| titleOfInvention | Purification of sulphonic acid esters |
| abstract | Coloured contaminants are removed from a crude ester having the formula R1SO2OR2, where R1 is a saturated open chain hydrocarbon radical containing 9-18 carbon atoms and R2 is an aromatic or aliphatic radical, by contacting the crude ester with (a) aqueous alkali metal hydroxide and (b) isopropanol, components (a) and (b) being added either together or separately in either order, and thereafter separating from the mixture an upper liquid layer containing the ester. Any hydrocarbon R1H present in the separated upper liquid layer may be removed by steam stripping preferably at reduced pressure. |
