Consider the molten salt loop for removal of the heat of reaction in the production of phthalic anhydride described in Appendix C (on the CD) and illustrated in Figure C.5. It is necessary to scale down phthalic anhydride production by \(50 \%\). Estimate the flow of molten salt for the scaled-down case and the temperatures of molten salt entering and exiting the reactor. You may assume that sensible heat effects (energy necessary to heat reactants to reaction temperature) are negligible.
