WebMar 21, 2024 · The cumene process scheme that AAAIK is using is not based on the modern liquid phase reaction over zeolite catalyst, but on the old high temperature vapor phase reaction over (presumably) SPA catalyst. It originates from Turton's book and is used by others who sometimes made changes to it in order to "optimize" the process. Cumene (isopropylbenzene) is an organic compound that contains a benzene ring with an isopropyl substituent. It is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of 152 °C. Nearly all the cumene that is produced as a pure compound on an industrial scale is converted to cumene hydroperoxide, which is an intermediate in the synthesis of other industrially important chemicals, primarily phenol and acetone (known as the cumene process
