The present invention relates to a method for producing 1-octanol comprising a contact step between ethanol, n-hexanol and two catalysts A and B, wherein catalyst A comprises a metal oxide comprising Ga and a noble metal and catalyst B comprises a metal oxide comprising Cu, Ni or any mixture thereof.

Method for producing 1-octanol

The present invention relates to a process for obtaining 1-octanol which comprises a contact step between ethanol, n-hexanol and a catalyst, wherein said catalyst comprises: i) a metal oxide that comprises the following metals: M1 is at least one bivalent metal selected from Mg, Zn, Cu, Co, Mn, Fe, Ni and Ca; M2 is at least one trivalent metal selected from Al, La, Fe, Cr, Mn, Co, Ni, and Ga; ii) a noble metal selected from Pd, Pt, Ru, Rh and Re; and iii) optionally, comprises V; with the proviso that the catalyst comprises at least V, Ga or any of their combinations.

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.

Process for the preparation of higher alcohols from ethanol and N-hexanol by guerbet condensation

The invention relates to a method for obtaining higher alcohols from lower alcohols with a catalyst that is a metal oxide comprising gallium and a noble metal selected from the list containing Pd, Pt, Ru, Rh and Re.
