Abstract
PURPOSE: To obtain a lactone useful as industrial intermediates and solvents selectively, by oxidizing an α, ω-diol in the presence of a Pd or Pt catalyst under mild conditions.
CONSTITUTION: An α, ω-diol of formula I:(R1, R1, and R2 are H, alkyl groups; n is ≥2) having two OH groups bonded with 4 or more C atoms, one of which is a primary alcohol, and at least 4 straight chain carbon atoms, is brought into contact with a molecular oxygen-containing gas in the presence of a Pd or Pt catalyst in an inert solvent at room temperature to 200°C, preferably under pressure, to form a lactone of formula II, e.g. γ-lactone, ε-caprolactone, or δ-valerolactone. 1,4-Butanediol, 1,5-heptanediol, 1,6-hexanediol, etc. may be cited as the compound of formula I.
