Contact process of manufacturing of sulfuric acid in the industries.

What is H2S2O7?

It is pyrosulphuric acid or oleum. —vedant (talkcontribs) 19:04, 19 March 2006 (UTC)
it is oleum Elncid (talk) 11:58, 11 June 2008 (UTC)


Every textbook I've ever read has referred to the Contact Process as just the reversible reaction producing sulphur trioxide from sulphur dioxide and oxygen, not the entire process of the production of sulphur. I know article kind of gets this across, but the first line, "The contact process is the current method of producing sulphuric acid in the high concentrations needed for industrial processes" is misleading. Perhaps a re-write is in order here. Liverpool Scouse 11:31, 9 December 2006 (UTC)

IUPAC spelling[edit]

The standard for spelling of sulfur in science article is sulfur.

In the interest of consistency and clarity the IUPAC standard should be used for chemical names in all science articles. Alternative spellings should be referenced in addition, especially when dealing with regional issues and historical development.
  • The IUPAC currently recommends:
  • Aluminium instead of aluminum
  • Caesium instead of cesium
  • Sulfur instead of sulphur

A correction[edit]

Hey, I was never good at chem, but every textbook I have read says that a catalyst does not change the position of equilibrium. But the article says "A catalyst is necessary for this reaction or the equilibrium of the reaction would move to the left, producing more SO2." I think this is wrong, but just to make sure, I am posting this in discussions. —The preceding unsigned comment was added by (talk) 16:49, 7 April 2007 (UTC).


I've added a {{contradict}} tag because the article can't seem to decide if Vanadium or Platinum is used as the catalyst, and which is poisoned by impurities. MrBell (talk) 17:40, 18 January 2010 (UTC)

Catalytic cycle - Vanadium oxidation state[edit]

The following publication shows that vanadium does not undergo a change in oxidation state in this process. The German Wikipedia shows the graphic to the catalytic cycle as found by Lapina et al. Could anyone please correct it?

O.B. Lapina, B.S. Bal'zhinimaev, S. Boghosian, K.M. Eriksen, R. Fehrmann: Progress on the mechanistic understanding of SO2 oxidation catalysts, in: Catalysis Today, 1999, 51, pp 469–479 — Preceding unsigned comment added by (talk) 19:05, 1 February 2013 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Contact process. Please take a moment to review my edit. You may add {{cbignore}} after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether, but should be used as a last resort. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Question? Archived sources still need to be checked
