C 6 H 5 C(CH 3) 2 O 2 H → C 6 H 5 C(O)CH 3 + CH 3 OH. The cumene process is conducted on such a large scale that even the small amount of acetophenone by-product can be recovered in commercially useful quantities. [2] Acetophenone is also generated from ethylbenzene hydroperoxide.
Cumene hydroperoxide is the organic compound with the formula C 6 H 5 C(CH 3) 2 OOH. An oily liquid, it is classified as an organic hydroperoxide. [2] Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and 2-phenyl-2-propanol. [3] It is produced by treatment of cumene with oxygen, an autoxidation.
Most of the worldwide production of phenol and acetone is now based on this method. In 2022, nearly 10.8 million tonnes of phenol was produced by the cumene process. [4] In order for this process to be economical, there must also be demand for the acetone by-product as well as the phenol. [5]
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
clc 5 h 4 chcl 2 + h 2 o → clc 5 h 4 cho + 2 hcl It can also be produced by the oxidation of 4-chlorobenzyl alcohol . [ 3 ] [ 4 ] It can be further oxidized to 4-chlorobenzoic acid . [ 5 ]
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).
