실험 절차

A glass autoclave was filled with 0.022 g of the catalyst HRuCl(CO)(PPh3)3, 0.031 g of triphenylphosphine, 0.005 g of decanoic acid, 3.18 g (24.8 mmol) of 1-butoxybut-2-ene and 1.83 g (24.8 mmol) of n-butanol and stirred for 8 hours under autogeneous pressure at 155° C. Thereafter, 2.2 g (122 mmol) of water were added and stirring was continued for a further hour at 155° C. The reaction mixture was analyzed by means of calibrated gas chromatography. At a conversion of 99%, n-butyraldehyde was obtained with a selectivity of 80% and 1,1-dibutoxybutane with a selectivity of 9%.
