| 1. A process for the production of alcohols comprising:
hydroformylating a feedstock comprising at least one olefin in a hydroformylation reactor to form a hydroformylation product
comprising an organic phase;
hydrogenating the hydroformylation product in a series of at least two reactors to produce an alcohol, wherein at least one
of the hydrogenation reactors comprises a catalyst that can be poisoned by sulphur, and
passing water into the product of the first hydrogenation reactor before the product is passed into the second hydrogenation
reactor, wherein substantially all of the water present is dissolved in the organic phase in the second hydrogenation reactor
and wherein the feed to the first hydrogenation reactor has a sulphur content of below 1 ppm by weight and a chlorine content
of below 1 ppm by weight.
