Abstract: The present invention generally relates to processes for preparation of higher alcohols such as n-butanol from lower alcohols such as ethanol by Guerbet condensation. In some aspects, the present invention relates to improvements in n-butanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of hydrogen to ethanol, mole ratio of acetaldehyde to ethanol, mole ratio of ethyl acetate to ethanol and/or mole ratio of carbon monoxide to ethanol.

Abstract: The present disclosure generally relates to processes for preparation of n-butanol, n-octanol and n-decanol from a reaction mixture comprising ethanoi and n-hexanol by Guerbet condensation. In some aspects, the present disclosure relates to improvements in n-octanol and n-decanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of n-hexanol to ethanol. The present disclosure further generally relates to integrated processes for preparation of n-butanol in a n-butanol reactor from a reaction mixture comprising ethanol and hydrogen to produce a n-butanol product stream by Geurbet condensation comprising n-butanol and n-hexanol and for preparation of n-octanol in a n-octanol reactor from a reaction mixture comprising ethanol, n-hexanol and hydrogen to produce a n-octanol product stream by Geurbet condensation comprising n-butanol, n-hexanol and n-octanol.
