Hydrogenation of difurfurylideneacetone on a raney nickel catalyst

1.5-Difurylpent-1-en-3-one, 1,5-difurylpentan-3-one, 1,5-ditetrahydrofurylpentan3-one, and l,5-ditetrahydrofuryl-pentan-3-ol were obtained by hydrogenation of difurfuryldieneacetone on a Raney nickel catalyst at 20–65°C and atmospheric pressure. It was established that the hydrogenation of difurfuryldieneacetone is a zero-order reaction with respect to the concentration of the starting compound. The rate constants of the reaction were found; the activation energy found for 20–65°C is 6.2±0.5 kcal/mole.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 462–465, April, 1979.
