Top Quality Sodium Naphthalene Sulphonate Formaldehyde

Top Quality Sodium Naphthalene Sulphonate Formaldehyde

The sodium salt of polynaphthaldehyde sulfonate is a brown or dark brown powder. Often used. This product is easily soluble in water, resistant to acid, alkali, salt and hard water, and has good diffusion properties. It is mainly used as dispersant in disperse dyes, vat dyes, reactive dyes, acid dyes and leather dyes. It has excellent grinding effect, solubilization and dispersibility. It can also be used as dispersant for textile printing and dyeing, wettable pesticides, and dispersant for papermaking. Electroplating additives, latex, rubber, construction cement concrete water reducer, used as oil well cement water reducer, water-soluble paint, pigment dispersant, oil drilling, water treatment agent, carbon black dispersant, etc.

The preparation process of this product includes three steps: naphthalene sulfonation, condensation of sulfonated product and formaldehyde, and neutralization. Put 550kg of refined naphthalene into the reaction kettle, raise the temperature to 50°C, and react for 4h. Then, the temperature is lowered and steam is passed through, and the by-product is hydrolyzed to obtain 1-naphthalenesulfonic acid Chemicalbook. After the hydrolysis is completed, the materials are injected into the polycondensation kettle, 37% formaldehyde aqueous solution is added, and the reaction is carried out under a pressure of 196kPa. Finally, add alkali to neutralize to pH 8-10. The reaction is over. Cool and crystallize, filter out the crude product and dry it as the finished product.
