• In the asymmetric (enantioface differentiating) hydrogenation of methyl acetoacetate with modified Raney nickel catalysts, the effects of the modifying pH on the amounts of the modifying reagents adsorbed and the enantioface differentiating abilities of the catalysts were studied using glycolic acid, mandelic acid, and 2-hydroxy-3-phenylpropionic acid as the modifying reagents. The results indicate that the modifying pH governs the adsorption mode of the modifying reagent. Thus, the change in the adsorption mode of the modifying reagent with the change in the modifying pH results in changes in the amount of the modifying reagent adsorbed and in the enantioface differentiating ability of the catalyst.
