What happens when cumene hydroperoxide?
When cumene hydroperoxide is treated with dilute sulphuric acid, it gives phenol and acetone.
What is the formula of cumene hydroperoxide?
C9H12O2Cumene hydroperoxide / Formula
What is the boiling point of cumene?
306.3°F (152.4°C)Cumene / Boiling point
What is the difference between phenol & alcohol?
Moreover, in phenols, the hydroxyl group is directly bonded to the aromatic ring and not the carbon atom….
| Difference Between Alcohol and Phenol | |
|---|---|
| Alcohols show no impact or reaction during tests as they are mostly neutral. | Phenol can change litmus paper red as they are acidic in nature. |
How is cumene converted to phenol?
Complete step by step solution: On oxidation of cumene (Isopropyl benzene) in the presence of air, cumene hydroperoxide is found. Upon further action of cumene hydroperoxide with dilute acid, phenols are produced. Acetone is also made as one of the by-products of the reaction in large quantities.
How is cumene converted into phenol?
Cumene (isopropylbenzene) is oxidised in the presence of air to cumene hydroperoxide. It is converted to phenol and acetone by treating it with dilute acid. Cumene is oxidised into cumene hydro peroxide by air at high pressure which on decomposition by aqueous acid gives phenol and acetone.
What is the Iupac name of cumene?

What is cumene formula?
C9H12Cumene / Formula
Which is stronger acid alcohol or phenol?
Phenols are stronger acids than alcohols, but they are still quite weak acids. A typical alcohol has a pKa of 16–17. In contrast, phenol is 10 million times more acidic: its pKa is 10. Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion.
What are the chemical properties of cumene hydroperoxide?
CUMENE HYDROPEROXIDE is a strong oxidizing agent. May react explosively upon contact with reducing reagents. Violent reaction occurs upon contact with copper, copper alloys, lead alloys, and mineral acids. Contact with charcoal powder gives a strong exothermic reaction. Decomposes explosively with sodium iodide [Chem. Eng. News, 1990, 68 (6), 2].
How do you make hydroperoxide from cumene?
Cumene hydroperoxide is obtained by oxidizing cumene with air, usually in a cascade of stirred-tank reactors or bubble columns at temperatures in the range of 100-140 deg C and a pressure of 6-7 bar and usually with small amounts of a buffer to prevent acids from building up.
What is the chemical name of cumene?
Cumene is an alkylbenzene that is benzene carrying an isopropyl group. Cumene is used in a variety of petroleum products. Acute (short-term) inhalation exposure to cumene may cause headaches, dizziness, drowsiness, slight incoordination, and unconsciousness in humans.
What are the side effects of cumene in humans?
Acute (short-term) inhalation exposure to cumene may cause headaches, dizziness, drowsiness, slight incoordination, and unconsciousness in humans. Cumene has a potent central nervous system (CNS) depressant action characterized by a slow induction period and long duration of narcotic effects in animals. Cumene is a skin and eye irritant.
