CONTINUOUS PRODUCTION OF ACYLOXYBENZENESULFONIC ACID
A process for the continuous production of C7-Cl2-acyloxybenzenesulfonic acids, wherein phenol and a sulfonating reagent, diluted with an aliphatic C7-Cl2-carboxylic acid, is charged to the top of a continuous-flow reactor heated to 80 DEG -100 DEG and the mixture of phenolsulfonic acid and the alip...

| Zusammenfassung: | A process for the continuous production of C7-Cl2-acyloxybenzenesulfonic acids, wherein phenol and a sulfonating reagent, diluted with an aliphatic C7-Cl2-carboxylic acid, is charged to the top of a continuous-flow reactor heated to 80 DEG -100 DEG and the mixture of phenolsulfonic acid and the aliphatic carboxylic acid, leaving the bottom end of this continuous-flow reactor, and a chlorinating reagent are charged to the top of a second continuous-flow reactor, nitrogen being passed in counter-current through both continuous-flow reactors. |
