Our dedicated phosgenation lab enables safe and efficient development of complex phosgene chemistry under controlled conditions:
- Reactors ranging from 0.5 to 10 liters
- Phosgene supply from cylinders
- Capability for liquid-phase phosgenation
- Direct scale-up from lab to production in our plant at the Dormagen site
Saltigo operates its own phosgene production unit, ensuring reliable supply and integration into full-scale processes. We offer broad expertise in the synthesis of phosgene-based intermediates, including:
- Chloroformates
- Acid chlorides
- Ureas
- Isocyanates
- Carbonates
Our phosgenation processes are seamlessly connected to a wide range of downstream chemistries, enabling the synthesis of custom-made products, such as through:
- Alkylation reactions
- Condensation reactions
- Chlorinations
- Reductions
- Organometallic transformations
Saltigo’s phosgene operations are supported by modern, flexible equipment designed for both continuous and batch production, including:
- Reactor trains made from glass-lined steel, stainless steel and Hastelloy
- Post-processing units such as distillation columns, pressure nutsches, filter dryers, centrifugal dryers and thin-film evaporators
- Multiple filling stations for tank trucks, ISO containers and rail tank cars
- Closed systems for safe filling of drums and IBCs
- On-site tank farms for safe storage of intermediates and final products
Safety is Saltigo’s top priority — especially when handling highly reactive substances like phosgene. This is ensured through a comprehensive safety approach, including:
- Purpose-built facilities with physically separated areas for phosgene chemistry (e.g. outdoor process units)
- Redundant process instrumentation to detect and control deviations reliably
- Use of inert heating and cooling media
- Separate exhaust treatment systems for phosgene-containing off-gases
- Multi-level phosgene monitoring, including area sensors on production platforms
