Name the Technique

Question 1

A procedure for purifying compounds.
The most typical situation is the desired compound is contaminated by a small amount of impurities.
The mixture is dissolved in the smallest amount of solvent and warmed.
The solution is allowed to cool and the solid formed is separated by filtration.

Answer 1

Question 3

A procedure for purifying compounds.
The most typical situation is the desired compound is contaminated by a small amount of impurities.
The mixture is dissolved in a organic solvent and partitioned with water.
The organic layer is removed, dried and evaporated to yield the organic substrate.

Question 4

A procedure for purifying compounds.
The most typical situation is the desired compound is contaminated by a small
amount of impurities.
The mixture is dissolved in a organic solvent and partitioned between a solid polar matrix and organic solvent system.
The organic solvent is collected, monitored for purity and evaporated to yield the organic substrate.
