Versuchsvorschrift

In a 20 1 stainless steel autoclave, which had previously been conditioned using 10% strength nitric acid and was equipped with closed circuit heating and an anchor stirrer, 10.0 kg of 1,1,1,4,4,4-hexafluorobutene were heated from 0 to 30 C. over a period of 10 minutes in the presence of 250 g of catalyst (5% by weight of metallic palladium on activated carbon) at a pressure of 20 bar of hydrogen. After reaching this temperature, the hydrogen consumption was compensated for by repeated pressurization with fresh hydrogen at pressures between 20 and 30 bar. After about 2.5 hours the conversion was 87%. 1,1,1,4,4,4-Hexafluorobutane had been formed in a yield of greater than 99% of theory.
