A process for producing at least one isooctene comprising: (a) obtaining a fermentation broth comprising 1-butanol; (b) separating dry 1-butanol from said fermentation broth to form separate dry 1-butanol; (c) contacting the dry 1-butanol separated from step (b), optionally in the presence of a solvent, with an acid catalyst at a temperature of 100 to 250 degrees Celsius and a pressure of 0.1 MPa to 3.45 MPa to produce a reaction product comprising said isooctene, at least one, and (d) recovering said isooctene, at least one, from said reaction product to obtain at least one recovered isoisote, in which the "dry 1-butanol" It may contain less than 5% water by weight with respect to the total weight of 1-butanol and water. |
