Methods of Production

Propanone is produced through several industrial processes, primarily from the oxidation of isopropanol and from by-products of other chemical syntheses. Additionally, paying attention to acetone density g ml.

1. Cumene Process (Indirect Method)

While primarily used for phenol and acetone production, the cumene process involves:

Step 1: Oxidation of cumene to cumene hydroperoxide

Step 2: Acid-catalyzed cleavage of cumene hydroperoxide to phenol and propanone

This method is prevalent in large-scale factories due to its efficiency and high yield.

2. Direct Oxidation of Isopropanol

A simpler and more direct method involves:

Catalytic oxidation: Using oxidizing agents like potassium dichromate or chromic acid in the presence of sulfuric acid

Reaction: Isopropanol (C₃H₇OH) is oxidized to propanone (acetone) and water

3. Fermentation and Biological Methods

Though less common industrially, some biotechnological processes involve microbial fermentation of carbohydrates to produce acetone, historically significant during the early 20th century.
