A Useful Reagent for Industry and Life

Rongaliteis sodium formaldehyde sulfoxylate, which is represented by the chemical formula Na+HOCH2SO2–.2H2O. The salt has many names, such as rongalit, sodium bisulfoxylate formaldehyde, formalhyde sodium bisulfite adduct, formaldehyde sodium sulfoxylate, sodium methanalsulfoxyalte, sodium oxymethanesufinic acid.

It is a strongly hygroscopic substance and should be stored in a dry, cool, dark place, protected from moisture.

Rongaliteis odorless or with a slightly leek odor.

The existing methods for the preparation ofrongaliteare the three-step and one-step methods and it is commercially available as lump and powder to meet the demands of various industrial applications.

Rongaliteis commonly used as a capturing-color agent in printing and dyeing industry, activation in rubber synthetics and industry bleacher.

It is an excellent decolouring agent for some organic compounds and also for sugar etc.

Due to its reducing property,rongaliteforms an important part of the various redox initiator systems for polymerisation reactions.Rongalitehas been used as an antidote against heavy metal (e.g., Hg,Au, Cu, Ba, Sb, Pb, and Bi) poisoning and also as a photographic developer or an additive to photographic developers.
