Concept introduction:
Drying agents are used to remove water from organic solvents. Mostly anhydrous drying agents are used that react with water to form insoluble hydrates in organic solvents and can be easily removed by filtration. Parameters that are considered to choose an effective drying agent are as follows:
- Capacity: The maximum number of moles of water molecules that can be trapped by a salt or drying agent defines its capacity.
- Efficiency: The amount of water left behind in the organic solvent after the drying process is called efficiency.
- Speed of removal of water: Time taken by the drying agent to form hydrate determines the speed of removal of water.
- Chemical inertness: Drying agents should be chemically inert that is it should not react with the organic solvent and the organic compounds dissolved in it.
