Welcome to the BTL New Material Case Study gallery. Since 2020, we have been a leading Chinese supplier of high-purity manganese compounds. This section showcases our expertise in solving complex chemical challenges across the water treatment, battery manufacturing, and pharmaceutical industries. Discover how our customized Manganese Dioxide (MnO₂), Manganese Carbonate (MnCO₃), and Manganese Sand help global clients achieve superior performance and cost-efficiency.

• Client Profile
  • A leading specialty chemical manufacturer based in France.
  • Specializing in high-end pharmaceutical intermediates and complex organic synthesis.
• The Challenge
  • High Material Loading: The existing process required a large excess of technical-grade MnO₂ (approximately 13 equivalents).
  • Reproducibility Issues: Variations in surface area and impurity profiles of standard grades led to inconsistent reaction kinetics.
  • Operational Inefficiency: High loading increased solid waste generation, filtration time, and overall production costs.
• Our Solution
  • High-Purity Material: Supplied Activated Manganese Dioxide with an assay of ≥ 99.0%.
  • Amorphous Structure: Recommended amorphous MnO₂ to provide a higher density of lattice defects for enhanced surface reactivity.
  • Dual-Grade Strategy: Provided two particle size options for High Throughput Experimentation (HTE): Grade A (D50 ≈ 2 μm) for maximum activity and Grade B (D50 ≈ 6 μm) for better filtration.
• Technical & Purity Advantages
  • Strict Impurity Control: Limited iron content to Fe ≤ 400 ppm and strictly controlled alkali/alkaline earth metals.
  • Optimized Kinetics: The amorphous morphology was specifically selected to accelerate the dehydrogenation pathway under toluene reflux.
• The Result
  • Successful Scale-up: The project transitioned from laboratory screening to industrial collaboration with an initial 1-ton trial order.
  • Improved Atom Economy: Achieved the R&D objective of significantly reducing MnO₂ equivalents (loading).
  • Enhanced Process Stability: Provided consistent material morphology, ensuring reproducible results for large-scale manufacturing.
