Q: What is the primary industrial method for sodium hydroxide synthesis?
A: The primary method is the chlor-alkali process, which involves electrolyzing sodium chloride (NaCl) solution. This produces sodium hydroxide (NaOH), chlorine gas (Cl₂), and hydrogen gas (H₂).
Q: How does free-radical polymerization work in polyacrylamide synthesis?
A: Free-radical polymerization initiates with a catalyst (e.g., ammonium persulfate) generating radicals. These radicals react with acrylamide monomers, forming long polymer chains. The process is temperature- and pH-sensitive.
Q: Can sodium hydroxide be synthesized in a lab without electrolysis?
A: Yes, by reacting sodium metal with water: 2Na + 2H₂O → 2NaOH + H₂. However, this method is less practical for large-scale production compared to industrial electrolysis.
Q: What are key uses of polyacrylamide in industrial applications?
A: Polyacrylamide is widely used as a flocculant in wastewater treatment and soil stabilization. It also enhances oil recovery in petroleum extraction by modifying fluid viscosity.
Q: What factors influence polyacrylamide's molecular weight during synthesis?
A: Monomer concentration, initiator type, and reaction temperature are critical. Higher monomer concentrations and controlled temperatures typically yield higher molecular weights.
