Butadiene[edit]

I would have preferred if this article had stayed on the Butadiene page, instead of being moved to 1,3-Butadiene.

A lot of people who talk about 1,3-butadiene simply called it butadiene; probably most people. The 1,3-isomer is usually understood.
I think it's a good idea up to bring up front the fact that what most people call butadiene is actually 1,3-butadiene and that that a different 1,2-butadiene exists.
Some may call the compound buta-1,3-diene, adding another complication to the works.

Otherwise the article can be written as before, covering 1,3-butadiene in detail with a Table of Properties and minimally mentioning 1,2-butadiene without a Table of Properties.

I think it would be a good idea to cover or at least mention as many compounds as practicable in Wikipedia, even though there may not be enough material on individual ones to merit their own articles or their own Tables of Properties. One way to do this is to cover or mention such less important compounds in related Wikipedia articles, whether it is with or without Tables of Properties. I've started writing up a list of such compounds/articles offline with recommendations on each case, but I haven't finished yet. H Padleckas 06:17, 12 November 2005 (UTC)[reply]

I agree that this article should be moved back to its common name of Butadiene. Wikipedia practice is to prefer the most commonly used name. Anyone arguing for the present name could with the same rationale propose moving DDT to its IUPAC name 1,1,1-Trichloro-2,2-bis(4-chlorophenyl)ethane.

Phase[edit]

Liquid at 25C and b.p. -4C? 59.94.132.207 06:08, 27 June 2006 (UTC)[reply]

It is a gas at 25 C unless pressurized. I corrected the liquid density statement to reflect that it is at -6 C. --Ed (Edgar181) 11:29, 27 June 2006 (UTC)[reply]

Full Formula?[edit]

How about we put CH2CHCHCH2 somewhere? I know there's CH2=CHCH=CH2 in one of the equations, but it would be easier to have the first one, for searching the formula if someone does not know the name. 75.5.5.196 (talk) 23:59, 23 December 2007 (UTC)minidude09[reply]

belligerent[edit]

"Many of the *beligerent* nations leading up to the war.." Beligerent is not a neutral term and should be replaced by a non-offensive term. (I don't have a good one right now or I would do it) —Preceding unsigned comment added by 198.103.184.76 (talk) 18:53, 4 November 2008 (UTC)[reply]

The whole motivation theory for the invention of the butadiene-styrene copolymer replacement for rubber is not only unsourced but implausible. No one was calling Germany's Weimar Republic a belligerent in 1929 when it invented that copolymer. Russian belligerence was largely internal at that time under Stalin. And the US on the other side of the Atlantic had no designs on Europe---it took Pearl Harbor to drag it into WW2. If there's a source to the contrary then supply it, otherwise the belligerence angle for the development of the copolymer needs to go. Vaughan Pratt (talk) 04:41, 9 December 2014 (UTC)[reply]

MO scheme[edit]

I've made this if anyone's interested:

Could be useful for discussing cycloadditions (Diels-Alder reaction?).

Inclusion in camping gas[edit]

This article totally fails to state why Butadiene is included as an ingredient in camping gas canisters. What characteristic does the butadiene give the gas that would otherwise be absent? 81.129.194.138 (talk) 08:12, 8 April 2019 (UTC)[reply]

Don't hold your breath. Look at this under "Uses":

"Smaller amounts of butadiene are used to make the nylon intermediate, adiponitrile, by the addition of a molecule of hydrogen cyanide to each of the double bonds in a process called hydrocyanation developed by DuPont. Other synthetic rubber materials such as chloroprene, and the solvent sulfolane are also manufactured from butadiene. Butadiene is used in the industrial production of 4-vinylcyclohexene via a Diels Alder dimerization reaction.[16] Vinylcyclohexene is a common impurity found in butadiene upon storage due to dimerization. Cyclooctadiene and cyclododecatriene are produced via nickel- or titanium-catalyzed dimerization and trimerization reactions, respectively. Butadiene is also useful in the synthesis of cycloalkanes and cycloalkenes, as it reacts with double and triple carbon-carbon bonds through the Diels-Alder reaction."

Wikipedia should explain the world to the layman. Nobody without a degree in chemistry would learn anything from this self-indulgent wank written by someone who doesn't know the difference between an encyclopedia and a textbook. Patrick Neylan (talk) 00:49, 30 April 2021 (UTC)[reply]

@Patrick Neylan: Please suggest changes. The opening paragraph seems straightforward with simple sentence structure:

"1,3-Butadiene (/ˌbjuːtəˈdʌɪiːn/)[4] is the organic compound with the formula (CH2=CH)2."
- We say what it is, and we give a chemical formula, we instruct readers on the pronunciation. What else should we say in the first sentence?
"It is a colorless gas that is easily condensed to a liquid."
- we describe its appearance. This info seems key and non-wonkish. You see this statement as too advanced?
"It is important industrially as a monomer in the production of synthetic rubber."
- that is the reason this chemical compound is used. It seems that readers might want to know why anyone cares about butadiene. Is this statement to advanced or written strangely?
"The molecule can be viewed as the union of two vinyl groups. It is the simplest conjugated diene."
- that statement is admittedly jargon for readers with chemical knowledge. Wikipedia is here not just for layfolk ...

@Smokefoot. That wasn't the paragraph I was criticising. The paragraph I quoted is comprehensible only to qualified chemists. The only people who need to know it but don't already would be chemistry students, who should be consulting an academic textbook and not Wikipedia. Users of an encyclopedia aren't looking for: "This chemical you've never heard of is used to make these other chemicals you've never heard of via this process that you don't understand." They're more likely to want something along the lines of: "Butadiene is used to make synthetic rubbers for the manufacture of tyres, grommets and elastic bands. When mixed with propylene it is also a powerful aphrodisiac, as well as being a thickener for sauces in Thai cuisine."Patrick Neylan (talk) 16:21, 30 April 2021 (UTC)[reply]

Formation of "Popcorn Polymer".[edit]

This may not be the place for this question. Could someone include the subject of popcorn polymer to this article? The CSB just released a video on an incident. From U-Tube description - "A CSB safety video on the November 2019 incident at the TPC Group Chemical Plant in Port Neches, Texas. A series of explosions destroyed a portion of the TPC facility, damaged nearby homes and businesses, and prompted a mandatory evacuation of residents living within four miles of the plant. Several workers and members of the public reported injuries and fires burned at the facility for over a month. The incident caused $450 million in on-site property damage and $153 million in off-site property damage to nearby homes and businesses. Media reports indicated that the blast was felt up to 30 miles away." Link - https://www.youtube.com/watch?v=6-3BFXpBcjc Thank You Drsayle (talk) 17:59, 19 July 2023 (UTC)[reply]

You are free to edit and include it yourself. It looks like the chem industry has been actively rummaging through Wiki, cleansing every reference to it's safety failures.47.248.163.166 (talk) 02:02, 16 November 2023 (UTC)[reply]

What's the correct nomenclature for this molecule?[edit]

The page is titled 'Butadiene', refers to the molecule as 1,3-butadiene, and says in the infobox that the preferred IUPAC name is buta-1,3-diene. It makes sense (by the discussion above) that the article is titled by the common name 'butadiene' , but which (of the last two) is the correct formal name for this molecule? It seems confusing to refer to it by two different names, or by a name that isn't the preferred one. CosmicSpirol (talk) 12:06, 19 November 2023 (UTC)[reply]
