[edit] The Band
I noticed the following was added to this article. It really is not relevent to the subject matter presented.
Naphtha is also a band from Kennesaw, Georgia. They play local shows and are working on getting signed
I would suggest creating a separate article. Grundle 15:02, 19 May 2006 (UTC)
[edit] naptha
isn't the title spelt wrong? should be naptha, not naphtha.
ah sorry, it is naphtha.. woops

[edit] Air Sampling for Naphtha Section
Something is crazy about the way the code for this section is rendered. If you look at the references, you see that some of the material from the article has been translated into references. Much of the material, particularly in the "Active Air Sampling Method..." section is not visible in the article at all, even though it is in the code.
If you try to edit parts of the Air Sampling section, you are shown parts of the article toward the front.
The DiNardi reference is wierdified.
I have been trying to straighten this out for several hours, and I am stumped.
- I've removed the Air Sampling section for the time being. It was obviously a cut & paste from an OSHA-type technical document, and is WAY too specialized, technical and long for an encyclopedic article. None of the information contained therein would be useful or intelligible to the average reader. The content would be better placed in an article about air sampling. If someone feels a mention must stay in this article, then at least greatly condense it. One arguably unimportant subsection should not constitute over 90% of the article's content.
- In short, the technical nature, and sheer length of that section greatly detracts from the article's readability and overall quality, and it needed to go. 97.82.247.200 00:28, 11 September 2007 (UTC)
[edit] cleanup
There is some useful information in here, but the readability is nil in this state:
white spirit (though in the UK white spirit is something completely different), Ligroin; VM&P Naphtha (CAS No. 64742-89-8); Varnish Makers and Painter's Naphtha [1]; Benzin; Petroleum Naphtha, Naphtha ASTM, Petroleum Spirits, Shellite, Ronsonol, Energine; not to be confused with Naphthalene) is a group of various liquid hydrocarbon intermediate refined products of varying boiling point ranges from 20 to 75 °C (68 to 167 °F), which may be derived from oil or from coal tar, and perhaps other primary sources.
I've removed to here until either I have a chance to re-write or someone else does. - IstvanWolf (talk) 21:32, 9 January 2008 (UTC)
[edit] molecular weight, specific gravity and boiling point ranges
The molecular weight, specific gravity and boiling point ranges are suspect, as is the indicated vapor pressure. While not overly familiar with any aromatic naptha mixtures, at least some, lighter, so-called parafinic napthas or petroleum ethers (mixtures similar to hexanes) will have boiling points below 100°C (212°F) and densities < 0.7 g/ml. Also n-pentane and n-hexane have 72 and 86 mol wts respectively. A specific reference might benefit this section.
