Advanced metathesis meets high-end downstream chemistry
At Saltigo, we combine cutting-edge metathesis technology with advanced downstream processing — the ideal solution for companies involved in the synthesis of complex molecules. Leveraging the expertise we’ve built in recent years and utilizing state-of-the-art catalysts, we ensure outstanding product quality and selectivity.
Integrated oxygen sensors in the exhaust system provide additional safety when handling highly flammable ethylene.
Innovative charge systems used for the safe and efficient use of highly active catalysts, even at a scale of 12 m³.
Optimized for both efficiency and selectivity
Our processes are based on two primary catalyst systems:
- Ruthenium-based (Grubbs) catalysts
- Tungsten/Molybdenum-based (Schrock) catalysts
Ru-based systems offer economic advantages but require the careful removal of ruthenium residues, for example through specialized ion exchange resins (from our sister BU LPT).
In contrast, Schrock catalysts stand out for their superior selectivity, enabling excellent product quality, though they are more cost-intensive in use.
Metathesis also plays a key role in the production of bio-based raw materials, which are further processed into specialty chemicals — including pheromones, where metathesis technology is used as a central step.
Saltigo offers the ideal downstream infrastructure to support the purification and separation steps required for these innovative, sustainable products.
