What is cohobation in pharmacy?
Ali Talati, Biotechnologist (Aromatic and Medicinal Plants Pharmacy) Cohobation is a procedure that can only be used during water distillation or water and steam distillation. It uses the practice of returning the distillate water to the still after the oil has been separated from it so that it can be re-boiled.
What is meant by cohobation?
to distill again from the same or a similar substance, as by pouring a distilled liquid back upon the matter remaining in the vessel, or upon another mass of similar matter.
What are the types of distillation?
Types of Distillation
- Simple Distillation. It involves the immediate change of liquid state to vapours state and condensing of vapours by cooling.
- Fractional Distillation.
- Steam Distillation.
- Vacuum Distillation.
- Zone Distillation.
- Air- sensitive vacuum Distillation.
- Short–path Distillation.
- Other types.
Why is distillation used?
Distillation is used to separate liquids from nonvolatile solids, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil.
How whiskey is distilled?
How Whiskey Is Made
- Combine the base ingredients. To make a fermentable base, whiskey makers will mix grains—like wheat malt, flaked maize, or rye—with water and yeast.
- Ferment the base.
- Strain the mixture.
- Distill.
- Collect and sort the distillate.
- Age the liquor.
- Dilute.
- Bottle.
What is known as distillation?
Distillation is a process where a mixture made of two or more liquids (called “components”) with different boiling points can be separated from each other. The mixture is heated until one of the components boils (turns to a vapor). Distillation is a commonly used operation in many industries.

What is cohabitation and how does it work?
Cohabitation is when two people who are romantically involved choose to live together without making the formal commitment of marriage.
What is the process of cohobation in chemistry?
Cohobation has no corresponding process in modern chemistry, as it is not a useful process. Indeed, it is equivalent to performing the same distillation a number of times and does not increase the purity of the distillate or alter the residue any more than would be done by maintaining it at elevated temperature for the same period of time.
What is the difference between cohobation and circulation?
Cohobation is a kind of circulation, only differing from it in this, that the liquid is drawn off in cohobation, as in common distillation, and thrown back again; whereas in circulation, it rises and falls in the same vessel, without ever being drawn out. Cohobation has no corresponding process in modern chemistry, as it is not a useful process.
