalyst. ISnO also demonstrated catalytic activity for macauba oil, a highly acidic substrate.
