Sufactant Sodium 3-nitrobenzenesulphonate with CAS 127-68-4
Sodium nitrobenzene sulfonate is a chemical whose molecular formula is C6H4O5NSNa, crystal, melting point 70 °C, soluble in water and ethanol, yellow uniform powder. This product is used as vat dye, anti-dye agent and orange protection agent for dyes, is an intermediate for dyes, and can be used as a ship's rust remover and electroplating nickel-removing agent. Production method: Using benzene as raw material, sulfonation with mixed acid to obtain benzene sulfonic acid, and nitrification with nitric acid to generate m-nitrobenzene sulfonic acid, and then neutralize calcium nitrobenzene sulfonate with lime milk, and replace with soda ash to obtain finished product. Sodium nitrobenzenesulfonate. The product is toxic and its toxicity is slightly less than that of m-nitrobenzene. Since this product is easily deliquescent when exposed to water, when the dust is inhaled, it is easy to hydrolyze with the physiological cycle to reduce the toxicity. Ventilation should be enhanced at the production site. Operators should wear masks, gloves and other protective equipment to prevent inhalation of dust.
