| titleOfInvention | A process for the manufacture of hydroxyalkanesulphonic acids or salts thereof |
| abstract | Hydroxyalkanesulphonic acids or salts thereof are obtained by reacting an olefinic aliphatic alcohol having more than three carbon atoms per molecule with a neutral or weakly alkaline aqueous solution of a water-soluble salt of sulphurous acid in the presence of finely distributed oxygen or an oxygen containing gas. As starting materials there may be used crotonyl alcohol, pentene-3,4-ol-2 allyl carbinol, dimethylallyl carbinol, diethylallyl carbinol, methylpropylallyl carbinol, pentene-4,5-ol-2, and pentene-4,5-ol-1. Oxygen may be supplied as air, oxygen gas or agents which evolve oxygen, e.g. hydrogen peroxide. An excess of sulphite, e.g. 20-60 per cent above the theoretical quantity required, is desirable. Examples describe the preparation of 3-hydroxy-butane-1-sulphonic acid and of 4-hydroxy-butane-1-sulphonic acid. |
