The Plan of this Book

The first three chapters of the book are an introduction and review of basic thermodynamics and of very simple equilibrium. Chapters 4—7 set out the basic thermodynamics of equilibrium. Chapters 8-10 deal with the most common type of problem, vapor-liquid equilibrium. Chapter 11 deals with other kinds of phase equilibrium. Chapters 12-13 deal with chemical equilibrium, and Chapters 14,15 and 16 deal with a variety of related topics. Appendix A contains the data tables that are used for examples and homework problems. Appendixes B-G contain derivations and other material that supports the material in main text. It is placed there to keep the treatment in the texi as simple as possible. Appendix H contains answers to some of the problems. 

Equilibrium is one of the four basic tools of the chemical or environmental engineer. It is as important as the others, and is needed for a wide variety of engineering work. 

EquHibriam states are stable, unstable, or neutral. On a molecular level all equilibria are dynamic that is of 

We will work mostly with molar units of mass, and mol fractions as concentration units. 

We will deal with a variety of phase diagrams, of which the vapor-pressure curve is the simplest.

Plan of this book. It will be evident from the foregoing survey of the principal applications of crystallographic methods to chemical problems that these applications fall into two classes firstly, the use of crystal properties for the purpose of identifying substances secondly, the elucidation of the internal structure of crystals by interpretation of their properties. This natural division determines the plan of this book, which is in two main parts, on identification and internal structure respectively. 

I wish to express my appreciation to Messrs. William C. Tanner and Harry S. Katz for their helpful suggestions in the planning of this book. Mr. George Narita, Vice President and Executive Editor of Noyes Publications, has been most helpful in the development of the book. Lastly, I must express appreciation to my wife, Rose-Marie, for her patience and understanding during the many months spent on the book. 

Because it has been possible, following out the plan of this book, to choose specific colloids so typical of the class to which they belong that they suffice to bring out all the important chemical relations involved in colloidal chemistry, the other members have been largely disregarded. The author has made it a fimdamental principle to take up only those colloids the properties of which are known to him through his own investigations. 

In the original planning of this book we were at pains to ensure that the preparations in particular were designed to afford a minimum expenditure of time, materials and heating. We hope that the economy thus introduced will be especially appreciated in view of the recent heavily increased cost of chemicals, fuel and laboratory service. This increased cost, incidentally, must necessarily increase the attraction of the small-scale preparations referred to above. 

For planning purposes, the importanee of subeontraetor partieipa-tion, organization, and planning aetivities is important and should be stressed. Throughout the rest of this book, it is assumed that subeontraetors workers will be eonsidered as part of the work team. 

Years ago, the author and Dr. Amos Banin from the Hebrew University of Jerusalem, Israel started to plan such a timely book to meet the current needs of the world s arid environments. Much research on biogeochemistry of trace elements in arid soils was done by the author and Dr. Banin during the period from 1992 to 1997 when the author was at the Hebrew University. Therefore, a majority of the chapters of this book were formed at that time. Of course, many materials and first-hand data are from the previous publications by the author and Dr. Banin s laboratory. Unfortunately, due to the health problems of Dr. Banin, he was unable to get this project finished. Thus this book is a product that resulted from the collaborative efforts and coauthoring between the author and Dr. Banin. 

I therefore decided to add my own detailed analysis, for whatever it is worth, on the pages of this book. There was so much to add to their responses, I could only take up less than twenty questions here, though I was planning more like fifty. 

Note The remainder of this book presents many ideas that may be useful to share with your client, including suggestions for how the client can choose the right services (in Chapters 3 and 5), how the client can help develop a treatment plan that will serve him or her well in therapy (Chapter 4), steps the client can take to succeed in reaching his or her goals after treatment or therapy, and how the client can move forward into a new life free from drug problems (Chapters 6-8). 

For helping plan the symposium and for handling many of the details involved in the preparation of this book, I would like to acknowledge the assistance and work of my secretary, Mrs. Donna Hahn. 

