Flash Pyrolysis Platform - Chemistry just got hotter

Small particles big efficiency or Vaporized Magical Synthesis or Modular Hot Synthesis

Faster, greener, wider chemistry

While a number of avenues are available to organic chemists for the synthesis of novel structures, it has also been shown that chemists employ a relatively small chemical technology toolbox that is limiting the potentially attainable chemical space, in conventional laboratories all around the world. It is especially true once extreme process conditions are applied in order to attain the desired, (in most cases novel) compounds.

In response to these limitations and needs we have developed and launched the Flash Pyrolysis system onto the market that reaches beyond the already known capabilities of the usual vacuum flash pyrolysis instruments by enabling one to apply non volatile starting materials as well, via our own interchangeable vaporizer system.

Therefore, the Flash Pyrolysis Platform is capable of handling both providing 2 interchangeable modes for its users:

- Flash Vacuum Pyrolysis Applications (FVP), and

- Continuous Liquid Spray Vaporization (CLSV) applications too.

Advantages:

  • Simple: Easy to use
  • Interchangeable: smooth change between pyrolysis and spray modes
  • Precise: Separate heating for the reactor and the pre-heater
  • Powerful: Volatile and non-volatile materials can be reacted
  • Efficient: Extremely high temperature, reaction time in less than 1 sec
  • Greener chemistry: solvent free reactions

Flash Vacuum Pyrolysis:

During the course of the FVP applications, the system is kept under vacuum, while the starting material is introduced mostly in a micronized solid state. Due to the applied conditions (high temperature, and vacuum) the FVP applications facilitate the occurrence of mostly unimolecular reactions where the materials (in gas phase) pass through the reactor in range of milliseconds.

In FVP mode, the starting material is distilled through the furnace in a quartz reactor tube, while it is exposed to pyrolytic conditions in the furnace under vacuum. The precursor sublimates through the system by a pre-heater that is mounted onto the furnace, and the products are then condensed by cold traps afterwards.

Apart from the fact that the vacuum may avoid adverse chemical reactions, it may also decrease the boiling point of the precursors in the pre-heater, helping the starting material to be sublimated through the system too.

In the case of the CLSV methods however, the starting material is molecularly dispersed in a chosen solvent that is sprayed through the system, and it does not require the presence of a vacuum during the course of the applications. In this case, we do not use vacuum.

In CLSV mode the applications do not require the presence of a vacuum, and it does not require the substrate to be volatile, as it is dissolved and sprayed through the reactor tube via a nozzle under continuous nitrogen flow. Finally the samples are then collected using similar cold traps.
