Abstract
Ethanol and higher alcohols are produced from mixtures of carbon monoxide and hydrogen, under pressure, with or without the addition of methanol, employing as catalysts alkali salts of fatty acids mixed with porous supports, for instance, zinc oxide, pumice, magnesite, silica or such as may be employed as catalysts for the synthesis of methanol, for instance, calcined Smithsonite. Formates, acetates or propionates of potassium, rubidium or caesium, or mixtures thereof, are specified. A temperature of 400 DEG -420 DEG C. and pressure of 250-300 atmospheres may be used. Carbon dioxide produced is removed from the reaction gases by washing with alcohol, for instance, synthetic methanol. An initial mixture of more than two volumes hydrogen to one volume carbon monoxide may be used, but the gases returned to the cycle after washing may contain a smaller proportion of hydrogen. To prevent decomposition of the catalyst, the pressure is increased prior to the increase in temperature. Specification 330,919, [Class 2 (iii), Dyes &c.], is referred to.
