Has anyone read anything about the effects of xylene on tissue sections, and DNA? Tristanb 05:24, 16 Aug 2003 (UTC)

Does anyone know the history and discovery of xylene? How it came about? When? Where? Etc?

Explanation of the SP2 and sp3 hybridization unnessessary in this context.

There are several mistakes in this article -- the bond angles (109.5), the alternation of single-double bonds, the uniqueness of benzene as the only aromatic compound w/ 6 carbons in the main ring. ---

It looks like a good deal of this page was taken directly from http://www.atsdr.cdc.gov/tfacts71.html. Sorry I don't have time to fix this. --Noii 20:15, 14 July 2005 (UTC)

Needed citations in Health
I think the needed citations can be found on http://www.temarry.com/chemicals/xylene.htm —Preceding unsigned comment added by 88.197.168.201 (talk) 19:01, 11 August 2008 (UTC)

I don't have the expertise to rewrite the health section but the casual reader could easily be mislead into believing that xylene is reasonably safe. Products I have used that contain xylene recommend wearing protective gloves and breathing masks with absorbents. Also try googling 'xylene msds' and reading the procedures for dealing with poisoning. Hedley — Preceding unsigned comment added by Hfinger (talk • contribs) 01:10, 12 January 2012 (UTC)
 * Xylene is reasonably safe stuff if you know what you are doing. The following comments apply to acute toxicity: the LD50 for rats is 4300 mg/kg, which means that a 100 kg rat (kinda like me) would need to eat half a liter to get to the 50% lethality level.   You are welcome to wear masks and gloves .. we expect our techs to do the same, but a knowledgeable chemist can handle it safely on the bench in beakers or in 5 gal buckets in open air (so long as they can resist the temptation to drink very much of the stuff).  BTW, when you get around to using sodium chloride, here's a tip from that MSDS: "Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product."  Enjoy your chemistry, --Smokefoot (talk) 02:34, 12 January 2012 (UTC)

It's nice that xylene isn't acutely toxic, but most people probably don't want to deal with the health effects of prolonged exposure. There's a reason the OSHA permissible exposure limit is 100 ppm. Here's a paper I found with a quick google search: http://www.ncbi.nlm.nih.gov/pubmed/3822254 — Preceding unsigned comment added by 97.65.97.142 (talk) 22:35, 2 April 2013 (UTC)

error in health effects?
Right now Health Effects reads in part "High levels from exposure for short periods (14 days or less) or long periods (more than 1 year) can cause headaches..."

Does that mean that the headaches go away after 2 weeks only to return after a year?

Irrelevant?
Does anyone else feel that the Background section of Structure isn't really necessary? Perhaps some links to relevant articles instead? --Trlblzr 04:51, 3 November 2005 (UTC)

I totally agree, it seems pointless in this article. --cb2292 12:15, 29 June 2006 (EST)

the edit which i have added, it is not a test, or  a joke —Preceding unsigned comment added by Honeybun (talk • contribs) 14:38, 14 December 2005


 * As important as it may be to you, it's really not relevant information for an encyclopedia article. Edgar181 16:22, 14 December 2005 (UTC)

Xylene as fixative
Please amend "Xylene is also used as a fixation agent for animal tissues" as this statement is quite incorrect. Water soluble substances such as Formal saline (usually) or Zenkers or Bouins fixatives are used to "fix" the material (denature protein, stiffen the specimen and destroy microorganisms). The fixed material is dehydrated in alcohol, then cleared with xylene (the xylene defats the tissue and makes is permeable to the paraffin wax in which is is embedded for sectioning). For a paper citation, any standard histotechnique text such as Bancroft and Gamble should suffice —Preceding unsigned comment added by Marek1975 (talk • contribs) 14:57, 24 October 2008 (UTC)

xylene as a gasoline additive?
when gas was expensive, everyone was looking for quick fixes and alternatives, well....they're apparantly still out there, from magic pills, to magnets, and then Acetone(2 oz. per 10 gallons)....well, I found a video online (Hey now, I read it on the internet, it must be true? lol) which mentions this Xylene, in addition to Acetone...following is the video. --67.34.188.252 (talk) 03:49, 23 December 2008 (UTC)

The boiling point is actually a physical property
Under the heading chemical properties, it is said that the chemical properties of the three xylenes is slightly different. However, boiling point is a physical property. —Preceding unsigned comment added by Fabiennegoosens (talk • contribs) 17:49, 14 June 2009 (UTC)

Formatting
The table for all compounds that usually appears on the right side, is placed in the centre making it look very ugly. I am not very good at this type of formatting. If someone could please re-align the table perfectly. Darshit 23:59, 5 April 2010 (UTC) —Preceding unsigned comment added by Darnir redhat (talk • contribs)

Proposed merger from Xylyl
Naphthyl redirects to Naphthylene, Benzyl to Benzene, Indolyl to Indole, and Thienyl to Thiophene. That, in addition to the lack of novel content available on the Xylyl page, leads me to believe that these should be merged. Enix150 (talk) 02:41, 1 November 2012 (UTC)

Minimum Melting Mixture
Of course, the three isomers have one. Would someone please report in this article, the composition and melting point of same, and also same for the pair-wise mixtures. C.s.auaeginal (talk) 01:56, 9 January 2013 (UTC)c.s.auaeginal

Safety>Handling
In the handling section, it says use of gloves is recommended. However, I noticed today Xylene seemed to dissolve my latex gloves.

If anybody know of other materials that are resistant, please include it in the safety section.
