Industrial products that are made from, or contain, nitrogen are described in parts of some encyclopedias and standard reference works. However it is not always simple to determine from these varied sources the present status of the technology and markets for various nitrogen products. We therefore perceived a need for a text that provides a comprehensive description of: 1) products that are made from or that contain nitrogen; 2) the processes that produce these products; and 3) the markets that consume these products. I have attempted to present the material in a standardized format that should make this book easy to use and helpful to the readers. The standard format for each product is: Introduction, Process, Production, and Uses, with some variations in different chapters. This book provides information that could be used by a wide range of readers: Fertilizer companies—to evaluate different production processes and review general trends in the market. Basic chemical companies—to evaluate different production processes and review general trends in the market. Specialty chemical companies—to investigate new chemical production and/or sales opportunities and the processes that could make those sales a possibility. Chemical distributors—to obtain a feel for the general market size for some chemicals and the basic handling and distribution procedures for various chemicals. Engineering Companies—to evaluate different production processes and review general trends in the market. Engineering and Chemistry Students—to learn more about practical applications of the principals that they have experienced in their classrooms and laboratories.
