Ethyl Sulfate

[edit]

You surely have methyl sulphate pictured, not ethyl sulphate. —Preceding unsigned comment added by 83.104.53.26 (talk) 01:19, 17 January 2011 (UTC)[reply]

That is not true. See skeletal structure to learn where the other carbon is in this standard type of molecular diagram. DMacks (talk) 22:23, 17 January 2011 (UTC)[reply]


clarification?

[edit]

Who added all those stupid "clarification needed" tags without writing on the talk page what it is that he doesn't understand? Things seem reasonably clear at all those points. 79.234.81.201 (talk) 19:38, 3 May 2011 (UTC)[reply]

I did. There are quite explicit inline comments next to each one if you are in edit-mode. You would see them the instant you went to either improve the content there or even if you were to consider removing the tag because you think it's clear. I'll help you out and cut'n'paste from there:
  • "studied alongside" -- did he study them both separately for relationships of chemistry, or study them as a mixture for their interactions, or...?
  • "continuous process" -- did he really use Continuous production, or just repeated/bolus batch?
I look forward to any additional information you can provide here. The refs to not seem to explain it further, and the terms they use do have multiple possible meanings (either non-specific, or lay vs technical). DMacks (talk) 21:11, 3 May 2011 (UTC)[reply]

Boiling and melting point

[edit]

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)[reply]

Further digging on data

[edit]

This reference http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?sid=162221653#x27

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 referrs 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)[reply]

Delete Bpt and Mpt

[edit]

I guess I will go ahead and delete the BPt and Mpt in the info box if I don't hear anything. I have left messages in various places. Others may have access to more comprehensive data sources than I do to provide accurate data. The RSC wiki lists it as unavailable. This one lists it as 179°C http://books.google.co.uk/books?id=WJdjAwAAQBAJ&pg=PA500&lpg=PA500&dq=CAS+number+540-82-9+boiling+point&source=bl&ots=WmeKe_Ok8J&sig=62I4uLsetrpuR7AJSQkJX8F8yik&hl=en&sa=X&ei=vLp1VOPeHtbiapy3gLAD&ved=0CFkQ6AEwBw#v=onepage&q=CAS%20number%20540-82-9%20boiling%20point&f=false

This one says 280°C http://chemyq.com/En/xz/xz3/22617gbcvx.htm Rather confused picture - better to delete unless someone can verify. Stainless316 (talk) 11:52, 26 November 2014 (UTC)[reply]

I agree that removing dubious data is better than reporting it. Thanks for your efforts in trying to resolve this. -- Ed (Edgar181) 11:56, 26 November 2014 (UTC)[reply]
