Process for producing vinylsulfonic acid |
| abstract |
A process for producing vinylsulfonic acid which comprises the step of demetallizing a vinylsulfonic acid salt, wherein the degree of demetallization represented by the equation: degree of demetallization (%) = {(acid value after demetallization)/(acid value before demetallization)} × 100 is 95% or higher. Also provided is a process for producing vinylsulfonic acid which comprises the step of demetallizing a vinylsulfonic acid salt, wherein the demetallization is a treatment with a strongly acidic ion-exchange resin. The processes for vinylsulfonic acid production may further include the step of purification with a thin-film distillation apparatus. |
