Syntheses of higher alcohols were accomplished in the Fischer circulating apparatus of 4.5-1, capacity, at 350°-425°, 220 atm. pressure, with a volumetric velocity of the order 6,800-8,400 (time of contact, 26.5-29 sec.) and a duration of 1 hr. In all cases 300 ml. of catalyst were used. The mixture of CO and H₂ was taken in the proportion 1:1, as this was found to be best in previous experiments. (See abs. 278.) The best catalyst was found to be 8ZnO.Al(OK)₃·O.1-V₂O₅, which gives 47% of an oily layer with a yield of 225 ml. of oil/hr./m.³ of gas. The total content of alcohol higher than MeOH in the condensate was found to be 35%, along with 60% MeOH. Qualitatively the aqueous condensate consists of: MeOH, EtOH, iso-PrOH, and the oily layer of C₃H₇OH and a mixture of C₄H₉OH, mainly iso-BuOH. 22 refs.
