General Rules:

1. Halogenated solvents possess a higher density than non-halogenated solvents.

2. Halogenated solvents are not flammable.

3. Ethers like tetrahydrofuran and diethyl ether tend to form (explosive) peroxides. Careful!

4. Low boiling solvents e.g. diethyl ether, dichloromethane, etc can build up a significant pressure when used in extractions. Make sure that the solutions that you are using are at room temperature or below.
