Preparation of esters |
| abstract |
A process for preparing a phenol ester of formula In n(wherein R 1 is a linear or branched alkyl or alkenyl groupnoptionally interrupted by an -O- or -NH- group and optionallynsubstituted by an oxo group and L is a group of formulan nin which R2 is an alkyl group or alkylene chain and Y is a groupn-CO2 - M + , SO3 - M + ornPO4 - M + (wherein M is a cation)) comprising the step ofnreacting a substituted phenol corresponding to L with either (1) ancarboxylic acid corresponding to R 1 CO- in the presence of anchlorinating agent or (2) an acyl chloride corresponding tonR 1 CO- in the presence of a tertiary amine or tertiary amidencatalyst. |