There has been quite a large stream of research concerned with capacity expansions and retrofit problems in the chemical and operations research literature. In this section, however, we will concentrate on expansion and strategic multisite planning studies. Single site short-term and mid-term planning and scheduling studies are beyond the scope of this book and the interested reader is referred to the work by Bodington and Baker (1990), Pinto, Joly and Moro (2000), and Kallrath (2005). 

Before commencing work in the laboratory, sound planning of the experiment to be undertaken is essential. The detail of such planning, and the level of personal responsibility involved by the laboratory worker, depends on the degree of expertise that has been previously acquired. Three levels of experience may be recognised for the user of this book, although it should be realised that the transition between them is a continuous process. 

The writing of this book was planned and initiated while one author, on sabbatical leave, was a guest in the other s home institution. This was made possible by support from the Japan Society for the Promotion of Sciences, and we are very glad to express our appreciation to the JSPS. We would also like to thank the McDonnell Center for the Space Sciences at Washington University for a variety of kinds of support which greatly facilitated the preparation of this book. 

In summary, all these modifications also imply that compared to the first edition, the size of the second has increased by 50%, just like its price. This aspect gave me the collywobbles because for you this might mean that the price of this book has increased by the equivalent of two visits to an Italian restaurant. But even if this was exactly your plan to crossfinance it shouldn t give you any collywobbles whatsoever, but at best a short-term sense of emptiness in the pit of your stomach. 

In practice, within the framework of this book, this petrochemical process evaluation is limited to the production of second aeration intermediates. Moreover, it does not lead to the identihcation of a single solution, but to the consideration of several different schemes, in as much as each offers a technologically viable answer. It also consists in emphasizing the technical requirements of the conversion operations planned, as well as potential unfeasibiiities related to the inherent facts of the problem this means the need to propose alternative solutions, requiring a minimum of adaptation of the basic data. 

The major portion of most texts on organic chemistry focuses upon reactions that result in the interconversion of functional groups. This huge body of factual material s will not be reviewed here in detail as it is impossible within the volume of this book and unnecessary for our purposes. Our goal is to highlight the importance of these interconversions in a total synthesis. The immense diversity of transformations can be actually reduced to a few types that we hope are sufficient to provide the reader with an understanding of the principles necessary to select the conversions for a chosen synthetic plan. 

Plan your week to include time slots that you are going to set aside for the study of this book. Make them high priority periods, which can only be changed in very exceptional circumstances. 

Shortly after the authors jointly finished the most of the contents of this book and wrote the above text for this preface, Yongdong passed away suddenly at the young age of 43. He still had so much to work for and so much potential to contribute to the field. He was even hoping and planning to revise this text for... 

The initial plan of this book was to concentrate on the histories of the individual companies until 1993, the date of the listings of the top fifty chemical companies as in Table 1.1. Nevertheless, the events of the past few years require an update to the story just told, for Du Pont quietly cast off its major remaining nonchemical activities—namely, oil and pharmaceuticals. So it entered the twenty-first century still as a multisectored enterprise, with the product lines it had commercialized while shaping the Industrial (twentieth) Century before the chemical crisis of the late 1970s and early 1980s. 

Many tools are in the hands of the analyst and management to adapt the laboratory to his task. Figure 1.3 shows that they are of various types. They have to be included in the entire management of the laboratory, e.g. training of staff and motivation must be planned and built in the lifestyle and the lifetime of the laboratory. Quality always pays or as W. Edwards Deming preached cheaper is not always better, better is always cheaper . It may appear to be expensive and time consuming, but it is the only way to cope with unexpected situations, e.g. absence of staff, sudden unexpected workload etc. It is out of the scope of this book to discuss all infrastructure and management aspects necessary to set up a quality system within a laboratory. 

The purpose of this book is to provide a generic format for a Master Validation Plan, also often called a Validation Master Plan (VMP), using a pharmaceutical manufacturing site with both sterile and non-sterile operations as the case facility. The intent is to show basic format and samples of contents for all the sections of the plan, because it provides a road map for validation to establish FDA requirements master validation procedures, validation programmes, execution protocols, and resources planning and scheduling.
