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.
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), C 10 H 14 O, is a natural monoterpenoid phenol derivative of p-Cymene, isomeric with carvacrol.It occurs naturally in the oil of thyme, and it is extracted from Thymus vulgaris (common thyme), ajwain, [4] and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties.

Diisopropylbenzenes typically arise by alkylation of benzene or isopropylbenzene with propylene: C 6 H 6 + CH 3 CH=CH 2 → C 6 H 5 CH(CH 3) 2 C 6 H 5 CH(CH 3) 2 + CH 3 CH=CH 2 → C 6 H 4 (CH(CH 3) 2) 2. These alkylations are catalyzed by various Lewis acids, such as aluminium trichloride. They can also be prepared and transformed by ...

This latter cumene converts into cumene radical and feeds back into subsequent chain formations of cumene hydroperoxides. A pressure of 5 atm is used to ensure that the unstable peroxide is kept in liquid state. Cumene hydroperoxide undergoes a rearrangement reaction in an acidic medium (the Hock rearrangement) to give phenol and acetone. In ...
In addition to p-cymene, two less common geometric isomers are o-cymene, in which the alkyl groups are ortho-substituted, and m-cymene, in which they are meta-substituted.
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...
