2. Chlorobenzene (CH,CI), an important solvent and intenmediate in the production of many
other chemicals, is produced by bubbling chlorine gas through liquid benzene in the presence
of ferric chloride cntalyst. In an undesired side reaction, the product is further chlorinated to
dichlorobenzene, and in a third reaction the dichlorobenzene is chlorinated to
trichlorobenzene. The feed to a chlorination reactor consists of essentially pure benzene and
a technical grade of chlorine gas (98wt% Cl, the balance gaseous impurities with an average
molecular weight of 25.)The liquid cutput from the reactor contains 65wt% CaHe 32wt%
CaH.CI; 2.5 wt%CHCI, and 0.5 wt% CeH,Cl . The gaseous output contains only HCl and
the impurities that entered with chlorine
Determine:
a) The percentage by which benzene is fed in excess
b) The fractional conversion of benzene.
c) The fractional yield of monochlorobenzene.
d) The mass ratio of the gas to liquid feed
