Sodium formaldehyde sulphoxylate is the sodium salt of formaldehyde sulphoxylic acid. When pure it crystallizes with two molecules of water, having the following formula: OHCH2.SO2.Na.2H20.

It is a very strong reducing agent. The product as ordinarily obtained is unstable in the presence of acids and strong alkalies and slowly decomposes in the presence of atmospheric oxygen forming thiosulphates, sulphites and free sulphur which react with the formaldehyde to form products having a strong garlic-like odor. Decomposition can be detected readily by this strong peculiar garlic-like odor.

The preparation of sodium formaldehyde sulphoxylate by reduction of formaldehyde bisulphite with zinc dust and acetic acid is described in Ber. 38, 1076; 1905. The technical product, as used Sin commerce, occurs in white irregular lumps and is said to be stabilized by addition of excess formaldehyde and excess alkali (sodium hydroxide).

The technical product is thus considered to be more stable than the pure crystalline product.

1. Direct printing with vat dyestuffs

Application

For direct printing with vat dyestuffs, a stock thickening is used contain- ing 130 – 140 g/kg Rongalit Discharge C and also the same amount of 1,1 potash.

Potash can be wholly or partly substituted by soda ash. 100 parts of potash can be replaced by 75 of soda ash.
Example of the stock thickening: 550 g Thickener
30-50g  Glycerine
130 g Potash or 100 g Soda ash 130 g Rongalit Discharge C
… g Water or thickening 1000 g
Due to its good solubility, Rongalit Discharge C can be added directly to the thickening with stirring

The thickener should be set with a neutral or alkaline pH.
The above quantities relate to rotary screen printing. In flat screen print- ing the reducing agent and the alkali can be reduced by 20%.

The actual print colour has the following composition:
… g Vat dyestuff (Printing grades!) 650 g Stock thickening
… g Water or thickening 1000 g

After printing and drying the fabric is steamed for 8 – 12 minutes with saturated steam (102 ºC, „air free “).

2.    Coloured discharges with vat dyes on dischargeable dyed cellulose fibres
For coloured discharge printing with vat dyes on dischargeable dyeings on cellulosic fibres the above stock thickening is also very well suited. Depending on the dischargeability and colour depth of the dyed ground, it may be necessary to increase the proportion of Rongalit  Discharge C and possibly also to increase the amount of potash and / or soda ash.
3.    White discharge prints on dischargeable dyeings on cellulose fibres
For white discharge prints, Rongalit Discharge C has proved successful as discharge agent and reducing agent.
Example for the composition of white discharge pastes:

Paste „A“    Paste „B“
Thickener:    500 g    500 g
Rongalit Discharge C:    150 g    200 g
Suitable discharge resistant optical brightener:    10 g    10 g
Mix together, then
Caustic soda 38 °Bé    –    40 g
Soda ash    –    40 g
Water or thickening to    340 g        210 g 1000 g
White discharge paste „A“ is intended for discharge prints on easily dis- chargeable dyeings with substantive and reactive dyes.

Print paste „B“ is for white discharge prints on dyeings with more difficult to discharge reactive dyes and naphthol combinations. Also in this case the caustic soda may be wholly or partly replaced by soda ash.

After drying steaming is carried out for 8–10 minutes with saturated steam (102 ºC, „air free“).
4.    Two phase printing process with vat dyes
Two phase printing process is another application area for Rongalit Discharge C. In comparison to Rongalit Reducer 2PHA (previously Rongalit 2PHA) + Rongalit Reducer 2PHB Liq. (previously Rongalit 2PHB Liquid), which were specially developed for the two phase process with vat dyes, Rongalit Discharge C is a slower reaction. It takes a longer steaming time and the product is therefore particularly suitable for textile printers who do not have the opportunity to fix the vat dyes in a special two-phase shock (Flash ager) within a few seconds,
Application rate. 100 g Rongalit Discharge C

The printed and dried fabrics are padded in a padding mangle and steamed for 5–7 minutes with saturated steam or slightly superheated steam (110–115 °C). Finally the fabric is rinsed, alkaline re-oxidised and given a boiling soaping treatment. An addition of acid is made to the soaping bath or one of the following soaping baths.

