The effect of solvent on the course of the consecutive reactions in liquid phase was studied for hydrogenation of 1-octine on a platinum catalyst at 25 °C using a series of 32 solvents. The reaction orders with respect to 1-octine, 1-octene, and hydrogen were determined by measuring the dependence of the initial reaction rates on the initial solute concentrations and on the partial pressure of hydrogen. The rate constants obtained for the hydrogenation stages were successfully correlated with the semiempirical parameters of the solvents.
