Effect of additions of C/sub 2/-C/sub 4/ alcohols on the catalytic activity of silver in the oxidation of methanol
The authors give the results of a study of the partial oxidation of methanol on a pumice-silver catalyst in the presence of ethyl, isopropyl, and isobutyl alcohol impurities that are contained in the methanol feedstock. The choice of alcohols as the materials of the investigation is related to the fact that in the rectification of the methanol feedstock the recovered methanol-fusel oil-water fraction, containing up to 33% water, 5% ethanol, and up to 13% higher alcohols, is burned, i.e., is irretrievably lost for industry, while this valuable chemical raw material can be used for formaldehyde synthesis. The gaseous reaction products were analyzed for CO, CO/sub 2/, H/sub 2/, and O/sub 2/ contents; the amount of the obtained formaldehyde was determined by the sulfite method, the acidity of the formaldehyde solution was determined titrimetrically, and the content of the unreacted methanol was determined chromatographically. The results of the analysis were used to calculate the yields of formaldehyde and gases and the selectivity as the ratio of the amount of methanol consumed for formaldehyde formation to all the reacted methanol.
