Basic Information and Parameters

The product in question is sodium p-styrenesulfonate with the CAS number 2695-37-6. It is supplied directly from the factory, ensuring high - quality and cost - effective pricing. Sodium p - styrenesulfonate is a white or off - white powder. It has a relatively stable chemical structure. The molecular formula of sodium p - styrenesulfonate is C₈H₇NaO₃S. Its molecular weight is approximately 206.2 g/mol. It is soluble in water, and the solubility may vary depending on factors such as temperature and pH. The purity of the factory - supplied sodium p - styrenesulfonate usually meets high - grade industrial standards, often reaching over 98%.

Uses of the Product

In the field of polymer chemistry, sodium p - styrenesulfonate is an important monomer. It can be copolymerized with other monomers such as styrene, acrylonitrile, etc., to produce various functional polymers. These polymers have excellent ion - exchange properties, which are widely used in ion - exchange resins for water treatment. In water treatment applications, they can effectively remove heavy metal ions, anions, and other impurities from water, thereby improving the quality of water.

In the paper industry, it can be used as a sizing agent. When added to the papermaking process, it can improve the strength, water resistance, and printability of paper. In the textile industry, it can be used in the modification of fibers. By grafting sodium p - styrenesulfonate onto the fiber surface, the antistatic and dye - affinity properties of the fiber can be enhanced.

How to Use the Product

When using sodium p - styrenesulfonate in polymerization reactions, it is necessary to first dissolve it in an appropriate solvent, usually deionized water. The concentration of the solution should be adjusted according to the specific reaction requirements. Generally, a concentration of 10% - 30% (by mass) is commonly used. Then, other monomers, initiators, and additives are added to the solution. The reaction temperature, time, and pH value need to be precisely controlled. For most polymerization reactions, the temperature is usually maintained between 50 - 80 °C, and the reaction time ranges from 2 - 6 hours.

In water treatment, sodium p - styrenesulfonate - based ion - exchange resins need to be properly packed in the ion - exchange column. Before use, the resin needs to be activated and regenerated according to the standard procedures. In the papermaking and textile industries, the product should be added at the appropriate stage of the production process, and the addition amount should be determined based on the production scale and quality requirements.

Usage Case Studies

Case 1: A water treatment plant in the United States used sodium p - styrenesulfonate - based ion - exchange resins to treat industrial wastewater containing heavy metal ions. Before treatment, the concentration of lead ions in the wastewater was as high as 50 mg/L. After passing through the ion - exchange column filled with the prepared resin, the lead ion concentration was reduced to less than 0.1 mg/L, which fully met the national discharge standards.

Case 2: A paper mill in China added sodium p - styrenesulfonate as a sizing agent during the papermaking process. After using the product, the paper's bursting strength increased by 20%, and the water absorption decreased by 30%. This not only improved the quality of the paper but also reduced the production cost.
