Abstract

The quality of an oxo alcohol is improved by mixing it with sulphuric acid and separating the alcohol from the resulting mixture. The process is particularly suitable for improving the quality of oxo alcohols containing 7 or more carbon atoms. The process may be applied to crude oxo alcohols but preferably the crude product is previously refined to give an alcohol product boiling over a narrow range of temperature. Generally the amount of sulphuric acid used is 0.001-0.1% by weight of the alcohol although amounts up to 0.8% may be used. The sulphuric acid may be used in concentrated form and the mixture then distilled. Alternatively, the alcohol may be mixed with water and sulphuric acid, the alcohol layer then being separated from the aqueous layer, washed with water and distilled. The aqueous solution of sulphuric acid preferably contains up to 25% by weight of acid. The alcohol is contacted with the sulphuric acid at room temperature or above, e.g. up to 80 DEG C. Reference has been directed by the Comptroller to Specification 874,583.
