Abstract
The vapor-phase air oxidation of n-butane was studied with a composite catalyst consisting of cesium salt of 12-molybdophosphoric acid and a vanadium promoter, Cs 2.5H 0.5PMo 12O 40 + 2 VO 2+. The main products were maleic anhydride, acetic acid, acrylic acid, CO, and CO 2. The selectivity to acid was as high as that obtained in the oxidation of 1-butene when the extent of the reaction was low, but it gradually decreased with an increase in the extent of the reaction because of the consecutive oxidation. For a better understanding of the catalytic performance, the activity and the product distribution were also studied for the oxidations of various compounds, such as 1-butene, 1,3-butadiene, furan, methyl ethyl ketone, acetaldehyde, acetic acid, propionic acid, acrylic acid, and maleic anhydride. Distinct differences between the oxidation of n-butane and those of 1-butene and butadiene were observed in the effects of the reaction variables. These differences were explained in terms of the affinity of organic compounds for the catalyst.
