  • Empirical formula: C12H9NS
  • Weight: 199.273

Achieving the highest performance

WeylChem Allessa is the world’s largest producer of Phenothiazine Prills, an amine-based radical scavenger with versatile functionality as a monomer stabilizer for unsaturated compounds, antioxidant, and building-block in pharmaceutical synthesis.

Our prills offer optimal processing quality and improved stability in storage and handling and can be used at high temperatures and under oxygen-free conditions.

  • Benefits
  • Advantages of prills vs. flakes
  • Applications
  • Technical specification
  • Chemical Formula
  • Improved solubility in acrylic acid and acrylates
  • Optimal processing quality
  • Improved storage
  • Easier handling and dosage control
  • Reduction in dust
  • Uniform particle size gives improved solubility in acrylic acid and acrylate production
  • Greater bulk density liberates more storage space
  • Spherical shape and low dust content significantly reduce stickiness of material
  • Less – no sticking properties result in easier handling and better dosage control while feeding the production unit
  • Significant reduction in dust. Prills leave our production dust-free. A small amount of dust is nevertheless caused during transportation due to mechanical abrasion

Applications in the chemical and pharmaceutical industries

  • Monomer stabilizer for unsaturated compounds (monomers), protecting them from uncontrolled polymerization. The addition of 200 – 3000 ppm of phenothiazine is sufficient in most cases to inhibit premature polymerization of acrylic acid, methacrylic acid, acrylates, and vinyl compounds and thereby increases their stability during production and storage.
  • Antioxidant increasing the lifetime of synthetic rubber (chloroprene) and synthetic lubricating oils in order to improve their durability.
  • Building-block in pharmaceuticals synthesis or as an API in veterinary medicine.
