For macroscale crystallizations, extractions, and quick cleaning of apparatus, it is convenient to have a bottle of each frequently used solvent—95% ethanol, ligroin or hexanes, dichloromethane, ether, and ethyl acetate. A pinhole opposite the spout, which is covered with the finger when in use, will prevent the spout from dribbling the solvent. For microscale work, these solvents are best dispensed from 25-mL or 50-mL bottles with an attached test tube containing a graduated (1-mL) polypropylene pipette (Fig.

Begin each experiment on a new page. Include an outline of the procedure and the method of purification of the product in a flow sheet if this is the best way to organize the experiment (for example, an extraction; see Chapter 8). The flow sheet should list all possible products, by-products, unused reagents, solvents, and so on that are expected to appear in the crude reaction mixture. , by extraction, various washing procedures, distillation, or crystallization). With this information entered in your notebook before coming to the laboratory, you will be ready to carry out the experiments with the utmost efficiency.
