Expertise

Bucher specializes in the following reaction technologies:

  • Production of Silanes with highly reactives leaving groups (amido, amino, enolate, etc.)
  • Handling of Sodium Metal on a scale of >100 tons per year
  • Large Scale Use of Metal reagents (NaH, Buli, Hexli, LAH, LiH, etc.)
  • Grignard-Chemistry
  • Handling and Production of Materials that require special handling due to their properties (toxic, corrosive, smelly, highly flammable, highly reactive or sensitive to moisture/oxygene, etc.)

Silicon Specific Expertise:

  • Removal of Chloride from Silanes that are sensitive to water (different removal technologies)
  • Production to highly sensitive Silanes like:
  • Amidosilane (BSA, BSTFA, MSTFA, etc.)
  • Silyl enol ethers
  • Silyl amines (TMSDEA, TMSDMA, etc.)
  • Silyl triflates and (pseudo-)halogenids
  • Manufacturing of room temperature stable and pure (up to 99%) Trimethylsilanol
