PIGNAT 50 L Multi Purpose Stainless Steel Reactor – OTP-RPI




Chemical engineering refers especially to chemical reaction engineering. Indeed, chemical reactions, catalyzed or not, are at the heart of all industrial syntheses.  Study of a chemical reaction, in a perfectly‐stirred reactor, permits the operator to understand the influence of the different parameters in the optimization of the chemical synthesis with a view to its industrialization.

Carry out operations of fine chemistry products synthesis

Perform and study reactions:

  • Esterification or saponification
  • Concentration by evaporation
  • Crystallization by cooling

Knowledge of reaction’s characteristics:

  • Basic, aqueous, organic, mineral medium
  • Endo or exothermic reaction
  • Bi-phase catalytic reaction

Carrying out of an operation depending on operating conditions:

  • Working pressure: atmospheric or vacuum
  • Monitoring of cooling during crystallization
  • Management of the distillation with reflux ratio definition

Proposed experiments:

  • Butyl acetate esterification.
  • Separation of reaction products by distillation and decantation.
  • Calculation of reaction output.
  • Calculation of mass balances.
