Legality: DEA Listed Chemicals
Production of this substance may be illegal in some jurisdictions under certain circumstances.
21CFR1310.02 a & b
In 1995/6, two lists were created "List I" and "List II", for which commercial manufacturers and distributors must register, and for which possession with the intent to manufacture illegal substances (such as methamphetamine, ecstasy, etc) is illegal. On these a few dozen "precursor" compounds commonly used in the manufacture of illegal drugs. [1] [2]
Bottom line: Do not produce this chemical without checking to make sure that you may do so legally.

Propanone is the simplest example of a ketone.
Uses
- Early C3 compound
- Fuel
- Solvent
- Liquid/liquid extraction solvent (particularly for plant alkaloids)
- Feedstock for:
- trichloromethane
- trimethyl benzene
- ethenone
- isopropanol (hydrogenation w/Urushibara nickel)
Production
Bioproduction
See Fermentation (ABE).
Synthesis
Generally, (di)acetates can be dry-distilled into propanone and a carbonate
- Dry distill 160g calcium acetate crystals at about 160°C, leaving 100g of calcium carbonate, and 60g propanone.
- Ca(CH3COO)2 → CaCO3(s) + CO(CH3)2(v)
- Dry distill lead (II) acetate leaving lead (II) carbonate and propanone
- Ca(CH3COO)2 → CaCO3(s) + CO(CH3)2(v)
