Ullmann's Encyclopedia of Industrial Chemistry

The first edition was published in German by Fritz Ullmann in 1914. The 4th Edition, published 1972 to 1984, already contained 25 volumes. The fifth edition, published 1985 to 1996, was the first version available also in English. In 1997, the first online version was available, which is updated at least every other month. As of 2016, Ullmann's Encyclopedia is in its 7th edition, in 40 volumes including one index volume.[1]

While PDF versions of individual chapters used to be available for purchase from the Wiley Online Library, as of at least 9/2018, it appears that Wiley has restricted access to the online version only to institutional users.[2] Therefore, it is no longer possible to purchase individual chapters through the Wiley Online Library. For individuals or small companies, the only option is to purchase the entire hardcopy 40-volume set.

Industrial chemistry is the study of chemistry with a higher mathematics and physics education for critical processes engineering and maintenance. The industrial chemist strengthens the association of new materials investigation and manufacturing development, amid research chemistry and chemical engineering, through innovative intelligence and quality management.

Subject areas include "inorganic and organic chemicals, pharmaceuticals, polymers and plastics, metals and alloys, biotechnology and biotechnological products, food chemistry, process engineering and unit operations, analytical methods, environmental protection and others".[1]

As of 2016, Barbara Elvers is Editor-in-Chief and the editorial board consists of 17 editors, all but 3 of them from Germany.[3]
