Acetic acid (CH3COOH) is chlorinated in a continuous reactor producing monochloroacetic

acid (CH2ClCOOH) in the following reaction:

CH3COOH + Cl2 CH2ClCOOH + HCl

Some of the product monochloroacetic is converted to dichloroacetic acid (CHCl2COOH) in

the undesired side reaction as follows:

CH2ClCOOH + Cl2 CHCl2COOH + HCl

The feed to the reactor contains 80 kmol/h acetic acid and 63.98 kmol/h of Cl2. The product

leaving the reactor contains 52.91 kmol/h monochloroacetic acid, 2.04 kmol/h dichloroacetic

acid, HCl, and some unreacted acetic acid and Cl2.

(a) Draw and completely label the process flowchart for this process.

(b) Using the extent of the reaction method, determine the flow rate of the HCl and

unreacted acetic acid and Cl2 leaving the reactor.

(c) Determine the conversion of acetic acid (%), and the yield (%) and selectivity of

monochloroacetic acid.
