In Organic chemistry, a hydrocarbon is an Organic compound consisting entirely of Hydrogen and Carbon. 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 such as phenol and acetone. Phenol, is a toxic colourless Crystalline Solid with a sweet tarry odor commonly referred to as a "hospital smell" Acetone (also known as propanone, dimethyl ketone, 2-propanone, propan-2-one and β-ketopropane) is a colorless mobile flammable

Production
Commercial production of cumene is carried out through the catalytic alkylation of benzene, with the addition of propylene. Catalysis is the process in which the rate of a Chemical reaction is increased by means of a Chemical substance known as a catalyst Alkylation is the transfer of an Alkyl group from one Molecule to another Benzene, or benzol, is an organic Chemical compound and a known Carcinogen with the molecular formula C 6 H 6 Propene, also known as propylene, is an unsaturated organic compound having the Chemical formula C 3 H 6 Solid phosphoric acid (SPA) supported on alumina can also be used as a catalyst, and this was the case prior to the mid-1990s when zeolite-based catalysts made the other technique commercially redundant. Phosphoric acid, also known as orthophosphoric acid or phosphoric(V acid, is a mineral (inorganic acid having the Chemical formula Zeolites (Greek zein, "to boil" lithos, "a stone" are hydrated Aluminosilicate Minerals and have a micro-porous structure [1]
