Preface to the d Second E ition
It is heartening to hear of your book being read and enjoyed, literally cover to cover, by individuals ranging from talented high-school science students to Professors Emeritus of the English language. Even better to hear that you have a chanceto improve that book, based upon the above comments, comments by reviewers, and the experience gained from working with the text. In this edition of The Organic Chem Lab Survival Manual, the section on notebooks and handbooks have been expanded to include typical notebook pages and actual handbook entries along with interpretation. There are new notes on cleaning and drying glassware, and how tofind a good recrystallization solvent. Once their samples are purified, students may now find directions for taking a melting point with the Thomas-Hoover apparatus. Washing has been given the same importance as extraction, and a few more trouble spots -taking the pH of an organic layer, for one -have been smoothed. There are additional instructions on steam distillation using external sources ofsteam. Simple manometers, coping with air leaks, and the correct use of a pressure- temperature nomograph enhance the section on vacuum distillation. Refractometry has been added, as well as-by special requestsections on the theory of extraction and distillation, including azeotropes and azeotropic distillation, and, I believe, the first application of the ClausiusClapyron equation as a bridge forgetting from Raoult's Law (pressure and mole fraction) to the phase diagram (temperature and mole fraction). Many people deserve credit for their assistance in producing this edition: my students, for helping me uncover what was lacking in the previous edition, with Mr. Ronald Pohadsky and Mr. Barry Eggleston making specific suggestions while working in the laboratory. A special thanks toProfessor G.J. Janz, director of the Molten Salts Data Center at the Rensselaer Polytechnic Institute for his review of the physical chemistry sections of this edition, and to Professors Henry Hollinger and A. Rauf Imam for their help during the initial phases of that work. I would also like to thank William Epstein University of Utah Rudolph Goetz Michigan State University


Clelia W. Mallory University of Pennsylvania J. Wolinsky Purdue University for their valuable comments and suggestions in making this edition more useful for students of organic chemistry laboratory. Finally, I'd like to thank Mr. Dennis Sawicki, Chemistry Editor at John Wiley & Sons, first, for one of the nicest birthday presents I've gotten in a while, and second, for his encouragement,guidance, and patience at some troubling points in the preparation of this edition. Ms. Dawn Reitz, Production Supervisor, Ms. Ann Meader, Supervising Copy Editor, and Mr. Glenn Petry, Copy Editor deserve a great deal of credit in bringing this second edition about. J. W.
