Dependence of the directions of hydrolysis of methylcyclopentane on Pd-Al2O3 on the distribution of electron density in the molecule

Abstract

1. Raising the pressure from 10 to 40–50 atm leads to opposite changes in the direction of hydrogenolysis of methylcyclopentane, depending on the catalyst: in experiments with an aluminoplatinum catalyst, the ratios of n-hexane to 2-methylpentane formed, n-hexane to 3-methylpentane, and 3-methylpentane to 2-methylpentane increase, while in the case of an aluminopalladium catalyst these ratios decrease. 2. The results obtained agree with the earlier hypothesis of a dependence of the direction of the hydrogenolysis reaction on the charges of the carbon atoms and charges of the metal atoms contained in the catalyst.
