| titleOfInvention | Manufacture of butyraldehyde and a catalyst therefor |
| abstract | Butyraldehyde is prepared by the catalytic hydrogenation of crotonaldehyde at temperatures between 160 DEG and 250 DEG C. using as catalyst a material obtained by the application to a catalyst support of nickel oxide and copper sulphate, the latter in a proportion of 0.5-5% based on the combined weight of nickel oxide and support, followed by partial reduction at a temperature in the range 160-250 DEG C. Preferably equimolar proportions of hydrogen and crotonaldehyde are used and the hydrogen is diluted by nitrogen, methane or other hydrocarbons. Suitable catalyst supports are, for example, pumice grains, ceramic materials, kieselguhr, silica gel and pumice powder.ALSO:A catalyst for use in the hydrogenation of crotonaldehyde to butyraldehyde is obtained by applying to a support nickel oxide and copper sulphate, the latter in a proportion of 0.5-5% calculated on the combined weight of nickel oxide and support, and partially reducing at a temperature in the range 160-250 DEG C. Suitable supports are pumice grains and powder, ceramic materials, kieselguhr and silica gel. The nickel oxides may be deposited on the carrier support by precipitating them from soluble salts such as nickel nitrate by means of sodium or potassium carbonate or hydroxide or by ammonia and subsequent roasting in a gas containing oxygen. The catalysts may be regenerated by roasting in the presence of an oxygen-containing gas, for example, air, flushing with nitrogen and partially reducing with hydrogen at 180-200 DEG C. |
