Applications and precautions related to Sodium Formaldehyde Sulfoxylate
2. Applications and precautions SFL is the one of the most effective and convenient industrial bleaching agent, but apart from a bleaching agent, it has several other applications that can be attributed to its bleaching, reducing and dihydrate properties also. For emulsion polymerization, SFL emerges as an effective reducing agent in redox-initiator systems SLS is used as a reducing agent as well as a bleaching agent when it comes to indigo based VAT dying T-butyl peroxide, a pair example of redox, it an efficient in reducing chlorine, and therefore is suitable to use in large aquariums or an aquaria As a bleaching or discharge agent, SFL is used as an agent hair dyes, rubber, plastic and textiles, paints and soaps
Use
The original use of Rongalite C was as industrial bleaching agent and as a reducing agent for vat dyeing.Another large-scale use is as a reducing agent in redox-initiator systems for emulsion polymerization. One of the typical redox pair examples is t-butyl peroxide. A niche use is its use as water conditioner for aquaria as it rapidly reduces chlorine and chloramine and reacts with ammonia to form the innocuous aminomethylsulfinate ion. It is also used as an antioxidant in pharmaceutical formulation.
The compound has been used increasingly in commercial cosmetic hair dye colour removers despite the generation of formaldehyde, a known human carcinogen.
Rongalite C has a variety of specialized applications in organic synthesis.

Synthesis and reactions
Although available commercially, the salt can be prepared from sodium dithionite and formaldehyde:
Na2S2O4 + 2 CH2O + H2O → HO-CH2-SO3Na + HO-CH2-SO2Na
This reaction proceeds quantitatively, such that dithionite can be determined by its conversion to Rongalite, which is far less O2-sensitive and thus easier to handle.
Formaldehyde Sodium sulfoxylate ion is unstable in solution towards decomposition to formaldehyde and sulfite. Addition of at least one equivalent of formaldehyde pushes the equilibrium towards the side of the adduct and reacts further to give the bis-(hydroxymethyl)sulfone. Such solutions are shelf-stable indefinitely.
Formaldehyde Sodium sulfoxylate was originally developed in the early 20th century for the textile industry as a shelf-stable source of sulfoxylate ion, where the latter can be generated at will. In use, when Formaldehyde Sodium sulfoxylate is made acidic, the reducing sulfoxylate ion and formaldehyde are released in equimolar amounts. For safety reasons the generation of formaldehyde must be taken into consideration when used industrially.
NaHOCH2SO2 can essentially be considered to be a source of SO22-. As such Formaldehyde Sodium sulfoxylate is used both as a reducing agent and as a reagent to introduce SO2 groups into organic molecules. Treatment of elemental Se and Te with NaHOCH2SO2 gives solutions containing the corresponding Na2Sex and Na2Tex, where x is approximately 2. As a nucleophile, NaHOCH2SO2 reacts with alkylating agents to give sulfones.
HO-CH2-SO2Na + 2 C6H5CH2Br → [C6H5CH2]2SO2 + NaBr + CH2O + HBr
Occasionally, alkylation will occur also at oxygen, thus α,α’-dibromoxylene gives both the sulfone and the isomeric sulfinate ester.

Since 1926 our portfolio has included industrial chemicals. The company has had experience with producing and marketing sulfur-based, and later also formaldehyde-free reducing agents. Discovered over 100 years ago, Formaldehyde Sodium sulfoxylate(SFS) is still one of the most important industrial reducing agents used today. We keep developing our reducing agents in light of new market requirements and application possibilities. In addition to the textile industry, they are also used as initiators in the production of polymer dispersions, in an increasingly important and very demanding and diverse field.
Formaldehyde-Free Reducing Agents
Stricter environmental regulations, higher demands on products, and increasing cost pressure:
Confronted with these challenges, manufacturers of polymer dispersions are increasingly dependent on reducing agents that exceed their conventional performance capacity.
Polymerization of acrylonitrile in aqueous system using watersoluble redox catalyst system comprising oxidizing catalyst and reducing bisulfite activator is improved by (a) conducting the polymerization in the presence of 0.1 to 0.5 parts of Formaldehyde Sodium sulfoxylate 100 parts of monomer to inhibit cyanide by-product formation and/or (b) the use of sodium sulfoxylate formaldehyde to shortstop the polymerization reaction while minimizing the formation of undesirable water-soluble acrylonitrile-bisulfite addition product.

