                 Extensive experiments have been carried out in Germany with fatty acids from the Fischer-Tropsch process with a view to the production of ketones.  The fatty acids were saponified with lime and the resulting calcium salt subjected to dry distillation.  A mixture of ketones of great variety was obtained.  Experiments were carried out with fractionated fatty acids, and these showed that the ketones obtained corresponded closely in boiling and solidification range to the theoretical figures.  Various types of ketones were obtained.  Some were liquids with a pleasant odor, others were white solids of waxlike appearance.  They can be used in the cosmetics industry or as plasticizers.
