CUMENE PROCESS Meaning and
Definition
-
The cumene process is a chemical engineering method for producing phenol and acetone, which are essential chemical intermediates used in the manufacturing of numerous products. This process involves the selective oxidation of cumene, an organic compound derived from benzene and propylene, to generate these two valuable substances.
In the cumene process, cumene is first mixed with air and fed into a reactor vessel. Inside the reactor, the cumene is catalytically oxidized, usually with the help of an acid catalyst such as aluminum chloride or phosphoric acid. This catalytic reaction transforms the cumene molecules, breaking them down and rearranging their chemical structure. The result is the production of phenol and acetone as byproducts.
Following the reaction, the phenol and acetone undergo a separation process to isolate them from other components and impurities. This involves various techniques such as distillation and extraction to obtain purified phenol and acetone. These chemicals are then utilized in numerous applications, including the manufacturing of plastics, resins, synthetic fibers, pharmaceuticals, and disinfectants.
The cumene process has found widespread industrial use due to its efficiency and ability to produce large quantities of phenol and acetone. It offers a key method for the commercial production of these critical chemical intermediates, providing the foundation for a wide range of industries and products.
Etymology of CUMENE PROCESS
The term "cumene process" is derived from the chemical compound "cumene" and the word "process".
The compound cumene, also known as isopropylbenzene, is an organic compound with the formula C9H12. It is a colorless liquid commonly used as a constituent of fuels and as a solvating agent. Cumene is produced commercially through the cumene process.
The cumene process is a method for manufacturing phenol and acetone from benzene and propylene. It involves the reaction of benzene with propylene, which creates cumene as an intermediate compound. The cumene is then oxidized to form phenol and acetone. This process was developed by Hock and Lang in the 1940s and is widely used in the chemical industry.
