More Information
Summary:The invention relates to a method for producing low-odor n-butane by catalytic hydrogenation of a feed mixture. The aim of the invention is to provide such a method, wherein the feed material, in addition to n-butane, n-butene and up to 1 mass % formic acid and/or up to 1 mass % pentanals and/or up to 0.5 mass % pentanols, also comprises carbon monoxide. The aim is achieved by treating the feed mixture in the temperature range of 15 to 120° C. with an aqueous solution of an alkali metal or alkaline earth metal hydroxide in the concentration range of 0.5 to 30 mass % and subsequently subjecting the feed mixture to the catalytic hydrogenation.
