Description:
This pilot plant concerns the batch reaction; the study of kinetics is carried out versus the variation of conductivity in the
reactor. This reactor includes a cooling jacket, an electric heater and a distillation column with variable reflux condenser
and azeotropic separator. The automated version is equipped with PID controller for the automatic control of reaction
temperature and of the stirrer rpm.
TRAINING PROGRAM
This unit enables to deepen the following issues:
• Determination of reaction kinetics
• Reaction thermodynamics
• Mass and energy balance
• Automatic temp. & rpm control with PID controller
• Plant supervision by P.C.
• Exercises than can be carried out:
– kinetics of hydrolysis of ethyl acetate
– preparation of p-Toluensulfonic acid
– preparation of diethyl adipate
– reaction of urea with nitrous acid
– preparation of cyclohexanonoxime from hydroxylamine sulfate and cyclohexanone
– transformation of acetic anhydride into acetic acid and display of reaction kinetics by measurement of conductivity
– preparation of amide.
