The catalytic activity of chitosan-containing palladium catalysts in the hydrogenation reaction of n-hex-2-yne was studied. The most active was the catalyst with [Pd]:[chitosan] molar ratio = 1:1.3. The hydrogenation rate on this catalyst was five times higher than that of similar catalyst with [Pd]:[chitosan] ratio = 1:3.3. Modification of the active catalyst with silver resulted in increasing the selectivity of the process for cis-hex-2-ene up to 96%.
