摘要： 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. A predominant proportion of the n-hexanol contained in the n-butanol and n-octanol product streams is isolated and recycled to the n-octanol reaction mixture. In some aspects, the present disclosure relates to improvements in n-octanol and n-butanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of n-hexanol to ethanol and recovery and recycle of n-hexanol.
