DeanStarklaitteella
Dean-Starklaitteella, or the Dean–Stark method, is a laboratory distillation technique used to determine the water content of a sample by azeotropic distillation with an immiscible organic solvent. It is widely applied in industries such as fats and oils, polymers, and resins to assess moisture or extractable water in materials that contain solids or oils.
The principle relies on heating a sample with an appropriate solvent that forms an azeotrope with water
Typical procedure involves weighing a known amount of sample into the flask, adding solvent, and assembling
Advantages of the method include direct measurement of moisture in samples with solids or oils and the
