About this Book

ULLMANN'S Encyclopedia of Industrial Chemistry

Celebrating the centennial of the first edition in 2014 !


Welcome to ULLMANN'S Encyclopedia of Industrial Chemistry, the benchmark reference in chemistry and chemical and life science engineering.

ULLMANN'S Encyclopedia of Industrial Chemistryis a state-of-the-art reference work detailing the science and technology in all areas of industrial chemistry. Subject areas include: 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 many more.


Fully international in scope and coverage, the contents have been compiled under the supervision of a renowned global Editorial Advisory Board. It 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. With more than 16 million words, nearly 15,000 tables, 25,000 figures, and innumerable literature sources and cross-references, ULLMANN'S Encyclopedia offers a wealth of comprehensive and well-structured information on all facets of industrial chemistry.




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 has 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.Click here to find out more about the 40-Volume Set.

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

Vacuum Technology

Featured article

Christian Day


Vacuum technology produces the vacuum needed to manufacture a product, to support a chemical or physical process, or to allow a technical component to function. Examples are vacuum distillation in the chemical laboratory, freeze-drying in the food industry, semiconductor coatings and thin film preparations, vacuum facilities in large basic-research projects and in everyday technology, such as control by vacuum in an automotive engine or the household vacuum cleaner. Vacuum technology aspects are covered by a series of specific standards, such as the German standards DIN 28400 to 28432, the international standard ISO 3529, and the guidelines of the American Vacuum Society (AVS).

100 Years of Ullmann's: 1914 to 2014

Snapshots from the first Edition

Historical picture from the 1st edition, 1914-1923

Lignite coal tar was an important source of paraffin in Germany which had large and easily accessible deposits of “brown coal”. Paraffin could be crystallized out of the buttery tar fraction at ambient temperatures of -10 °C or less. Once crystallized, the paraffin flakes could be shoveled off and dried, as shown in the picture. Where no active cooling was available, paraffin harvesting had to await the arrival of the winter frosts.
