Rongalite is also called sodium bisulfate formaldehyde. Translucent white rhombic crystals or small pieces. The apparent density of 1.80 ~ 1.85 g/cm3. Melting point 64 ℃ (dissolve in the water of crystallization). Higher than 120 ℃. Soluble in water, slightly soluble in alcohol. Anhydrous salt is more stable. But in the moist air will gradually decompose. Has the strong reducibility under high temperature. Match ChengLiao pulp by zinc powder and water, ventilation with sulfur dioxide reaction, generate two zinc sulfate, add formaldehyde addition, zinc powder reduction react with sodium hydroxide to produce again. Used for dyeing and printing of discharging agent and reducing agent and can be used for synthetic rubber, sugar, the production of indigo dye and VAT dye.
|Product name||Sodium formaldehyde bisulfite|
Formaldehyde Sodium Bisulfite is used in the preparation of oil-soluble sulfonate additives used in improving anticorrosive, dispersant and antioxygenic properties of lubricant oils. Also used in chemical reactions in the preparation of chiral salen Mn(III) catalysts or lignosulfonates as dispersant for gypsum paste.
