Procedure

Experiment was run in the same manner as in Example 2 except that the composition of the gaseous starting materials was replaced by 30.3% by volume of carbon monoxide, 2.6% by volume of hydrogen, 2.4% by volume of n-butyl nitrite and 65.5% by volume of nitrogen and that the catalyst was replaced by a 1.0 wt.% palladium-on-activated carbon catalyst. As the result, it was found that n-butyl formate was produced in a space time yield of 147 g./l.-catalyst.hr and small amounts of di-n-butyl oxalate and n-butanol were by-produced.
