About this Book

ULLMANN'S Encyclopedia of Industrial Chemistry is the benchmark reference in chemistry and chemical and life science engineering, covering inorganic and organic chemicals, advanced materials, pharmaceuticals, polymers and plastics, metals and alloys, biotechnology and biotechnological products, food chemistry, process engineering and unit operations, analytical methods, environmental protection, and much more.

  • Complete coverage of the science and technology in all areas of industrial chemistry
  • Fully international in scope and coverage, the contents have been compiled under the supervision of a renowned global Editorial Advisory Board
  • New and updated articles are added every two months
  • Contains over 1,000 major articles, written by some 3,000 authors who are experts in their fields and affiliated to leading chemical companies or research institutes
  • Breadth of knowledge - more than 16 million words, nearly 15,000 tables, 25,000 figures, and innumerable literature sources and cross-references
  • All the benefits of an online reference, including: searches using wildcards and Boolean operators and cross-reference hyperlinking

From the reviews:

"The Sixth Edition is the culmination of 90 years experience and tradition, fully international in scope and presentation with articles of the highest quality. It deserves a place in every library that aspires to offer comprehensive reference material on industrial chemistry. I can recommend it without reservation." —Angewandte Chemie  

"In summary, the Encyclopedia is an excellent addition to a technical library. Its broad coverage provides the reader with an excellent source of up-to-date industrial chemistry information, and the reference citations provide an avenue to more detailed information."—Journal of the American Chemical Society  

"Ullmann's is an indispensable gold mine for students, patent attorneys, and researchers [...]. It should be readily available [...] at major public libraries and corporate collections." —Today's Chemist at Work


First published in 1914 by Professor Fritz Ullmann in Berlin, the Enzyklopädie der Technischen Chemie (as the German title read) quickly became the standard reference work in industrial chemistry. Generations of chemists have since relied on ULLMANN'S as their prime reference source. Further German editions followed in 1928 - 1932 and 1951 - 1970. The 25 volumes of the 4th Edition, published in 1972 - 1984, were divided into an alphabetically ordered series of 18 volumes and a general series of six volumes which gave an account of the principles and methods of chemical engineering and process technology. ULLMANN'S Encyclopedia of Industrial Chemistry, 5th Edition, was published from 1985 to 1996. This is the first edition that was published in the English language. ULLMANN'S Encyclopedia of Industrial Chemistry, 6th Edition, was published in December 2002. The 40 volumes including one index volume contained 800 major articles, organized in alphabetical order. Now in its 7th Edition, again in 40 volumes, ULLMANN‘S had over 600 of its articles newly written or substantially updated, in addition to several hundred color figures added throughout. ULLMANN'S 7th Edition is available in print.

Nitrogen Fixation

Dinitrogen, although abundantly available, can only be used in its “fixed” form, like ammonium (NH4) and nitrate (NO3). To become metabolically available, the N≡N triple bond must be broken, and the resulting atomic nitrogen must be chemically bonded with other elements, such as oxygen and/or hydrogen through a process called “nitrogen fixation”. Almost all chemically fixed nitrogen comes from the Haber–Bosch process. Besides using fixed nitrogen as a fertilizer in agriculture, chemically fixed nitrogen in the form of ammonia is also used for large scale applications in chemical industry, e.g., pharmaceuticals, explosives, and plastic manufacturing. The chemical process for nitrogen fixation is notorious for high CO2 emission, energy consumption, and harsh operating conditions. Biological nitrogen fixation, on the other hand, takes place at mild conditions, thus it giving hope for the development of a new artificial nitrogen fixation process operating under mild operating conditions. This possibility has opened doors for different research areas in biological and chemical nitrogen fixation and has been the subject of increasing efforts since 1960s. Various approaches and key concepts involved in biological and chemical nitrogen fixation processes are briefly discussed in this article as well as some commercially applied chemical processes for nitrogen fixation. The figure shown is a schematic representation of the MoFe protein and Fe protein components of nitrogenase.
