Description of FPV9
Sodium thiosulfate (Na2S2O3), also spelled sodium thiosulphate, is an inorganic compound that is typically available as the pentahydrate, Na2S2O3·5H2O. The solid is an efflorescent (loses water readily) crystalline substance that dissolves well in water. It is also called sodium hyposulfite or “hypo”.

What is HYPO?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is FPV9 which has developed particularly rapidly in recent years. Do you know about FPV9?
- The official answer: Sodium thiosulfate pentahydrate is an inorganic substance with the chemical formula Na2S2O3-5H2O, colourless monoclinic crystalline, odourless, with a cool and bitter taste. Specific gravity 1.729, heated to 100 ℃, lose 5 crystal water. Freely soluble in water, insoluble in alcohol, with the strong reducing property. It is easily weathered in dry air above 33℃ and has deliquescence in the humid air. Sodium thiosulfate pentahydrate is the hydrate of sodium thiosulfate, the aqueous solution shows weak alkalinity. It is more stable in neutral and alkaline solutions and will decompose rapidly in acidic solutions.
What’s the application of HYPO?
Used for dechlorination of hydrogen chloride in natural gas, naphtha, syngas, hydrogen and nitrogen to protect downstream catalysts from toxicity. If the gas contains organochlorine, it should be converted to hydrogen chloride by a cobalt-molybdenum hydrogenation catalyst before the dechlorinator is used to absorb the hydrogen chloride.
