Expanded and corrected.
The only big mistakes were the description of equilibrium, which is inapplicable due to the pure acid being solid, and the statement that sulfur trioxide polymerises on contact with water. I'm unsure of the carbon mass hardening after treatment of glucose with acid, so I'll leave it in. Any comments on this? Ambix 17:53, 15 December 2005 (UTC)
This article about oleum says much about the danger of handling it in, say, a railcar. An incident at the General Chemical plant in 1993 was just the kind of accident that is spoken of in this article; this incident occurred in Richmond, California, USA. Richard8081 21:26, 14 August 2007 (UTC)
Cleaned up some of the extraneous/conversational language throughout the article. No real content changes, just made it more readable. 126.96.36.199 00:46, 22 August 2007 (UTC)
Percent Oleum Calculation
I do not understand how ten percent Oleum would mean H2SO4.0.1SO3. Shouldn't it be x gm of free SO3 for every 100 gm of Oleum?
Too much on the formula and composition in the lead, and nothing on uses, origina of name, etc. Led is supposed to be big picture, not details. LeProf. — Preceding unsigned comment added by 188.8.131.52 (talk) 22:52, 9 January 2013 (UTC)
Use in organic synthesis
I was a bit startled to see that the organic synthesis part of the article mentions the role of oleum in double aromatic nitration, but not in triple nitration. As a matter of fact, oleum, combined with nitric acid, is (among other applications) essential in the third step of production of TNT (Urbanski T (1964). Chemistry and Technology of Explosives 1. Pergamon Press. pp. 389–91. ISBN 0-08-010238-7.) as mentionned in the Wikipedia page of TNT (http://en.wikipedia.org/wiki/Trinitrotoluene#Preparation).
Would this be worth an addition to the article ?
