Vinylsulfonic acid is the organosulfur compound with the formula CH2=CHSO3H. Vinylsulfonic acid is the simplest unsaturated sulfonic acid. The C=C double bond is a site of high reactivity. polymerize gives polyvinylsulfonic acid, especially when used as a comonomer with functionalized vinyl and (meth)acrylic acid compounds. Vinylsulfonic acid is a colorless, water-soluble liquid, although commercial samples can appear yellow or even red.

Preparation of Vinylsulfonic acid
Vinylsulfonic acid is produced industrially by the alkaline hydrolysis of carbyl sulfate with subsequent acidification of the resulting vinyl sulfonate salt:

The reaction is highly exothermic (reaction enthalpy: 1,675 kJ/kg) and requires exact maintenance of temperature and pH during the hydrolysis. When calcium hydroxide is used as the hydrolysis medium, a solution of calcium vinyl sulfonate is obtained. Acidification of this hydrolysis mixture with sulfuric acid gives vinylsulfonic acid, together with the poorly soluble calcium sulfate.

Vinylsulfonic acid also can be prepared by dehydration of isethionic acid with phosphorus pentoxide:

Vinylsulfonic acid can also be prepared by sulfochlorination of chloroethane, dehydrohalogenation to vinylsulfonyl chloride and subsequent hydrolysis of the acid chloride.

use
The activated C=C double bond of vinylsulfonic acid reacts readily with nucleophiles in an addition reaction. 2-Aminoethanesulfonic acid is formed with ammonia and 2-methylaminoethanesulfonic acid with methylamine.
 
Vinylsulfonic acid is the monomer in the preparation of highly acidic or anionic homopolymers and copolymers. These polymers are used in the electronic industry as photoresists, as ion-conductive polymer electrolyte membranes (PEM) for fuel cells. For example, transparent membranes with high ion exchange capacity and proton conductivity can be produced from polyvinylsulfonic acid.

Research of Vinylsulfonic acid
Vinylsulfonic acid may also be grafted to polymeric supports (e.g. polystyrene) to give highly acidic ion exchangers, which used as catalysts for esterification and Friedel-Crafts acylations. Where the sulfonic acid functionality is not essential, the much more usable alkaline aqueous solution of sodium vinylsulfonate is used, which is obtained directly in the alkaline hydrolysis of the carbyl sulfate and is commercially supplied as an aqueous solution.

Applications of Vinylsulfonic acid
Vinylsulfonic acid is a useful reagent (monomer) for the formation of poly(anionic) polymers and copolymers. Vinylsulfonic acid is employed as a basic brightener and leveling agent in nickel baths. Vinylsulfonic acid is also used as intermediate for organic synthesis, surfactant, pharmaceutical industry.

The subject invention provides:
a method for producing vinyl sulfonic acid, comprising conducting demetallation of vinyl sulfonate salt, wherein the demetallation rate is not less than 95% according to the following formula:
Demetallation rate(%)={(acid value after demetallation)/(acid value before demetallation)}×100;

vinylsulfonic acid) (PVS) possesses a high acid content (ion‐exchange capacity in the chemical formula = 9.2 meq · g-1). Its monomer, vinylsulfonic acid (VSA), had a high acid dissociation ability (Hammett acid function = 0.74 in water), and a high ionic conductivity (0.04-0.11 S · cm-1). The radical polymerization of Vinylsulfonic acid with various initiators was kinetically investigated. The ESR spectrum of the Vinylsulfonic acid polymerization mixture showed a strong signal ascribed to the propagation carbon radical of Vinylsulfonic acid. The molecular weight of PVS increased with the increasing monomer concentration and decreasing radical initiator concentration to yield the PVS with a molecular weight of 4.0 × 104. Proton‐conductivity of PVS under hydrated and nonhumidified conditions was on the order of 10-1 and 10-3-10-6 S · cm-1, respectively.

