Talk:Propane

message: I don't know if the crystal structure of propane is important enough to be included in this article. Maybe it would be better placed at Alkane#Melting point as an example of the crystal structure of an odd-numbered n-alkane (these have lower melting points due to poorer packing than even-numbered n-alkanes) . Any views, anyone?

replies: text: It is very difficult for this to occur, and tv/video games usually greatly exaggerate the extent to which this can happen. Most pistols would not actually rupture the tank. It would require a tremendous blow from something far more destructive and unfortunately there isn't a great "reference" to cite here. It would likely require incendiary ammo or tracers of some sort to cause an explosion via projectile/gunfire with an ignition factor. propaneprices (talk) 18:44, 17 March 2016 (UTC)

message: There is substantial overlap between the content of Liquefied petroleum gas and that of Propane. In general, Propane is of higher quality. I suggest we extract the useful and well-referenced content from LPG, add it to Propane, and make a redirect. —Scheinwerfermann T·C07:14, 29 April 2009 (UTC)

message: Hello,  I found your note and wish to respond.  The article on propane under the energy content section contained an error, a statement similar to 40.2 kJ/g ... 50 MJ/kg which contradicted itself.  As this did not answer the question and contained conflicting information, I went on a search taking much time and aggravation to find the correct answer to my question of how much energy is released by the combustion of propane.  I found the information which I considered to be reliable at the NIST, and so, having found my answer I thought to share it with Wikipedia.  I do not appreciate your removing the efforts of my work.  As it is from the NIST I doubt you can find it inaccurate, so I am left wondering why you so deliberately chose to re-edit the section.
Per the National Institute of Standards and Technology (NIST), the heat of combustion of propane is -2219.2 kJ/mol ± 0.46 kJ/mol. The molecular weight of propane is 44.09562 g/mol, and this comes out to be 50.327 MJ/kg ± 0.0104 MJ/kg.

replies: text: Please don't correct -2219.2 ± 0.5 to -2219.2 ± 0.46, which is not a scientific presentation of accuracy. (The accuracy of 0.46 is "too accurate" and should be rounded to 0.5, except for some special cases, which this one is not). Further, even the NIST link gives a spread between different datasets.

message: According to the history section on this page, propane was first identified in 1910. However, I've found a reference dating from 1873 that mentions propane, with the correct formula and all! What exactly is the meaning of this?

replies: text: The problem is that that probably isn't true, and even if that wasn't the case the discovery of propane itself most definitely should be included in a history section on it.SQMeaner (talk) 05:52, 16 April 2017 (UTC)
replies: text: You are missing something.  It has been known for a long time, no real discovery involved.  Finding it in gasoline made it an industry.  Union Carbide, Phillips Petroleum and others began selling it as it was available to them.  The removal from gasoline made gasoline a bit more stable and easier to deal with.JSR (talk) 11:54, 16 April 2017 (UTC)
replies: text: Surely somebody was the first to give it a name or document its formula? Anyway, I am inclined to agree that, without any further info, the phrase "Propane was first identified as a volatile component in gasoline..." is prone to being misinterpreted by readers without background knowledge as referring its initial discovery. It is the very first sentence of the History section so they might well think that is the very start of its history. Adding a sentence or two before it to explain the initial discovery and its naming would do no harm. That said, the same is true for many articles like this. Neither Butane nor Pentane mentions who discovered/named/classified them, or when, while Ethane does, what I consider to be, a much better job. --DanielRigal (talk) 12:15, 16 April 2017 (UTC)

thread_title:  Refilling Stations for LP Gas 

message: This article has no mention of the use of propane as a compressed gas for applications which previously used CFCs, such as aerosol propellants and canned air. In Germany at least, aerosol deodorants, canned air, etc. are typically labeled as using propane as the propellant, whereas Aerosol_spray#Aerosol_propellants says "The most common replacements of CFCs are mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane." I don't know whether actual consumer applications in 2021 tend to use propane or a mixture, or if this varies by country or application.
Now, I see that Airsoft lists the compressed gases commonly used in the sport as "e.g. propane ("green gas"), 1,1,1,2-tetrafluoroethane or CO2". How green is propane? Methane is, famously, a more potent greenhouse gas than CO2; is unburnt propane a greenhouse gas? What is its environmental fate - does it degrade without producing methane as an intermediate product?
This article should therefore have a section on the use of propane as a compressed gas, either alone or in a mixture. 1) What are the relevant properties of propane, e.g. vapor pressure? 2) What are its pros and cons compared to alternatives? (Nontoxic, but flammable, etc.) 3) What is the environmental effect of unburnt propane? 4) What is the scope of use of propane? (E.g. consumer applications or also industrial? Germany or Europe or worldwide? If there are regional differences, is this due to legislation or availability or...?) SSSheridan (talk) 09:15, 25 November 2021 (UTC)
