Historically, the biggest production of oleum came from the distillation of iron sulfates at Nordhausen, from which the historical name Nordhausen sulfuric acid is derived.

Because of that, sulfuric acid is sometimes concentrated to oleum for in-plant pipelines and then diluted back to acid for use in industrial reactions.

But emergency crews early Friday evening were still trying to contain an oleum leak from a storage tank next to the exploded rail car, BASF officials said.

Rancho El Pinole extended over land that today includes most of the Franklin Ridge, Hercules, Martinez, Oleum, Pinole, Rodeo, Selby and Tormey.

The name, coined in 1863 by linoleum's inventor, Frederick Walton, comes from the Latin words linum ( flax ) and oleum ( oil ).

This has now mostly been replaced by the less expensive procedure that uses a nearly 1 : 1 solution of oleum and azeotropic nitric acid ( 70 % ).
47.
An edition of the book was dedicated to Chichib�bin's daughter, Natacha, who was killed by an oleum explosion in a chemical production factory in 1930.

:"'Safety "': remember, concentrated H 2 SO 4 and oleum are also strong oxidizers and can violently react with many chemicals.
49.
The polyhalogen cations are strong oxidizing agents, as indicated by the fact that they can only be prepared in oxidative liquids as a solvent, such as oleum.
50.
In addition to being a far more economical process for producing concentrated sulfuric acid than the previous lead chamber process, the contact process also produces sulfur trioxide and oleum.
