摘要

Process for the preparation of higher alcohols from ethanol and N-hexanol by guerbet condensation. The present disclosure relates, in general, to integrated processes for the preparation of N-butanol in an N-butanol reactor from a reaction mixture comprising ethanol and hydrogen to produce a product stream of N-butanol by condensation of guerbet comprising N-butanol and N-hexanol and for the preparation of noctanol in an N-octanol reactor from a reaction mixture comprising ethanol, N-hexanol and hydrogen to produce a product stream of N-octanol by guerbet condensation comprising N-butanol, N-hexanol and N-octanol. A predominant proportion of the N-hexanol contained in the product streams of N-butanol and N-octanol is isolated and recycled into the N-octanol reaction mixture. In some aspects, the present disclosure relates to improvements in the yield and selectivity of N-octanol and N-butanol by the selection of process reaction conditions such as, but not limited to, the molar ratio of N- hexanol with respect to ethanol and the recovery and recycling of N-hexanol.