Conversion table    The following table can be used to convert the amount of caustic soda in
the corresponding volume or by unit of weight of sodium hydroxide solu- tion.
100 g caustic soda (fixed) correspond to:

347 g or 263 ml NaOH 35 °Bé =  64,0 °TW
307 g or 227 ml NaOH 38 °Bé =  71,4 °TW
286 g or 206 ml NaOH 40 °Bé =  76,6 °TW
238 g or 164 ml NaOH 45 °Bé =  90,6 °TW
214 g or 143 ml NaOH 48 °Bé =  99,6 °TW
206 g or 136 ml NaOH 49 °Bé = 102,8 °TW
200 g or 130 ml NaOH 50 °Bé = 106,0 °TW
Note    Thorough after-washing of the print is essential Safety

Rongalite is a chemical compound with the molecular formula Na+HOCH2SO2−.
This salt has many additional names, including Rongalit, sodium hydroxymethylsulfinate, sodium formaldehyde sulfoxylate, and Bruggolite.
Rongalite is listed in the European Cosmetics Directive as sodium oxymethylene sulfoxylate (INCI).
Rongalite is water-soluble and generally sold as the dihydrate. Rongalite and its derivatives are widely used in the dye industry.

IUPAC name: Sodium hydroxymethanesulfinate
Other names: Sodium formaldehydesulfoxylate, sodium oxymethylene sulfoxylate, Brüggolit

CAS Number
149-44-0
6035-47-8 (dihydrate)

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.

The hydroxymethanesulfinate 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.

Sodium hydroxymethanesulfinate 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 sodium hydroxymethanesulfinate 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 it 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.

Use
The original use of the compound 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.

Application
Rongalit C is mainly used as a discharging agent, color-discharging agent, reductant in printing and dyeing industry, as an activating agent for production styrene-butadise rubber and synthetic resin
Rongalit C can also be used to decolourize and bleach some organic matters. It is used as a bleaching agent in synthetic rubber, sugar-making, and food industries.

The compound has been used increasingly in commercial cosmetic hair dye colour removers despite the generation of formaldehyde, a known human carcinogen.

It has a variety of specialized applications in organic synthesis.

Sodium formaldehydesulfoxylate (SFS) is a long name for a rather small molecule. It also goes by the name sodium hydroxymethanesulfinate or, most commonly, its trade name Rongalite. It is usually marketed as the dihydrate.

SFS has a long history:

In a short 1908 US patent assigned to Heyden Chemical Works (New York), Bruno R. Seifert and Otto W. Meves reduced formaldehyde and sulfur dioxide with zinc dust to a paste containing a zinc formaldehydesulfoxylate that could be converted to the sodium salt with sodium hydroxide or carbonate.
In a 1922 article, Frederick W. Heyl and Frank E. Greer of Upjohn1 (Kalamazoo, MI) reported an improved synthesis of a method described in a 1913 German patent. A mixture of formaldehyde and sodium hydrogen sulfite is treated with a mixture of zinc dust and zinc oxide. A convoluted purification process leads to acceptably pure SFS.
A 1935 patent by Frederick W. Binns at the Virginia Smelting Co.2 (Portland, ME) describes a similar synthesis that starts from zinc, sulfur dioxide, and formaldehyde.
Today SFS is manufactured from sodium dithionite (Na2S2O4) and formaldehyde.
It was originally developed as a treatment for mercury poisoning (hence its pharmaceutical origin), but that was of limited value.
Its current uses are in vat dyeing as a reducing agent, in redox polymerization initiator systems, and for aquarium water conditioning.

Hydroxymethanesulfinic acid is an organic acid. Sodium salt of hydroxymethanesulfinic acid (rongalite) is widely used in organic synthesis.
Sodium formaldehydesulfoxylate can be used as a reducing agent for elemental selenium and tellurium, diselenides, α‐halo ketones, and aromatic aldehydes; yields symmetrical sulfones with primary halides and with Michael acceptors.

Production method of sodium formaldehyde sulfoxylate
Abstract
The invention discloses a production method of sodium formaldehyde sulfoxylate.
In the production method, anhydrous sodium sulfite is firstly added in the concentration process of a prepared sodium formaldehyde sulfoxylate solution; and a sodium hydroxide solution or a soda ash solution is added before the prepared sodium formaldehyde sulfoxylate solution is concentrated.
The advantage is to provide a production method of odorless anhydrous sodium sulfite, thus the odor of free formaldehyde in products is eliminated, the odor generated because products are affected with damp and decomposed is eliminated, and moisture absorption, caking and decomposition of products are prevented, so that the storage stationary phase of the products is long and can be stored for a year under a closed state but not caked and stunk, and the product quality is improved; 35% of aqueous solution is transparent after the product is dissolved; and the production method is environment-friendly and clean, and is suitable for production of platy, blocky, powdered, granular and crushed sodium formaldehyde sulfoxylate products.
