My search on the Internet for 2,5 Dimethylfuran was triggered by a page on eurekalert.org re: [James A. Dumesic's] work in converting sugars, notably fructose, to chemicals with properties of automotive fuels. Search on this topic yields roughly three insights, A) this chemical is a base for the synthesis of flavoring agents, B) little is known about it's biological effects, C) it behaves very much like gasoline in terms of flash points, boiling and freezing points, etc. I have pasted an MSDS into the main topic to publish at least something on the chemical.
[edit] "DMF"
I'm reading the nature paper and it seems quite dumb that they abbreviate this as "DMF". What about the possibility of mistaking this for N,N-dimethylformamide? --Rifleman 82 10:22, 21 June 2007 (UTC)
- That's always the danger with abbreviations. :) --Itub 10:48, 21 June 2007 (UTC)
I'm *really* uncomfortable with this compound being associated with "DMF". Apart from the original paper discussing HMF and DMF (which could well be shorthand like compound 1 and 2), is there any widespread use of DMF for this compound? If not, perhaps such references should be removed. --Rifleman 82 02:49, 23 June 2007 (UTC)
- I think too that this abbreviation has no widespread usage yet (the molecule itself had not been considered for widespread usage until recently!), but was just made up on the fly for the purpose of that paper. That is not unusual at all. I understand your reluctance to use this abbreviation in this page, but I'm not going to "vote" either way. My cynical approach to life doesn't make me uncomfortable with having confusing abbreviations because that happens all the time anyway and I have other things to worry about. ;-) The only thing I can tell you is that if this compound really gets used as a fuel and becomes commonly mentioned, it seems almost certain to me that people will refer to it as DMF, as it is the most obvious abbreviation, and its application domain doesn't overlap greatly with dimethylformamide (which is also sometimes abbreviated DMFA). --Itub 07:29, 23 June 2007 (UTC)
[edit] "Fuel Information"
For something to be considered a fuel, we should have some useful fuel information. This information is generally missing, eg here too http://cameochemicals.noaa.gov/chemical/20240#section4 These should include:-
Energy density in megajoules per kilogram,
- so that we can know the sort of power we can expect from an engine running the fuel.
Autoignition temperature,
- so that we know how much we can compress an air fuel mixture before it ignites automatically, thus giving us an idea of the highest compression ratios an engine could support (if not direct injection).
Heat of vaporization,
- so that calculated temperatures can compensate for evaporative cooling if appropriate.
Oh, and this gives a figure for the potential fuel production from algae, http://en.wikipedia.org/wiki/Algaculture, eg 5000 gallons per acre per year. Maybe we should have a similar figure for this fuel so that people can determine its viability as a commerical fuel.

[edit] Start point for synthesis
I've heard that this is a "usual suspect" as a start point for a non-petroleum chemicals industry - ethanol is not even in the league. The article should mention this. --190.56.47.173 13:54, 25 June 2007 (UTC)
- It would be great if you could add it yourself, together with a reference! Who mentions it as a usual suspect? --Itub 13:59, 25 June 2007 (UTC)
The real issue that makes 2,5 DMF a non starter as a 'biofuel' is that the synthesis requires large amounts of hydrogen, 3 moles per mole of 2,5 DMF. Hydrogen production is from oil products in Cracking Units in a refinery of from natural gas. A typical biorefinery making 50 million gallons of 2,5 DMF per year would required at least 7 Billion stnadard cubic feet of natural gas per year. At $7/million BTU, this is a cost of $50,000,000 per year. Therefore, 2,5 DMF has a significant CO2 footprint and is not such a nice biofuel. mtnclimber 16:26, 27 June 2007 (UTC)
Sounds reasonable. Do you have a good reliable source to add a referenced comment to the article? --Rifleman 82 16:35, 27 June 2007 (UTC)
