Continuous method for producing alkali metal styrenesulfonate |
| abstract |
(57) [Problem] To provide a continuous method for producing alkali metal styrenesulfonate having high purity, good productivity and good operability. SOLUTION: An aqueous solution of β-haloethylbenzenesulfonic acid and / or an alkali metal hydroxide solution of β-haloethylbenzenesulfonic acid and / or an aqueous solution of an alkali metal hydroxide are continuously introduced into a crystallization tank. The styrene sulfonic acid alkali metal salt concentration is set to 1 to 20% by weight of the total amount, the styrene sulfonic acid alkali metal salt is reacted and crystallized, and a slurry of the styrene sulfonic acid alkali metal salt is continuously withdrawn. Is used. |
