Hydrolysis of Cumene Hydroperoxide with Dilute H2SO4
Cumene hydroperoxide (CHP) is an organic compound with the chemical formula (CH3)2C(OOH)C6H5. It is a clear, colorless liquid that is commonly used as a precursor in the production of phenol and acetone.
Reaction
The hydrolysis of cumene hydroperoxide with dilute sulfuric acid (H2SO4) results in the formation of phenol and acetone.
Cumene Hydroperoxide + Dilute H2SO4 → Phenol + Acetone
Explanation
The hydrolysis reaction involves the breaking of the O-O bond in cumene hydroperoxide to form a hydroxyl group (-OH) and a carbonyl group (C=O). This reaction is catalyzed by dilute sulfuric acid.
The hydroxyl group (-OH) forms phenol, while the carbonyl group (C=O) forms acetone.
Phenol: Phenol is an aromatic compound that contains a hydroxyl group (-OH) attached to a benzene ring. It is commonly used in the production of plastics, dyes, and pharmaceuticals.
Acetone: Acetone is a colorless, volatile liquid that is commonly used as a solvent. It is also used in the production of various chemicals and as a nail polish remover.
Overall Reaction
The overall reaction of the hydrolysis of cumene hydroperoxide can be represented as:
Cumene Hydroperoxide + Dilute H2SO4 → Phenol + Acetone
