Chemical Properties
Tamol NH 7519 is a brown powde，soluble in water, resistant to acid, alkali and hard water.
Annd Tamol NH 7519 has good diffusivity and excelllent resistant to high temperatures than NNO.
Tamol NH 7519 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] .
