Product Details

Products Description of Sodium Hydroxymethanesulphinate CAS#149-44-0

Sodium bisulfite formaldehyde is translucent white orthorhombic crystals or small pieces. Apparent density 1.80～1.85g/cm3. Easily soluble in water, slightly soluble in alcohol. It has extremely strong reducing properties under high temperature and can make the dyed color disappear, so it is known as the chemical book of hanging white blocks. It decomposes when exposed to acid, and decomposes at 120°C to produce toxic gases such as formaldehyde and hydrogen sulfide. Anhydrous suspension white blocks are stable but will gradually decompose in humid air. Aqueous solutions begin to decompose above 60°C, and dilute solutions decompose much faster than concentrated solutions.

Product Application of Sodium Hydroxymethanesulphinate CAS#149-44-0

It is mainly used in the printing and dyeing industry as a dye discharge agent, discharging agent, reducing agent and as an activator for styrene-butadiene rubber and synthetic resin. It is also used in the decolorization and bleaching of some organic substances (such as synthetic rubber, sugar and food industries). agent), which can be used instead of insurance powder under certain conditions.
