Polyacrylatesodium Aq CAS 9003-04-7 Water Treatment
Sodium polyacrylate (CAS 9003-04-7) is the sodium salt of polyacrylic acid. As a chemical polymer, it has diverse applications in consumer products due to its exceptional water absorption capacity, capable of absorbing 200-300 times its mass in water.
Property
Description
Dispersant Applications
Widely used as a dispersant in power plants, chemical plants, fertilizer plants, refineries, cooling water systems, paper and textile industries, ceramics, paints, and building materials. Effective for descaling and preventing precipitation in various industrial systems.
Key Characteristics
Sodium polyacrylate appears as a colorless or light yellow viscous liquid at room temperature. It is non-toxic, alkaline, insoluble in organic solvents like ethanol , but readily soluble in water and aqueous sodium hydroxide.
Molecular Properties
This water-soluble linear polymer exhibits varying physical forms based on molecular weight. Low molecular weight variants are liquid, while higher molecular weight forms appear as white powder or granules. The material is odorless, water-swellable, soluble in aqueous caustic soda, and extremely hygroscopic.
Food Grade Applications
Approved as a food grade thickener in China since 2000, sodium polyacrylate serves multiple functions in food processing:
Enhances adhesion to raw flour protein and improves dough texture
Provides strong water-holding capacity to prevent drying
Improves dough extensibility and stabilizes oil component dispersion
Acts as electrolyte for protein interaction, enhancing food viscoelasticity
Specific Food Applications
Bread, cakes, noodles, macaroni (0.05% usage for improved taste and raw material utilization)
Fish paste products, canned food, dried seaweed (strengthens organization and preserves flavor)
Frozen food, aquatic products (surface jellies for preservation)
Usage Limitation: According to GB 2760-2000 standards, maximum usage in various foods is 2.0 g/kg. Japan limits maximum amount to 0.2% (1993).
Safety Profile
Toxicity: LD50 > 10g/kg (mice oral). Subacute testing showed no exceptions in rats at 0.5g/kg/day for 6 months.
Industrial Applications
Corrosion scale inhibitor and water stabilizer
Paint thickener and water retention agent
Flocculant for water treatment
Drilling mud treatment agent
Filtrate reducer in solid drilling industry
Anion detergent and dispersant for oil field water, cooling water, and boiler water treatment
Production Methods
Primary production involves reaction of acrylic acid with sodium hydroxide to form sodium acrylate, followed by polymerization using ammonium persulfate as catalyst. The process includes concentration, pH adjustment, and may involve spray drying for solid product formation.
Chemical Description: Sodium polyacrylate, also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [-CH2-CH(COONa)-]n. It functions as an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain.
