Chemical Properties
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.
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] .
Check Digit Verification of cas no
The CAS Registry Mumber 9084-06-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,8 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 9084-06:
(6*9)+(5*0)+(4*8)+(3*4)+(2*0)+(1*6)=104
104 % 10 = 4
So 9084-06-4 is a valid CAS Registry Number.
