Notebook technique experiment

Assemble a distillation apparatus using your smallest round-bottom flask to distill from (Technique 14, Figure 14.10, but insert a water condenser as shown in Experiment 7A). Use a hot plate with an aluminum block to heat. Preweigh (tare) and use a 5-mL conical vial to collect the product. Immerse the collection vial in a beaker of ice to ensure condensation and to reduce odors. Distill your ester and record its boiling-point range in your notebook. 

This textbook is divided into two major sections (see Table of Contents). The first section, which includes Part One through Part Five, contains all of the experiments in this book. The second major section includes only Part Six, which contains all of the important techniques you will use in performing the experiments in this book. Interspersed among the experiments in Part One through Part Three is a series of essays. The essays provide a context for many of the experiments and often relate the experiment to real world applications. When your instructor assigns an experiment, he or she will often assign an essay and/or several techniques chapters along with the experiment. Before you come to lab, you should read all of these. In addition, it is likely that you will need to prepare some sections in your laboratory notebook (see Technique 2) before you come to the lab. 

At some point in the near future you should watch the video entitled Thin-layer chromatography in use an application from the food industry in the multimedia activity Practical techniques on the Experimental techniques CD-ROM that accompanies this book. There you will see an experiment on the separation of food colourings. At various times you will be asked to take notes or make measurements from the screen, so you should make sure that you have an experiment notebook and pen to hand. This activity should take about...
