Abstract

1450042 Alkanesulphonates UNILEVER Ltd 5 Sept 1973 [6 Sept 1972] 41246/72 Heading C2C A method of preparing alkane sulphonates by reacting an olefin, preferably an alpha-olefin, having a carbon chain length of from 8 to 20 with bisulphite ions in a liquid medium in the presence of a substance known to initiate said reaction, comprises the steps of: (i) forming a mixture of olefin and a co-solvent consisting of water and a short chain alcohol containing from 1 to 4 carbon atoms wherein the alcohol forms from 47% to 70% by weight of the co-solvent and the alcohol is present in an amount of from 50% to 100% by weight of the olefin, and (ii) adding an aqueous solution of bisulphite ions having a strength of more than 90% of the saturated value, containing not more than 14 mol. per cent of sulphite ions, relative to bisulphite and sulphite combined, optionally with the addition of sulphur dioxide to form bisulphite ions from the sulphite ions, to the mixture in a total amount of from 1.1 to 1.2 mols of bisulphite ion per mol of olefin and the alcohol being present in an amount from 16% to 19% by weight in the final reaction mixture. Reference has been directed by the Comptroller to Specification 1,363,848.
