When accurate quantities of liquid reagents are required, the best technique is to deliver the desired amount of liquid reagent from the pipette into a container whose tare weight has been determined previously. The container, with sample, is then weighed a second time in order to obtain a precise value of the amount of reagent. Automatic pipettes may vary in design, according to the manufacturer. The following description, however, should apply to most models. The automatic pipette consists of a handle that contains a spring-loaded plunger and a micrometer dial.
4 Setting the temperature of the hot plate too high will result in too much loss of solvent through evaporation. C A U TION In performing the following procedure, keep in mind that the mixture in the Craig tube may erupt out of the tube if it becomes superheated. You can prevent this by stirring the mixture constantly with the spatula and by avoiding overheating the mixture. Dissolving the Sulfanilamide Before heating the Craig tube containing the sulfanilamide, add enough hot solvent with a Pasteur pipette to barely cover the crystals.
6 Your goal will be to find a good solvent for crystallizing the sample. You should try water, methyl alcohol, and toluene. After you have determined which is the best solvent, crystallize the remaining material. Finally, determine the melting point of the purified compound and of the impure sample. 6 with three separate samples of impure fluorene. Use the following solvents: methyl alcohol, water, and toluene. 5 An alternative method for inducing crystallization is to dip a microspatula into the solution.
