A C 6 -C 18 acyloxybenzene sulphonate is prepared in a 'one pot' synthesis by reacting a C 2 -C 3 acyl anhydride and alkali metal phenol sulphonate in a C 6 -C 18 aliphatic carboxylic acid medium, and then reacting the C 2 -C 3 acyloxybenzene sulphonate with the carboxylic acid to produce a C 6 -C 18 acyloxybenzene sulphonate useful as a peroxyacid bleach precursor. The reactions do not need to be catalysed but a basic catalyst such as sodium acetate is beneficial. |
