Versuchsvorschrift

A glass autoclave was filled with 0.10 g of the heterogeneous catalyst palladium on active carbon (10% by weight of Pd), 3.0 g (24 mmol) of 1-butoxybut-2-ene and 1.73 g (24 mmol) of n-butanol. After 16 hours at 150° C. under a hydrogen atmosphere (1 bar), the reaction mixture was analyzed by means of calibrated gas chromatography. At a conversion of 21%, 1,1-dibutoxybutane was formed with a selectivity of 42%, dibutyl ether with a selectivity of 25% and 1-butoxybut-1-ene with a selectivity of 22%.
