acidified and redistilled if desired. This can be avoided by employing dry distillation, i.e., distillation without using steam or any gaseous medium as carrier of the fatty acids. Such process was developed by Mills (1942) who employed a combination of dry and flash distillation to recover fatty acids from hydrolyzed fats and oils (Fig. 3).

How is steam distillation different from simple distillation?

Apr 02, 2020 The advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds.
