Hazardous Reagents

Through years of experience in the use of such hazardous and odorous materials such as carbon disulphide and mercaptans, Robinson Brothers Ltd has built both the expertise and containment facilities to handle a wide range of problematic and challenging materials on a commercial scale.

  • Thiocarbonylation with carbon disulphide
  • Thiolation with hydrogen disulphide
  • Reactions using chlorosulphonic acid
  • Sulphur chloride reactions thionyl, sulphuryl and sulphur chloride
  • Hydrogenation and high pressure reactions
  • Bromination
  • Phosgenation
  • Gas Odorants
  • Methylations using Dimethyl Sulphate
  • Organometallic chemistry with butyl lithium
  • Reactions with Hydroxylamine
  • Diazonium reactions
  • Friedel-Crafts reactions using bromotrifluoride (BF3) and aluminium chloride as catalysts
  • Diels Alder reactions using semi-bulk butadiene
  • Pilot Plant scale experience of Grignard reagents and hydrazine

Bromination & Phosgenation

Phosgenation PlantDedicated facilities for handling bromine and phosgene were installed in the early 1990's. In both cases, the technology was installed against specific enquiries for multi-stage custom synthesis. This meant that RBL could both expand its technical portfolio and take on the total synthesis for the customer. Today these technologies are offered typically as part of multi-step processes.

Brominations and phosgenations are carried out in dedicated 1400L glass lined reactor vessels, giving a variable scale up to a capacity of 50tonnes per annum. Each reactor has its own purpose built emission, abatement, control and electronic detection monitoring system so that the process is operated to the highest level of safety.
