The Chemical Reaction Technologies Unit provides ICIQ researchers with technical support in chemical reaction development, specially in reaction parallelization and high throughput synthesis, reaction scale-out, in situ reaction monitoring, high pressure reactions and reactions performed in microflow reactors.
In the field of chemical parallelization, the unit has equipment to perform all the unit operations involved in a chemical process: reaction, work-up, purification and final isolation of the product.
A chemical reaction can be scaled up in a fully computer controlled reactor, from 0.6 to 6 L. This scale is optimal for preparing in-house starting materials and for technology transfer in cooperation projects.
In situ reaction monitoring can be performed by FTIR and NMR using the HPIR reactor, the HPNMR tube or Polychrome V. These techniques are non-intrusive and are very useful for kinetic and mechanistic studies.
Moreover the unit provides ICIQ researchers with different technologies to perform reactions under singular conditions such as a microwave reactor, a photochemical reactor and a set of microflow reactions.
