Abstract

Butyraldehyde is manufactured by a continuous process in which hydrogen is reacted with liquid crotonaldehyde under pressure and at a raised temperature in the presence of an aqueous phase and a hydrogenation catalyst, the liquid crotonaldehyde being introduced simultaneously with the hydrogen and the catalyst, and the catalyst being added as an aqueous suspension. Small quantities of an emulsifying agent may be added and the hydrogen is preferably used in excess. To obtain a good yield the hydrogenation should be conducted at a pH value of between 6.9 and 8.0. The required pH is obtained by the addition of both a carbonate and a hydroxide of an alkali or alkaline earth metal, e.g. of calcium, magnesium, sodium or potassium. Known hydrogenation catalysts may be used, e.g. nickel and cobalt catalysts and copper chromite. They may be supported on carriers, for example, on pumice powder or kieselguhr and may be activated, for example, by Cr2O3, Al2O3, ZnO or SiO2. Suitable emulsifying agents are soap or fatty acid condensation products.
