DESCRIPTION:
Rongalite and its derivatives are widely used in the dye industry.
The structure of this salt has been confirmed by X-ray crystallography.
Rongalite is a chemical compound with the molecular formula Na + HOCH2SO2−.
The original use of the Rongalite was as an industrial bleaching agent and as a reducing agent for boat dyeing.
Another large-scale use of Rongalite is as a reducing agent in redox initiator systems for emulsion polymerization.
Rongalite is a niche use as a water conditioner for aquariums as it rapidly reduces chlorine and chloramine and reacts with ammonia to form the harmless aminomethylsulfinate ion.
Rongalite is also used as an antioxidant in pharmaceutical formulation.
Generally Rongalite is water soluble and dihydrate.
Rongalite can be used as reducing agent thanks to the elements it contains.
Rongalite is water-soluble and generally sold as the dihydrate.
Rongalite is a sodium bisulphite formaldehyde, is a kind of important chemical feedstocks.
Rongalite is widely used in rubber industry and does the agent of styrene-butadiene rubber(SBR) polymerization activity, the industry of printing and dyeing stamp discharging agent, sensitive photographic material auxiliary agent and dairy industry.
Rongalite acts as a bleaching agent and it is used in printing and dying industry.
Due to its ability to deliver SO2 dianion, Rongalite is useful to prepare sultines and sulfones.
Rongalite is the sodium salt of 2-hydroxyethane sulfonic acid (isethionic acid).
Rongalite is used as a hydrophilic head group in washing-active surfactants, known as isethionates due to its strong polarity and resistance to multivalent ions.
Rongalite is a colorless, free-flowing, non-hygroscopic solid, which dissolves readily in water and has good biodegradability.
Due to the method of synthesis samples often contain traces of sodium sulfite or sodium hydrogen sulfite causing aqueous solution to possesses a mildly alkaline pH of about 10.
The main use of Rongalite is the production of the isethionate class of surfactants.
These are readily foaming and particularly mild, making them suitable for cleaning sensitive skin and are therefore mainly used in baby soaps and shampoos.
Because of its pronounced skin compatibility Rongalite is added to soaps and liquid skin cleansers with up to 15 parts by weight.
From Rongalite the so-called biological buffers such as HEPES, MES, PIPES etc. are easily accessible.
The addition of Rongalite to electroplating baths allows higher current densities and lower concentrations than the much more expensive methane sulphonic acid with improved appearance.
USES:
The original use of Rongalite 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.
Rongalite is also used as an antioxidant in pharmaceutical formulation.
Rongalite has been used increasingly in commercial cosmetic hair dye colour removers despite the generation of formaldehyde, a known human carcinogen.
Rongalite has a variety of specialized applications in organic synthesis.
APPLICATION:
-Textile:
In the weaving and knitting sector, Rongalite is mainly used as cellulosic printing and industrial bleach.
-Paint:
Rongalite is used as an auxiliary component in boat painting materials.
-Chemistry:
In the chemical industry, the redox initiator is also used as an oxidant in pharmaceutical reactions.
-Water:
With the mixture formed by reacting with ammonia in appropriate conditions, water treatment is used especially in aquarium cleaning.
-Cosmetic:
The interaction wth formaldehyde is preferably used in hair dye removal processes.
