process for producing alcohols, their zurückzuführender nitrogen-containing compounds containing elemental nitrogen from 20 wt. ppm, by hydrocarboxilierung received carbonsäurealkylestern

摘要

A method for preparing carboxylic acid alkylester after products free of nitrogen containing compounds. These after products, free of nitrogen containing compounds, are prepared by: (1) reacting olefins with carbon monoxide and alkanols in the presence of a catalyst system consisting of a cobalt compound and pyridine, non-orthosubstituted alkylpyridines or a mixture of these pyridines at elevated pressures and elevated temperatures to produce carboxylic acid alkylesters containing nitrogenated compounds resulting from the pyridines; (2) hydrogenating the carboxylic acid alkylesters to produce after products which include alcohols; and (3) treating the after products with acid ion exchangers to remove the nitrogenated compounds.