DESCRIPTION of Vinylsulfonic acid

Low Color Stabilizer Vinylsulfonic acid Contains Sulphonate Group that Polymerize, Also Modify Olefinic Bond And Boost End Solubility Of The End Product. Water-Based Adhesive, Water-Based Paint Resin And Nickel Shine Producer.Vinylsulfonic acid is a polymerizable organic compound which has many industrial uses, particularly as an antistatic agent and as an agent improving the tinctorial affinity of synthetic fibres, such as polyacrylonitrile and polypropylene, to cationic dyes, as a dispersing agent in polymer emulsions, as a wetting agent for lowering the mixing water content of cement, as a starting material for the production of cation exchange resins and synthetic rubber.Vinylsulfonic acid and its derivatives can be prepared from ß-chloroethanesulfonyl chloride or carbyl sulfate (ß-hydroxysulfonyloxyethanesulfonic anhydride). The chemistry of vinylsulfonic acid has assumed industrial importance since the discovery of a simple synthesis of ß-chloroethanesulfonyl chloride from chloroethane or ethane, sulfur dioxide, and chlorine by the Reed process. Carbyl sulfate is as important a starting material as ß-chloroethanesulfonyl chloride, and surpasses the latter in some respects, e.g. on account of the low price of its components ethylene and sulfur trioxide. Vinylsulfonates undergo addition reactions with alcohols, phenols, thiols, sulfinic acids, carboxylic acids, amides, imides, and hydrazides, as well as with amines, ureas, diazonium salts, and nitroparaffins. Furthermore, they undergo halogenation, nitration, olefination, and the Diels-Adler reaction. - Methods for the preparation of the free vinylsulfonic acid are described. Alkyl vinylsulfonates are excellent alkylating agents. The derivatives of vinylsulfonic acid are used e.g. as plasticizers, emulsifiers, and fungicides.More easily handled than the acid is the salt, sodium vinylsulfonate, which is commercially supplied as an aqueous solution.

The activated C=C double bond of vinylsulfonic acid reacts readily with nucleophiles in an addition reaction. 2-Aminoethanesulfonic acid is formed with ammonia and 2-methylaminoethanesulfonic acid with methylamine.

Vinylsulfonic acid is the monomer in the preparation of highly acidic or anionic homopolymers and copolymers. These polymers are used in the electronic industry as photoresists, as ion-conductive polymer electrolyte membranes (PEM) for fuel cells. For example, transparent membranes with high ion exchange capacity and proton conductivity can be produced from polyvinylsulfonic acid.

Research of Vinylsulfonic acid
Vinylsulfonic acid may also be grafted to polymeric supports (e.g. polystyrene) to give highly acidic ion exchangers, which used as catalysts for esterification and Friedel-Crafts acylations. Where the sulfonic acid functionality is not essential, the much more usable alkaline aqueous solution of sodium vinylsulfonate is used, which is obtained directly in the alkaline hydrolysis of the carbyl sulfate and is commercially supplied as an aqueous solution.

Applications of Vinylsulfonic acid
Vinylsulfonic acid is a useful reagent (monomer) for the formation of poly(anionic) polymers and copolymers. Vinylsulfonic acid is employed as a basic brightener and leveling agent in nickel baths. Vinylsulfonic acid is also used as intermediate for organic synthesis, surfactant, pharmaceutical industry.

The subject invention provides:
a method for producing vinyl sulfonic acid, comprising conducting demetallation of vinyl sulfonate salt, wherein the demetallation rate is not less than 95% according to the following formula:
Demetallation rate(%)={(acid value after demetallation)/(acid value before demetallation)}×100;
a method for producing vinyl sulfonic acid, comprising conducting demetallation of vinyl sulfonate salt, wherein demetallation is carried out using a strongly acidic ion exchange resin; and
said method further comprising the step of purifying a product of the demetallation using a thin film evaporator.
vinylsulfonic acid) (PVS) possesses a high acid content (ion‐exchange capacity in the chemical formula = 9.2 meq · g-1). Its monomer, vinylsulfonic acid (VSA), had a high acid dissociation ability (Hammett acid function = 0.74 in water), and a high ionic conductivity (0.04-0.11 S · cm-1). The radical polymerization of Vinylsulfonic acid with various initiators was kinetically investigated. The ESR spectrum of the Vinylsulfonic acid polymerization mixture showed a strong signal ascribed to the propagation carbon radical of Vinylsulfonic acid.
