Chlorobenzene (C6H5CI), an important solvent and intermediate in the production of many other chemicals, is produced by bubbling chlorine gas through liquid benzene in the presence of ferric chloride catalyst. 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 (98 wt% Cl2, the balance gaseous impurities with an average molecular weight of 25.0). The liquid output from the reactor contains 65.0 wt% C6H6, 32.0 wt% C6H5CI, 2.5 wt% C6H4CI2, and 0.5 wt% C6H3CI3. The gaseous output contains only HCl and the impurities that entered with the chlorine. (a) You wish to determine (i) the percentage by which benzene is fed in excess, (ii) the fractional conversion of benzene, (iii) the fractional yield of monochlorobenzene, and (iv) the mass ratio of the gas feed to the liquid feed. Without doing any calculations, prove that you have enough information about the process to determine these quantities. (b) Perform the Calculations

Question
Transcribed Image Text:Chlorobenzene (C6H5CI), an important solvent
and intermediate in the production of many
other chemicals, is produced by bubbling chlorine
gas through liquid benzene in the presence of
ferric chloride catalyst. 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 (98 wt% Cl2, the balance gaseous
impurities with an average molecular weight of
25.0). The liquid output from the reactor contains
65.0 wt% C6H6, 32.0 wt% C6H5CI, 2.5 wt%
C6H4C12, and 0.5 wt% C6H3CI3. The gaseous
output contains only HCl and the impurities that
entered with the chlorine.
(a) You wish to determine (i) the percentage by
which benzene is fed in excess, (ii) the
fractional conversion of benzene, (iii) the
fractional yield of monochlorobenzene, and (iv)
the mass ratio of the gas feed to the liquid feed.
Without doing any calculations, prove that you
have enough information about the process to
determine these quantities.
(b) Perform the Calculations
