CSTR in Series

Specifications

Continuous Stirred Tank Reactors in series (CSTR)

Saponification of an ester:

The saponification of ester with a strong base is a second order reaction. For example ethyl acetate react with sodium hydroxide to produce sodium acetate and ethyl alcohol. The equation is written as
CH3COOC2H5 + NaOH  ==  CH3COONa  + C2H5OH

Main  Unit Comprising of the following components:

a) Bench
A space saving bench constructed from chemically resistant worktop. Stainless steel 304, gauge 16. 40”*36”*60”
b) Reactors
3 units of 1-L vessels made of borosilicate glass / acrylic. Each vessel comes with stirrer system. Flow between each vessel is by gravity. Conductivity sensors are also provided for each vessel.
c) Stirrer System
Variable speed motor; with speed controller and indicator; stainless steel impeller.
d) Feed Tanks
35-L cylindrical tanks; material: stainless steel 304, gauge 16
e) Feed Pumps
Capacity: max. 15 LPM
f) Liquid Flowmeter
Range: 0 to 500 ml/min

Experimental Study:

  1. To find the effect of initial molar concentration (Cao) of a key component for a given reaction in the lab under the isothermal conditions (constant density system) on the size, space time & space velocity of continuous stirrer tank reactor.
  2. To find investigate the effect of flow rate on conversion, space time & space velocity.
  3. To study the effect of volume of reaction mixture on conversion, space time & space velocity for continuous stirrer tank reactor (CSTR).
  4. To study the effect of temperature on the rate of reaction.
