Anyone know anything about Urethane production during wine making?
what the hack where is this page i am trying to do research and there is no page so make one
Isn't a polymer with urethane linkages called polyurethane ? This article implies just "urethane" is ok for the polymer name. H Padleckas 18:32, 24 Mar 2005 (UTC)
No, despite the names. There's a lot of pseudo science going on here. Ref 10 does NOT talk about new strains of yeast, yet the article is claiming that it does. Why does EC pose a problem in distilled drinks when its BP is 182C? Alcohol fortification rarely goes over 100C. 203.219.80.8 (talk) 03:05, 5 October 2014 (UTC)[reply]
Fully distilled spirits such as schnapps or gin should have only trace amounts of EC, if any at all. Whiskies and rums may have larger amounts of EC as a fair portion of the liquid is not distilled. TYpically in a rum a wash of molasses and proprietary ingredients is fermented separately from the distilling wash. The high alcohol distillate is then added to the separately fermented liquor, which will likely contain EC. Whiskies, made the same way, have much higher levels of available nitrogens in the washes.220.244.86.146 (talk) 00:03, 8 November 2015 (UTC)[reply]
I have added a large amount of material & references to this record on 5/14/2006.
I recommend that the title be changed back to "Urethane" because this is used more generally by regulatory agencies (EPA, NIEHS, NLM,etc.) Oldsci 19:23, 14 May 2006 (UTC)[reply]
Ok, just a little tiny peeve, it looks real weird to have i.e. separated by a auto line break like i. e. it just looks dumb. I don't know how to fix it or I would've. —Preceding unsigned comment added by 69.2.252.54 (talk) 21:27, 23 October 2007 (UTC)[reply]
I believe that urethane is often misreported for the Toxic Release Inventory, since many of the submitters of the reports confuse it with polyurethane. A few years ago I contacted each company that sent in such reports, nearly all of them responded that they misunderstood "urethane", they were reporting polyurethane, which is not to be reported.

"A few years ago I contacted each company that sent in such reports, nearly all of them responded that they misunderstood "urethane", they were reporting polyurethane, which is not to be reported."
Is there any evidence to show that this work was actually done. I'm assuming this could be as simple as proving that you worked with the EPA, or as complicated as linking some sort of survey or report that was done to show common mistakes done by companies during TRI reporting.--Spacechaser (talk) 19:47, 27 June 2011 (UTC)[reply]
Regarding the volume of "urethane" actually being produced or imported in the USA, has anyone tried to estimate the quantity needed to coat the surface of the Virginia class SSN's that were built for the Navy within the last decade? (SteveDPirate (talk) 04:41, 19 July 2011 (UTC))[reply]
The survey to check on "urethane " reporting was done by me after working for an EPA contractor. The contractor was to contact companies, by phone, that appeared to be mis-reporting certain chemicals. Many of these were prompted by disagreements of the CAS number with the name. This lead to my interest in the "urethane" reports since the manufacture or importation of "urethane" was not reportd although signifcant quantities were reported present waste streams. EPA did not seem to be interested in this discrepancy (where did all the urethane come form if no one manufactured or imported it? It has not been shown to be formed as a by-product in polyurethane production.) I contacted the companies as a pesonal project - it has not been reported anywhere. — Preceding unsigned comment added by Oldsci (talk • contribs) 02:52, 8 September 2011 (UTC)[reply]
