Cumene(98-82-8) is an organic compound that is an aromatic hydrocarbon. It is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of 152 °C.
Uses
Production
Cumene(98-82-8) is manufactured by reacting benzene with propylene over a catalyst such as a phosphoric acid derivative at 175 to 250 °C and 400 to 600 psi. A refinery cut of mixed propylene-propane is frequently used instead of the more expensive pure propylene. Benzene is provided in substantial excess to avoid polyalkylation. The yield is near quantitative (in excess of 90 percent) based on propylene.
C6H6 + CH3CH=CH2 → C6H5CH(CH3)2
Excess benzene stops the reaction at the monoalkylated stage and prevents the polymerization of propylene. The cumene(98-82-8) is separated by distillation, boiling point 153 °C . Other catalysts that have been used are aluminum chloride and sulfuric acid.
