CEB-MKIII Transparent Batch Reactor Didactic Equipment Vocational Training Equipment Chemical Engineering
DESCRIPTION The CEB-MkIII Transparent batch reactor is a double-skinned glass vessel with a one-litre internal working volume, fitted with a variable-speed agitator. Hot water from the CEXC or cold water from the CW-17 can be circulated through the jacket for temperature control purposes maintaining the reactor contents at constant temperature. Glands in the clear acrylic lid allow the CEXC conductivity and temperature probes to be fitted to facilitate monitoring of the reactions in progress such as the important saponification reaction. Isothermal and adiabatic operation reactions may be demonstrated. (Note, the isothermal reaction requires theCW-17 accessory if experiments at low temperature are to be studied or if the ambient temperature is high). For adiabatic operation, the use of dyes enables the chemical reaction rates to be monitored visually by the change in colour at different degrees of conversion. EXPERIMENTAL CONTENT Isothermal Operation – To Determine the reaction rate constant in a stirred batch reactor Adiabatic Operation – To determine the rate equation for the hydrolysis of acetic anhydride to acetic acid in an adiabatic reactor. Investigation of the effect of reactant concentration on the reaction rate Investigation of the effect of temperature on conversion Visual monitoring of the chemical reactions Study of the temperature variation of an exothermic reaction on an adiabatic operation Note: CEB-MkIII is designed for use with the CEXC service unit. CEB-MkIII can be used with the CEX service unit, but an additional STS5 temperature sensor will be required for complete functionality.
