Chemicals Discussion[edit]

The discussion here concerns all parts of the Chemicals WikiProject, including the infoboxes, lists, standards, includes/excludes, tools, contributors, etc etc etc. Feel free to add your comments to any section here, or start a new topic. Topics not specifically related to the Chemicals WikiProject would be better served at other wikipages.

Actual wikiproject info: statistics and alerts[edit]

The worklist shows the actual work to be done to achieve the goals of the Chemicals wikiproject. The choice of important compounds articles to work on has been finalized in an earlier stage of the wikiproject (around mid 2005), and no further articles are added, although we remain open for strong suggestions on this talkpage. The work these days focuses on improving the articles, from Chem Stub all the way to Chem A-Class articles. The table below shows that progress.

The percentage ≥ Chem Start was indicative of the initial effort. Now that we are progressing to more advanced progress, the weighted progress indicator is used, calculated as (Unclass*0 + Stub*1 + Start*2 + B-Class*3 + A-Class*4) / (Articles*4).

Fluorine peer review[edit]

Please review and fix "Fluorine". In particular, I know there are some top notch practicing chemists here. What I want is a check of the science, especially the structural compound review at the end for mistakes in fact or emphasis. Thanks.-TCO

Comment on the WikiProject X proposal[edit]

Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)

GHS pictograms will be deleted January 1. 2015[edit]

I just saw on commons that the GHS pictograms (GHS-pictogram-acid.svg, GHS-pictogram-bottle.svg, etc.) will be deleted January 1. 2015. We are using them a lot. Maybe the license can be changed to {{PD-ineligible}}...? Christian75 (talk) 16:59, 18 November 2014 (UTC)

Neither of those two files appears to be tagged for deletion. Got a link to where this thing was you saw on commons? DMacks (talk) 17:37, 19 November 2014 (UTC)
GHS symbols are intended to be used internationally as universal warning signs. The UN normally waves copyright when it makes things like this, so I can't imagine why they would be up for the chop. Project Osprey (talk) 17:50, 19 November 2014 (UTC)
User:Leyo edited the description of the files after I wrote here, see [1] - so its fixed :D Christian75 (talk) 20:15, 19 November 2014 (UTC)

ESIS: service closed[edit]

The ESIS website closed its service. There are lots of articles that now have a dead link: Special:LinkSearch/ I guess that we need to find alternative links as replacements. --Leyo 04:53, 19 November 2014 (UTC)

The {{chembox}} template should probably be modified for now so that the "| EINECS = " field no longer links to this website. That would eliminate most of the dead links. If an alternative link is found, it could be added to chembox later. -- Ed (Edgar181) 12:59, 19 November 2014 (UTC)
There might be a possibility to link to the ECHA search result somehow. --Leyo 18:45, 19 November 2014 (UTC)

Ethyl sulfate info box errors[edit]

I am copying comments I made on the ethyl sulfate (ethyl hydrogen sulfate) page to here. I am not sure how to go about getting this corrected.== Boiling and melting point. The boiling and melting point given are the same as for diethyl sulphate. This strikes me as very unlikely. I have verified that diethyl sulphate has the boiling and melting points listed, but I cannot find the values for ethyl hydrogen sulphate. I am almost sure that these have been mixed up, and it should say that the values are unknown if the correct values cannot be determined.Stainless316 (talk) 13:41, 13 November 2014 (UTC)

Further digging on data[edit]

This reference

gives BPt 209.5 with decomposition and MPt -25°C - exactly the same as diethyl sulfate. However, this reference also gives specific gravity/density as 1.172 - similar to diethy sulfate's wiki entry of 1.2, rather than wiki entry for ethyl hydrogen sulfate of 1.46. The reference often specifically refers to diethyl sulfate in other sections. I believe that this reference has mixed up ethyl hydrogen sulfate and diethyl sulfate. It also seems likely that this mix up has occurred elsewhere, and has been mis-applied in the wiki entry. I cannot find the boiling point and melting point of ethyl hydrogen sulfate.Stainless316 (talk) 13:12, 14 November 2014 (UTC)

I noticed this because I needed to know the boiling point for ethyl sulfate, and the incorrect information was a problem for me.Stainless316 (talk) 09:53, 25 November 2014 (UTC)
