A process for preparing a C13-alcohol mixture comprises
- a) bringing a butene-containing C4-hydrocarbon stream containing
less than 5% by weight, based on the butene fraction, of isobutene into contact
with a nickel-containing heterogeneous catalyst at elevated temperature,
- b) isolating a C12-olefin fraction from the reaction mixture,
- c) hydroformylating the C12-olefin fraction by reaction with
carbon monoxide and hydrogen in the presence of a cobalt catalyst and
- d) hydrogenating the product from c).
The alcohol mixture is suitable for preparing surfactants by alkoxylation, glycosidation,
sulfation, phosphation, alkoxylation and subsequent sulfation or alkoxylation and
subsequent phosphation.
