| titleOfInvention | Improved manufacture of mixtures of higher fatty alcohols and of their sulphonated derivatives |
| abstract | The liquid-solid mixture of hydrocarbons obtained in the synthesis of benzine from carbon monoxide and hydrogen is oxidized and the fractions consisting of acids, esters and lactones are reduced to alcohols. The latter, which contain about 8 to 18 carbon atoms in the molecule may be sulphonated. Oxygen, ozone, nitrogen oxides and chromic acid are mentioned as oxidizing agents, and manganese, nickel, cobalt, copper, iron, chromium, lead, vanadium or their salts, e.g. soaps, may be used as catalysts. Alkalies and alkaline earths may also be present. In examples: (1) a synthetic benzine obtained by Franz Fischer's process is oxidized by means of air in the presence of a manganese soap and after separation of unoxidized material the product is reduced with hydrogen using a copper-chromite catalyst; (2) the oxidation product of example (1) is esterified with butyl alcohol and reduced with hydrogen; (3) an oxidation product obtained from synthetic benzine is freed from unsaponifiable matter and is reduced; the mixture of alcohols is sulphonated in pyridine with a mixture of chlorsulphonic acid and pyridine, or in ether with chlorsulphonic acid. |
