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

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: ^*=–0.20, =0.10 and ^*=–1.1, =1.3 respectively.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1740–1745, August, 1989.
