Effect of the structure of substituted propargyl and allyl alcohols on the rate of their liquid phase hydrogenation on a Pd-Ru alloy membrane catalyst

Abstract

The rates of hydrogenation of substituted propargyl and allyl alcohols in the liquid phase on a Pd-Ru alloy membrane catalyst are described by a two-parameter Taft equation which takes into account the inductive and steric effects of the substituents. The values of the parameters at 363 K with H2 at atmospheric pressure are: ρ*=−0.20, δ=0.10 and ρ*=−1.1, δ=1.3 respectively.