Synthèse et réactions
Bien que disponible dans le commerce, le sel peut être préparé à partir de dithionite de sodium et de formaldéhyde :
Na 2 S 2 O 4 + 2 CH 2 O + H 2 O → HO-CH 2 -SO 3 Na + HO-CH 2 -SO 2 Na
Cette réaction se déroule quantitativement, de sorte que le dithionite peut être déterminé par sa conversion en Rongalite, qui est beaucoup moins sensible à l’ O 2 et donc plus facile à manipuler.
L’ion du Formaldehyde Sodium sulfoxylate (Rongalite c)est instable en solution vers la décomposition en formaldéhyde et sulfite. L’addition d’au moins un équivalent de formaldéhyde pousse l’équilibre vers le côté du produit d’addition et réagit davantage pour donner la bis – (hydroxyméthyl) sulfone. Ces solutions sont indéfiniment stables à la conservation.
La Formaldehyde Sodium sulfoxylate (Rongalite c) a été initialement développé au début du XXe siècle pour l’industrie textile en tant que source stable d’ions sulfoxylate, où ces derniers peuvent être générés à volonté. En utilisation, lorsque La Formaldehyde Sodium sulfoxylate (Rongalite c) est rendu acide, l’ion sulfoxylate réducteur et le formaldéhyde sont libérés en quantités équimolaires. Pour des raisons de sécurité, la génération de La Formaldehyde Sodium sulfoxylate (Rongalite c) doit être prise en compte lors d’une utilisation industrielle.
Le NaHOCH 2 SO 2 peut essentiellement être considéré comme une source de SO 2 2- . En tant que tel, La Formaldehyde Sodium sulfoxylate (Rongalite c) est utilisé à la fois comme agent réducteur et comme réactif pour introduire des groupes SO 2 dans des molécules organiques. Le traitement de Se et Te élémentaire avec NaHOCH 2 SO 2 donne des solutions contenant le Na 2 Se x et Na 2 Te x correspondant , où x est d’environ 2. En tant que nucléophile, NaHOCH 2 SO 2 réagit avec les agents alkylants pour donner des sulfones .
HO-CH 2 -SO 2 Na + 2 C 6 H 5 CH 2 Br → [C 6 H 5 CH 2 ] 2 SO 2 + NaBr + CH 2 O + HBr
Parfois, l’alkylation se produira également à l’oxygène, ainsi l’α, α’-dibromoxylène donne à la fois la sulfone et l’ ester de sulfinate isomère .
Utilisez
À l’origine, le composé était utilisé comme agent de blanchiment industriel et comme agent réducteur pour la teinture en cuve . [1] Une autre utilisation à grande échelle est comme agent réducteur dans les systèmes initiateurs redox pour la polymérisation en émulsion. Le peroxyde de t-butyle est l’un des exemples typiques de paires redox. Une utilisation de niche est son utilisation comme conditionneur d’eau pour les aquariums car elle réduit rapidement le chlore et la chloramine et réagit avec l’ ammoniac pour former l’ion aminométhylsulfinate inoffensif. [2] Il est également utilisé comme antioxydant dans la formulation pharmaceutique.
Le composé est de plus en plus utilisé dans les décolorants cosmétiques pour la coloration des cheveux dans le commerce malgré la génération de formaldéhyde , un cancérogène connu pour l’ homme .
La Formaldehyde Sodium sulfoxylate (Rongalite c) a une variété d’applications spécialisées en synthèse organique . [3] [4]
