Abstract
Processes for making isobutanol are described. The processes involve a first reaction between methanol and ethanol in the presence of a first catalyst to produce an alcohol mixture containing propanol, isobutanol and n-butanol, and a second reaction between the produced propanol and synthesis gas in the presence of a second catalyst to produce isobutanol. The methanol and ethanol produced in the second reaction are recycled and used in the first reaction, and the unreacted propanol is recycled and used in the second reaction.
