Reaction Steps
Using the same reaction tube and catalyst as in Example 1, a gaseous mixture consisting of carbon monoxide, ketene, n-hexyl nitrite and nitrogen (55:0.8:6.7:37.5, volume ratio) was introduced into the reaction tube at a rate of 39.6 l./hr. and the reaction was conducted at a temperature of 120° C. under ordinary pressure. After reaction, the reaction product was analyzed by gas chromatography. As the result, it was found that di-n-hexyl malonate was produced at a rate of 24 g/l·(catalyst)·hr. and di-n-hexyl oxalate was produced as a by-product.
