Uses and synthesis of Formaldehyde sodium bisulfite powder

Formaldehyde sodium bisulfite powder is a kind of high polymer, which should be used in combination with SP, M, N, P, AESS, GISS, etc. Formaldehyde sodium bisulfite CAS 870-72-4 has strong cathode polarization, can significantly enhance the brightness of the low area, and is widely used in formaldehyde sodium bisulfite, Formaldehyde sodium bisulfite Raw Materials can effectively complex copper, zinc, lead and other metal ions.

Applications/Functions of Formaldehyde sodium bisulfite powder

• Formaldehyde sodium bisulfite powder is used to produce formaldehyde sodium bisulfite, neoarsphenamine, and sodium isoniazid sulfonate.
• Formaldehyde sodium bisulfite CAS 870-72-4 is used as an electroplating additive intermediate to prepare nickel plating brightener
• Nickel plating brightener can improve brightening and leveling effect

Physicochemical Property of Formaldehyde sodium bisulfite powder

Formaldehyde sodium bisulfite Raw Materials The monohydrate precipitated from water is a needle-like crystal.

Production methodprocess of Formaldehyde sodium bisulfite powder

1. Add distilled water and formaldehyde solution into the reaction pot, cool to below 15℃, stir and add sodium bisulfite in batches, control the temperature at 60-65℃ for 20min, and use sodium hydroxide solution to control pH9. After the reaction is complete, add hydrochloric acid so that the pH reaches about 3.
2. Decolorization with activated carbon, filtration, cooling of filtrate, precipitation of ethanol into solid, place, filtration the next day, ethanol washing, drying, and Formaldehyde sodium bisulfite powder.
