    Sodium Glucoheptonate CAS 31138-65-5

    Sodium Glucoheptonate CAS 31138-65-5 is a highly stable organic sequestering agent that provides exceptional metal ion control in high-alkalinity environments. Within industrial water treatment and metal surface processing, this sodium glucoheptanoate functions as a primary chelating agent capable of forming non-ionic, water-soluble complexes with polyvalent metal ions like calcium, magnesium, and iron. This sodium gluceptate is particularly valued for its caustic stability in alkaline bottle washing and textile mercerizing processes, while glucoheptonic acid sodium salt prevents iron staining and mineral scale buildup in high-pH industrial cleaning formulations. As a biodegradable alternative to EDTA, this sodium alpha-glucoheptonate facilitates efficient aluminum etching and cement set retardation without environmental bioaccumulation. We provide bulk supply with competitive factory pricing to support large-scale industrial operations, ensuring all shipments are verified via MSDS, TDS, COA and offer customized specifications for liquid or crystalline powder forms.

    Applications

    • Industrial Cleaning: Used in heavy-duty alkaline cleaners for bottle washing, food processing equipment, and metal degreasing to prevent scale and complex metal contaminants.
    • Textile Industry: Applied as a sequestering agent during bleaching and mercerizing to improve dye uptake and prevent metal-induced fiber degradation.
    • Construction Chemicals: Acts as a high-efficiency set retarder in concrete and oil-well cement formulations to extend workability and improve compressive strength.
    • Water Treatment: Serves as a green chelating agent for scale and corrosion inhibition in boilers, cooling towers, and heat exchangers.

    Storage & Safety

    • Storage: Store in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials like strong oxidizing agents. Keep containers tightly closed when not in use.
    • Safety Operations (PPE): Wear standard industrial safety glasses with side shields and chemical-resistant gloves (nitrile or PVC). Use a dust mask if handling the powder form in non-ventilated areas.
    • Handling: Prevent contact with eyes and prolonged skin contact. Wash hands thoroughly after handling. The liquid form can be slippery; manage spills promptly with absorbent materials.

    Quality Assurance

    Our manufacturing process for Sodium Glucoheptonate utilizes high-purity sugar-based precursors and controlled oxidation to ensure a consistent isomer profile. Each batch undergoes rigorous testing via Nonaqueous Titration for assay verification and ICP analysis for trace metal monitoring. We strictly adhere to ISO 9001 standards to ensure that our product meets the sequestration capacity requirements of global industrial cleaning and construction benchmarks.

    FAQ - Technical & Supply Chain

    • Q:

      How does the CAS 31138-65-5 designation confirm the chemical identity for industrial procurement?

      A: CAS 31138-65-5 is the standard identifier for Sodium Glucoheptonate, a seven-carbon sugar acid salt. It is chemically distinct from the six-carbon Sodium Gluconate (CAS 527-07-1), offering significantly higher chelating efficiency for trivalent ions like Fe3+ and Al3+ in solutions where the pH exceeds 12.
    • Q:

      Why is Sodium Glucoheptonate preferred over EDTA for textile and water treatment applications?

      A: This material is typically applied as a biodegradable and non-toxic alternative to EDTA. Unlike synthetic aminopolycarboxylates, Sodium Glucoheptonate is readily biodegradable and does not present the same environmental persistence or heavy metal mobilization risks in wastewater systems, while maintaining superior stability in high-caustic formulations.
    • Q:

      Is this product suitable for use in high-concentration caustic soda solutions?

      A: Yes, Sodium Glucoheptonate is intended for use in concentrated alkaline systems. It remains chemically stable and maintains its sequestering power in caustic soda concentrations up to 10-20%, making it the ideal additive for industrial bottle washing and metal etching processes where other chelating agents might decompose.
