Title: Process for purifying and colour-stabilizing octanols and decanols prepared by aldolcondensation of aldehydes
IPC: C07C29/74
Filed: 1959-04-02
Abstract: In a process of producing octanols or decanols by subjecting aliphatic aldehydes to the aldol condensation, dehydrating the aldols to obtain unsaturated aldehydes, and hydrogenating the unsaturated aldehydes to produce the desired alcohols, the hydrogenation product is distilled in a fractioning column operated at an absolute pressure below 200 mm. mercury, preferably between 10 and 50 mm., to remove aldehyde-impurities overhead, and the product is finally submitted to a distillation in which the desired purified alcohols are obtained as distillate.  The purified alcohols are suitable for the manufacture of colourless esters for use as plasticizers.  In Example 1, n- and iso-butyraldehyde are reacted together in the presence of aqueous 2% sodium hydroxide solution at 90 to 95 DEG C.  The reaction mixture is distilled from the caustic and salts, and the distillate is hydrogenated in the presence of Raney nickel.  The product is dried by stripping in a packed column, operating with a base temperature of 186 DEG C.  The mixture of dry alcohols is then distilled in a 50-foot column, operating at an absolute pressure of 33 to 35 mm., from which aldehydes are withdrawn overhead.  The alcohols are finally distilled in a packed column; and 2-ethyl-4-methyl-pentanol is obtained as distillate.  This product reacts with phthalic anhydride to give a colourless ester. Example 2 relates to the production of mixed decanols starting from n-valeraldehyde and 2-methylbutyraldehyde.

Decorticating; treatment by damping; treating with air and gases; treating with radiations.- To prevent intermolecular respiration during the steeping of grain for the purpose of softening to obtain a satisfactory separation of the husks from the endosperm in produced flour or bread the steeping liquor is supplied, constantly or intermittently, with finely divided air or oxygen or similarly-acting gases, or the grains are exposed at intervals during the swelling process to the atmophere. The grain may be spaced in a thin layer on travelling endless bands and sprinkled with water or treated with gases. The steeping liquor may be caused to circulate from a reservoir across the steeping grains by a pump, a filter to retain carbon-dioxide being inserted in the circuit and the liquor being enriched with air or oxygen. If air or other gases are introduced into a stationary body of steeping liquor the gas may be passed through a filter to retain volatile substances having valuable odours or taste properties. To prevent diastatic effects during the steeping, substances such as dilute solutions of formaldehyde, lime water, or the like may be added. The Specification as open to inspection under Sect. 91 (3) (a) states that to prevent diastatic effects the grains may be treated also with suitable gases or with light of suitable wave lengths, or the steeping may be done in dark rooms. This subject-matter does not appear in the Specification as accepted. Specification 280,605 is referred to.
