Consider ethyl-tertiary-butyl-ether (ETBE) as an alternative gasoline oxygenate to MTBE. Although the latter appears to have the best combination of properties such as oxygen content, octane number, energy content, and cost, the former can be manufactured using ethanol according to:

\[\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\text { iso-butene } \rightleftharpoons \mathrm{ETBE}\]

Because ethanol can be manufactured from biomass, it is potentially more acceptable to the environment.

(a) Rework Example 6.1 for this process.

(b) Is reactive distillation promising for combining the reaction and separation operations? If so, suggest a distribution of chemicals using a reactive distillation operation.

This example involves the synthesis of a process to hydrodealkylate toluene, which was actively used following World War II, when it became favorable to convert large quantities of toluene, which was
