Contents
Properties
Chemical
Benzylacetone can be reduced to 4-phenyl-2-butanol, reaction which yields both stereoisomers. Aluminium isopropoxide an be used as reducing agent.
Like with all methyl ketone compounds, addition of a basic solution containing iodine will yield iodoform.
Physical
Benzylacetone is a colorless liquid, with older samples having a yellowish tint, presenting a strong floral-like odor. It is immiscible with water, but miscible with most organic solvents. Its taste has been described as "strawberry".[1]
Availability
Can be bought from chemical suppliers.
Preparation
Can be prepared by the hydrogenation of benzylideneacetone.
Alternatively, it can be obtained from the reaction of acetic anhydride and phenylpropanoic acid.
Projects
- Make 4-phenyl-2-butanol
- Make perfumes and odorants
- Attractant for melon flies
Handling
Safety
Benzylacetone doesn't appear to be harmful, but it may be irritant.
Storage
In closer, airtight bottles, away from light and air.
