[edit] Information Sources

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Chlorine. Additional text was taken directly from, USGS Periodic Table - Chlorine, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the main page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

[edit] Gas image

I noted the comment "gas, doesn't look like much" with the picture provided. The best pictures I've seen of chlorine are from leaking railroad cars. See http://www.hazmat101.com/, click on the 'files' link in the colored bar at the top and look at the power point file in the November 2003 section titled "Rail tank car chlorine leak photos". The last slide is especially good - the yellow-green color is particularly good. Also note the gas hanging to the ground and not pluming into the air.swc 21:30, 4 October 2005 (UTC)

[edit] Chlorine-36

The Cl-36 (³⁶Cl) info at [1] has several differences from that in [2]. (SEWilco 07:18, 12 May 2005 (UTC))

Subsurface production by muon capture of 40-Ca? Where do the muons come from in such scenario? --Shaddack 18:44, 23 November 2005 (UTC)

[edit] Chlorine + Alcohol = Explosion?

Is this true? --Arima 02:03, 25 November 2005 (UTC)

Well, chlorine is a powerful oxidizing agent, and alcohol burns in an oxygen atmosphere, so I see no reason why it wouldn't burn in a chlorine atmosphere. I suppose you'd get alcohol to explode in chlorine the same way you'd get it to explode in oxygen: mix alcohol vapor or aerosolized alcohol with pure chlorine gas, then provide an ignition source. The required temperature might be low enough for spontaneous ignition at room temperature, but I don't know. --Carnildo 19:14, 25 November 2005 (UTC)

• You might be referring to that (in)famous video [3] where some young idiots have a plastic bottle in which they "add the chlorine to the alcohol" and "shake it up hella good" (and nearly kill themselves with the resulting explosion, it looks like). However, what they're probably using is the kind of so-called "chlorine" used in pools as disinfectant, which is actually sodium hypochlorite. And it does seem to explode pretty well. --Bob Mellish 19:38, 25 November 2005 (UTC)

• (Note: 206.131.130.132 (talk • contribs) edited my comment above to change sodium hyprochlorite to calcium hypochlorite, with the comment "Re-Corrected by SINYpyro."

1. Please don't change other people's comments on talk pages.
2. There are a number of bleach-type compounds commonly but incorrectly called "chlorine", including both calcium and sodium hypochlorite. --Bob Mellish 17:13, 13 March 2006 (UTC)

• I'ts sad how many people there are out there who change what people have written. I feel for you. --Ruff 04:06, 28 July 2006 (UTC)

• From the video, it appears to be some sort of pressure explosion, not combustion. Anyone know what the reaction/gas produced is?

• I have a feeling that it is hydrazine, but I'm not in the least sure. Ruff ^{Bark away!} 20:59, 25 August 2006 (UTC)

• Hydrazine is definately believable, a friend and I have been messing around with chlorine/alcohol quite a bit lately, and the resulting gas is highly flammable (like rocket fuel =]) I can also verify that it causes an explosion, but only because of the release of the gas, and I think it's a similar reaction to the chlorine/ammonia one that produces hydrazine.

[edit] Looks like references are the order of the day here?

It seems to me the first task for the collaboration is references. I can see about asking my Chemistry teacher if he knows any good, you know, chemistry books that'll have a bunch of detail on Chlorine, because they'll probably just repeat what's already in this article yet it'll certainly go a long way. However, thinking about Chlorine, could not the more social aspects of chlorine be emphasized, you know, maybe a picture of a pool with chlorine used to keep it clean, more detail on how chlorine was sometimes used in gas form as a weapon of war in WW1 if I remember correctly, etc. etc., all that stuff kind of is notable for Chlorine after all.

I added some information about chlorine and WWI from the Use of poison gas in World War I article. It has an OK amount of info but there is still a long way to go. As a suggestion I think we should model it after some of these articles: Acetic acid Helium, Hydrochloric acid, Technetium. Tarret 00:31, 2 May 2006 (UTC)

[edit] Safety (a.o.)

This is an article about an important element, chlorine. It has been rated A-class. But it has accumulated much information which is anecdotal (mainly concerning safety, but also about external organizations/suppliers). As was done with aniline, hydrazine and hydrogen sulfide, much of that infomation has been removed, or compacted into one or two sentences. For more safety data one can consult an MSDS sheet. --Dirk Beetstra ^{T C} 22:15, 13 August 2006 (UTC)
