Catalyst of Cu 1, Cr 4, and K₂CO₃ 4 parts was heated at 490° and the gases passed over it at a pressure of 180 kg. per 3 cm.² at the rate of 200 l. per hr. At the start, 44 cc. fluid per m.³ gas was obtained and at the end of 48 hr., only 19 cc. The concentration of iso-BuOH fell from 37 to 30% in 10 hr. and to 24% of the product in 100 hr. The concentration of MeOH increased with time. The products contained about 10% C:O compounds with a ratio of aldehydes to ketones of 4:1, and 12-16% hydrocarbons.
