Appearance of Vinylsulfonic acid colouless liquid

Vinylsulfonic acid is the organosulfur compound with the formula CH2=CHSO3H. Vinylsulfonic acid is the simplest unsaturated sulfonic acid.[2][3] The C=C double bond is a site of high reactivity. polymerize gives polyvinylsulfonic acid, especially when used as a comonomer with functionalized vinyl[4] and (meth)acrylic acid compounds.[5] Vinylsulfonic acid is a colorless, water-soluble liquid,[2] 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:[6]

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:[7]

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.[8]

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.[9]

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.[10] 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.

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.

APPLICATION of Vinylsulfonic acid

Masse molaire du Acide vinylsulfonique 108,11 g · mol – 1

Aspect liquide sans couleur

L’acide vinylsulfonique est le composé organosulfuré de formule CH2 = CHSO3H. C’est l’acide sulfonique insaturé le plus simple. [2] [3] La double liaison C = C est un site de forte réactivité. polymériser donne de l’acide polyvinylsulfonique, en particulier lorsqu’il est utilisé comme comonomère avec des composés d’acide vinylique [4] et (méth) acrylique fonctionnalisés. [5] L’acide vinylsulfonique est un liquide incolore et soluble dans l’eau [2], bien que les échantillons commerciaux puissent apparaître jaunes ou même rouges.

Préparation de l’Acide vinylsulfonique

L’acide vinylsulfonique est produit industriellement par l’hydrolyse alcaline du sulfate de carbyle avec une acidification subséquente du sel de sulfonate de vinyle résultant: [6]

La réaction est hautement exothermique (enthalpie de réaction: 1 675 kJ / kg) et nécessite un maintien précis de la température et du pH pendant l’hydrolyse. Lorsque l’hydroxyde de calcium est utilisé comme milieu d’hydrolyse, une solution de vinylsulfonate de calcium est obtenue. L’acidification de ce mélange d’hydrolyse avec de l’acide sulfurique donne de l’acide vinylsulfonique, ainsi que du sulfate de calcium peu soluble.

L’acide vinylsulfonique peut également être préparé par déshydratation de l’acide iséthionique avec du pentoxyde de phosphore: [7]

L’acide vinylsulfonique peut également être préparé par sulfochloration du chloroéthane, déshydrohalogénation en chlorure de vinylsulfonyle et hydrolyse ultérieure du chlorure d’acide.

utilisation de L’Acide vinylsulfonique

La double liaison C = C activée de l’acide vinylsulfonique réagit facilement avec les nucléophiles dans une réaction d’addition. L’acide 2-aminoéthanesulfonique est formé avec de l’ammoniac et l’acide 2-méthylaminoéthanesulfonique avec de la méthylamine. [8]

L’acide vinylsulfonique est le monomère dans la préparation d’homopolymères et copolymères hautement acides ou anioniques. Ces polymères sont utilisés dans l’industrie électronique comme résines photosensibles, comme membranes électrolytiques polymères conductrices d’ions (PEM) pour les piles à combustible. Par exemple, des membranes transparentes avec une capacité d’échange ionique élevée et une conductivité protonique peuvent être produites à partir d’acide polyvinylsulfonique. [9]

Recherche

L’acide vinylsulfonique peut également être greffé sur des supports polymères (par exemple le polystyrène) pour donner des échangeurs d’ions hautement acides, qui sont utilisés comme catalyseurs pour l’estérification et les acylations de Friedel-Crafts. [10] Lorsque la fonctionnalité Acide vinylsulfonique n’est pas essentielle, la solution aqueuse alcaline beaucoup plus utilisable de vinylsulfonate de sodium est utilisée, qui est obtenue directement dans l’hydrolyse alcaline du sulfate de carbyle et est commercialisée sous forme de solution aqueuse.

Applications

L’acide vinylsulfonique est un réactif utile (monomère) pour la formation de polymères et copolymères poly (anioniques). L’acide vinylsulfonique est utilisé comme azurant de base et agent de nivellement dans les bains de nickel. L’acide vinylsulfonique est également utilisé comme intermédiaire pour la synthèse organique, le surfactant, l’industrie pharmaceutique.
