Urethane

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

sheesh. 100k+ articles of free content, and still the readers complain :-( you're just going to have to do your research somewhere else, then come back and tell use all about it -- Tarquin 23:42 Mar 11, 2003 (UTC)

To be fair, back in 2003 something like 100 of those pages were anything resembling "content"... so it was still 100x better than youtube at least. There's still the issue where anyone wanting to make stuff up just needs to reference a book that's nearly impossible to find regardless of what it says, or even an open access journal article (since people rarely read them to verify that they have anything to do with the text they're tacked onto) I generally find that they just don't have anything to do with it and were probably found in a keyword search and added without even reading the abstract, which is kinda what you get when high school teachers tell their students to pick a page to edit and add "peer reviewed references" to articles.

I rarely find a page without at least one unreadable abomination of English (which nevertheless tends to look like the kind of headline our local newspaper and news channel write these days. They love forgetting things like indirect objects and verbs.) so it's more a sign of some society-wide degradation of language than anything specific to Wikipedia, IMO. Maybe low level chlorofluorocarbon exposure was actually raising intelligence and as it's phased out everyone gets dumber... or more likely everybody just writes in emojis and sits staring at their phone even when they're in the same place as one another until they forget how to communicate.

Anyway as Wikipedia got more detailed the "what the hack where is this page" guy was no longer even able to figure out what to plagiarize and is now busy paying for tokens to ask ChatGPT his homework questions (its been over 21 years but I'm not ruling out middle school) / the JS and python he does for a living instead and pasting the answer into a .docx file to email his teacher / boss, who just feeds it into an expensive third party tool the school uses to check for plagiarism and / or ships it to customers without looking since they're busy fapping for their onlyfans and cant be bothered.--A Shortfall Of Gravitas (talk) 19:51, 28 October 2024 (UTC)

Polyurethane = polymer with urethane linkage

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)

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)

Changes & Recommendation to Ethyl Carbamate

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)

I would recommend against this. Wikipedia policy is to have the most common usage as the page title. Ethyl carbamate isn't so frequently encountered as a chemical. More often the word "urethane" is used colloquially for polyurethane or to refer to the carbamate functionality. If you feel strongly that the page should be moved back the procedure is to list it at Wikipedia:Requested moves, following the directions there. Dr Zak 15:00, 15 May 2006 (UTC)

i. e.

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)

TRI misreporting

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)

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))

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)
