METHOD FOR AGEING THE REACTION MIXTURE IN A SULFONATION PROCESS

A method and a plant for ageing a liquid post-sulfonation reaction mixture comprising linear alkylbenzenesulfonic acid and unreacted linear alkylbenzene using a system of two or more stirred tank reactors which are operated in cycles in filling steps, during which there runs the first step of contin...

Zusammenfassung:	A method and a plant for ageing a liquid post-sulfonation reaction mixture comprising linear alkylbenzenesulfonic acid and unreacted linear alkylbenzene using a system of two or more stirred tank reactors which are operated in cycles in filling steps, during which there runs the first step of continuous ageing at nonsteady-state conditions, followed by ageing steps in batch process conditions.
