Flow Chemistry
Most of the chemicals made for the fine or specialty chemical industry are made in batch.
Flow chemistry is the solution to optimize production for fine and specialty chemical industry.
KHIMOD’s offer for flow chemistry
Is flow chemistry an option for you?
Is the chemical reaction very exothermic or endothermic with a risk on safety or product quality?
Flow chemistry enables to manage safely very exothermic reactions thanks to an outstanding thermal exchange
Do you face an issue with yield, selectivity or purification in batch process?
Flow chemistry can be a solution when impurities or low yield are coming from a weak control of the temperature or reaction time
Will the chemical reaction generate precipitates?
Challenging but KHIMOD can be the solution, with our patented technology coupling our reactor and ultrasounds
Do you need to use some gas such as H2, O2, NH3, HF, Phosgene or Phosphine?
Handling gases, specially at high pressure, is challenging in batch but can be performed safely in flow
Does your reaction involve hazardous intermediates?
Flow chemistry enables to handle very hazardous intermediates safely by reducing the reactive volume
Is the reaction too slow and speed can be boosted at higher temperature or pressure?
By using flow chemistry and process intensification approach, reaction time can be dramatically reduced
Is the reaction very slow, even at high temperature or pressure?
Flow chemistry is not an option
Key Benefits
