Synthesis of hydrophilic phenol ester derivatives |
| abstract |
SYNTHESIS OF HYDROPHILIC PHENOL ESTER DERIVATIVES ABSTRACT A hydrophilic phenol ester derivative, especially a sulphonated or carboxylated phenol ester is prepared by reacting a C6-C18 substituted or unsubstituted aliphatic carboxylic acid with a C2-C3 alkanoic anhydride, and reacting the resultant C6-C18 acid anhydride with a substituted phenol such as an alkali metal phenol sulphonate salt or hydroxybenzene carboxylic acid to give a C6-C18 acyloxy derivative of a substituted benzene. The two stage process may be carried out in the same reaction vessel without the use of solvents. The products are useful as peroxyacid bleach precursors. |
