Versuchsvorschrift

In a tubular reactor, there was packed 10 ml. of a 0.5 wt.% palladium-on-alumina catalyst (manufactured by Nippon Engerhard Co., Ltd.), followed by introduction of a gaseous mixture consisting of 30.5% by volume of carbon monoxide, 2.6% by volume of hydrogen, 1.8% by volume of n-butyl nitrite and 65.1% by volume of nitrogen at a rate of 37.4 l. per hour to subject the gaseous mixture to reaction at a reaction temperature of 120° C. under ambient pressure. According to a gas-chromatographic analysis of the reaction mixture, it was found that n-butyl formate was produced in a space time yield of 95 g./l.-catalyst.hr and small amounts of di-n-butyl oxalate and n-butanol were by-produced.
