Hazard Information | Back Directory | [Description]
Sodium poly[(naphthaleneformaldehyde)sulfonate] is a brown powde,soluble in water, resistant to acid, alkali and hard water. Annd it has good diffusivity and excelllent resistant to high temperatures than NNO. Sodium poly[(naphthaleneformaldehyde)sulfonate] is commonly used as dispersant and filler of scattered dyes, reactive dyes, pesticides, leather tanning agent, also water reducing agent for construction and oil well. | [Chemical Properties]

Annd it has good diffusivity and excelllent resistant to high temperatures than NNO. Sodium poly[(naphthaleneformaldehyde)sulfonate] is commonly used as dispersant and filler of scattered dyes, reactive dyes, pesticides, leather tanning agent, also water reducing agent for construction and oil well. | [Uses]
Used as a diluent for pulp control in the paper industry, reducing duplexity, improving filler or fines retention, improving sizing, and reducing coating viscosity. Used as a high-efficiency dispersant for water-based coatings and pigment pastes. Used as an adhesive, improve water resistance of filler powder andsealing layers. | [Synthesis]
The solution of naphthalene(550kg)was heated at 50°C for 4h in the reaction kettle. Then cool down and pass water vapor to hydrolyze the by-product to give 1-naphthalenesulfonic acid. After the hydrolysis is completed, formaldehyde (37%) is added under 196kPa. Finally, alkali is added to neutralize to pH 8-10. The mixtrue was cooling and crystallization,and filtered out to give the product, Sodium poly[(naphthaleneformaldehyde)sulfonate] . |
