Abstract

287,064. Hale, W. J., and Haldeman, W. S. March 12, 1927, [Convention date]. Formic. acetic, propionic, butyric, and other aliphatic acids are produced from the corresponding primary alcohols of boiling-points below 350‹ C. by treating the vapour, which may be diluted with an indifferent gas such as nitrogen, water-vapour or air, with a reduced metal to effect dehydrogenation, and immediately after with the unreduced metal oxide to oxidize the aldehyde to acid. Suitable catalysts are copper, silver, mercury, and noble metals such as gold. A promoter may be used, for instance cuprous oxide containing 1 per cent of silver. In an example, a tower is filled with the last-mentioned catalyst, the temperature being 350‹ C. at the top and 280‹ C. at the bottom. Commercial 80 per cent alcohol is vaporized and passed into the tower upwardly. Reduced metal mav be taken from the bottom of the tower, allowed to oxidize in the air, and returned to the top of the tower where acetic acid vapour escapes.
