Abstract: | Bimetallic ruthenium-tin catalysts were prepared using the sol-gel method and the method of carrier impregnation. Two different
procedures were used for their reduction — reduction in hydrogen atmosphere under an increased temperature, and reduction
using an aqueous solution of sodium borohydride. Hydrogenation of 3-phenylpropenal (cinnamaldehyde) in tetrahydrofuran at
433 K and the total pressure 7 MPa was used as the model reaction for comparing the catalytic properties of the prepared catalysts.
It was demonstrated that a tin addition notably affected catalytic properties of ruthenium in the sense of a selectivity increment
related to the production of an unsaturated alcohol. |
