Product Description: Sodium Dimethyl Dithiocarbamate is a versatile organic sulfur compound with applications across various industries. Its roles include usage as a fungicide, pesticide, and a critical intermediate in pharmaceutical synthesis. Additionally, it serves as a stepping stone in producing other dithiocarbamates and rubber chemicals.

Key Features:

• Versatility: Applicable in agriculture, pharmaceuticals, and chemical synthesis.
• Efficiency: Highly effective as a biocide for controlling fungal growth and as a pesticide.
• Safety: Must be handled with care due to its potential toxicity.

Applications:

• Mining Flotation:

  • SDMDTC acts as a collector in the froth flotation process, enhancing the separation of valuable minerals from waste rock (gangue). Its metal ion complexation capability aids in selectively floating certain ores.

• Fly Ash Treatment:

  • For coal combustion byproducts, SDMDTC immobilizes heavy metals in fly ash, reducing their environmental impact and making the fly ash suitable for cement production or soil amendment.

• Heavy Metal Treatment:

  • Thanks to its chelating properties, SDMDTC forms stable complexes with heavy metals, facilitating their removal from industrial wastewater and contaminated soils during environmental remediation.
  • Cobalt Removal in Zinc Smelting (Hydrometallurgy):
    • In zinc hydrometallurgy, SDMDTC selectively extracts cobalt from zinc sulfate solutions, aiding in the purification process and allowing recovery of cobalt as a valuable byproduct.
    • The selective complexation of cobalt by SDMDTC enables its separation from zinc, streamlining the purification process and enhancing the overall efficiency.

• Agricultural Soil Treatment:

  • SDMDTC is invaluable in remediating soils contaminated with heavy metals, reducing their bioavailability and mobility through complex formation.

• Industrial Wastewater Treatment:

  • In industrial applications, SDMDTC treats wastewater containing heavy metals, ensuring compliance with regulatory discharge standards.

Safety Information:

• Wear appropriate personal protective equipment (PPE) when handling SDMDTC.
• Avoid inhalation, ingestion, and skin contact. Ensure usage in a well-ventilated area.

Storage Conditions:

• Store in a cool, dry place, away from heat and direct sunlight. Ensure that the storage environment is optimal to preserve the quality and efficacy of the product over time.
• Keep container tightly sealed to maintain product integrity. A tightly sealed container will help prevent contamination and degradation, ensuring the product remains effective for its intended use.
