I am looking for the heat capacity of Tetrahydrofuran (THF). THF is an s-II promotor.
I would like to see information on the commercial uses of this chemical as a solvent / adhesive.
Perhaps someone from a manufacturing facility might be willing to contribute general topic information.

It is used as an adhesive for pvc liners for landfills and similiar applications. —Preceding unsigned comment added by 74.99.38.139 ( talk) 02:23, 7 August 2010 (UTC)
Diethyl ether can often be substituted with THF, especially when a higher-boiling solvent is required
But according to the THF and Diethyl Ether pages, THF has the higher BP - 66 degrees C for THF and 34.6 degrees C for Diethyl Ether - so either this part of the article is wrong, or there is an error in the boiling point figures. Royhills 23:24, 1 February 2007 (UTC)

Under the header Precautions, it says: "THF can be stored in air-tight bottles in the dark over sodium hydroxide"
But in an MSDS ( https://fscimage.fishersci.com/msds/23010.htm, https://fscimage.fishersci.com/msds/23011.htm), "caustic alkalis" are mentioned among "Incompatibilities with Other Materials".
Is dry NaOH ok?
Whomever thinks the smell is similar to diethyl ether needs their nose examined. Ether is cloyingly sweet while THF smells more like moldy basement. 24.127.45.84 ( talk) 01:48, 26 March 2008 (UTC)
I've worked with it for a while and it smells like acetone. —Preceding unsigned comment added by 74.99.38.139 ( talk) 02:25, 7 August 2010 (UTC)
I'm familiar with all of the above, and it doesn't smell anything like acetone! (I've just randomly sampled a couple of labmates, and they agree the above poster is talking rubbish.) Maybe if those are the only two organic chemicals you've ever smelled. A former coworker referred to the smell of THF as "like cat p***"... 192.17.28.26 ( talk) 15:18, 20 October 2015 (UTC)
I have checked the GHS about the LD50 values of THF and ACE. THF oral:2842mg/kg(rat) ACE oral:5800mg/kg(rat)
As I know, the lower the LD50 is, the higher the toxicity is. So it should be "THF is relatively toxic solvent than ACE." —Preceding unsigned comment added by 140.113.165.235 ( talk) 04:50, 14 July 2010 (UTC)
Why not just say how toxic it is, instead of saying its toxicity is comparable to aceton; surely that would be more encyclopaedic ? Otherwise you have to go check the aceton article, and who knows, maybe there it says it's as toxic as something else too. 78.23.228.141 ( talk) 21:41, 9 June 2012 (UTC)
"relatively acutely nontoxic" What? Surely "relatively nontoxic" is sufficient? BioImages2000 ( talk) 11:52, 30 October 2022 (UTC)
@ LeticiaLL:, I've removed this from the article;
1,4-dioxolane is known as 1,4-dioxane, its derivatives are called "dioxanes"
I don't think 1,4-dioxolane is a synonym for 1,4-dioxane. Dioxolanes are pentic and dioxanes are hexic. 1,4-dioxolane is the same isomer as 1,3-dioxolane. Spinning Spark 17:49, 30 June 2020 (UTC)
