Gas-phase synthesis reactions
We specialize in gas-phase reaction using proprietary catalysts, as well as our advanced R&D capabilities, to become a manufacturer specializing in gas-phase reactions driven by advanced technology. Schema 1 below is a typical use of a gas-phase reaction to produce nitrogen-containing heterocyclic compounds (pyridine bases, pyrazines, pyrroles), and Schema 2 describes a process of ammoxidation.
Scheme 1:
synthesis of nitrogen-containing compounds using gas-phase reactions
Scheme 2:
ammoxidation
In addition, the gas-phase catalytic reaction shown below allows for producing items to clients’ needs.
By synergistically using our multi-purpose gas-phase plant, high pressure reaction equipment, and/or liquid-phase multi-purpose reaction equipment, we can build production workflows tailored to a range of clients.
