Any body have any idea about furfural synthesis ?
825999
Furural is obtained industrially by the acid hydrolysis of the polysaccharides of oat hulls, corn cobs, or straw. These polysaccharides are built up from pentose units. Dehydation of the pentose occurs to give furfural (2-furaldehyde).\n\nCHOCHOHCHOHCHOHCH2OH +H^+ -----> cyclicC5H4O2\n\n(Formaldehyde with a furan attached to it. Attachment is on C1 of furan)

G E R A N Y L GERANIOL has been proposed by some\nauthors as an intermediate in the biosynthesis of di- and\ntricyclic diterpenes.\n\nAccording to Wagner and Jaureg  and Kuhn and\nGrundmann  it would be transformed into phytol by\nhydrogenation and into lycopene and other carotenoids\nby dehydration and dimerization. Ruzicka suggested \nthat geranyl geraniol and geranyl linalool might be the\nprecursors of the di- and tricyclic diterpenes respectively ;\nbut although geranyl linalool has been isolated, together\nwith phytol and isophytol, from jasmine essential oil by\nDemole and Lederer , these authors were unable to\nisolate geranyl geraniol from the same source, probably\nbecause it is rapidly metabolized.\nAccording to some recent work of Costes , geranyl\ngeraniol and geranyl linalool are precursors of carotene\nand lutein. Stobbe  has proposed geranyl geraniol as\nan intermediate in the biosynthesis of vitamin Kz.\nPopjak  has found, by gas-liquid chromatography\nof the unsaponifiable fraction of liver homogenate incubated\nwith ~~-mevalonate-2-"C, two peaks with the\nretention volumes expected for geranyl linalool and\ngeranyl geraniol. These were minor constituents of a\nmixture consisting predominantly of nerolidol, alltrans\nfarnesol, methyl allyl alcohol, linalool, nerol, and\ngeraniol.\nGeranyl geraniol has, to our knowledge, never been\nisolated from natural sources and fully characterized although\nit has been shown to be synthesized by cell-free\nenzyme systems . This article describes the isolation\nand identification of geranyl geraniol from the unsaponifiable\nfraction of linseed oil. We have also obtained\nit from the corresponding fraction of peanut oil.\n\nFor the separation of the unsaponifiable fraction, an\nItalian linseed oil was utilized. For comparison, samples\nof phytol and farnesol were purchased from British Drug\nHouses (Poole, England) and Fluka A.G. (Basel,\nSwitzerland).\nColumn Chromatography. Alumina (Activity 111) in\npetroleum ether (bp 60-80°C) was used to fractionate\nthe unsaponifiable fraction, and silicic acid (Mallinckrodt\nChemical Company, St. Louis, Mo.) for the separation\nof phytol from geranyl geraniol. Details are given in\nResults. After separation, each fraction was recovered\nand weighed, and its composition was checked by TLC.\nFor thin-layer chromatography, 20 X 20 cm plates, 0.25\nmm thick, prepared with Silica Gel G (Merck & Co.,\nInc.) were used. Substances were detected by charring\nwith sulfuric acid or spraying with 2,7-dichlorofluorescein\n(sodium salt) in alcohol.\nGas liquid chromatography :\nBoth polar and nonpolar\ncolumns were used. The nonpolar coliiinn was used in a\nFractovap model C-AID/F chromatograph (Erba,\nMilan) with flame ionization dctcctor. It was 2 m X 4\nmm I.D. and contained SE-30 (methylpolysiloxy giiin,\nGeneral Electric), 1% on silanized Gas-Chrom P,\n100-200 mesh, at 190°C. The flash heater was at 250'C\nand the carrier gas was nitrogen, 40 ml/inin.\nThe polar coluinn, in a Fractovap model B with\nthermal conductivity detector, contained ethylene glycol\nsuccinate polyester, 20% on Chrornosorb W, 60-80\nmesh. Column, 210'C. Flash hcatcr, 250°C. Carrier gas.\nhelium, 4.5 liters/hr.\nInfrared spectra were recorded on a Perkin-Elmer\nInfracord apparatus.

Probably not on the web.  Do a web search on the final product, read the hits, and see if the journals mentioned are on line or contact the authors (be very polite!!! if you want feedback).  If not you will need the library.  The book series Inorganic Syntheses should have it.

Hey my research topic also includes it. I use Smethyl thiourea for doing so. check out my site\nGoto projects and then goto view documents. there you will find various patents. goto oxadiazine synthesis patent

Hey that's worth a shot although i think ill need a couple kilo's of sugar, couple of slices of bread, some vitamin B to get the process going. but then again the carbon dioxide produced by the ferment will kill me. oh well back to the drawing board.

I've done some research on this because I seem to remember my teacher talking in school about how they can make batteries with graphite (pencil lead) and vinegar that put out more energy and are more environmentally safe than regular batteries. I'm not sure how this happens but I know that you can take vinegar and pour some into powdered graphite, rub it into a block of wood, and when the vinegar dries the wood will be extra strong because the vinegar disolves the graphite long enough for it to bind to the wood. I can't find any research or projects to back this up but that is what I remember on the subject. Perhaps you could split a pencil and drop the lead in for a few days and see? Maybe use two and a nine volt battery and see what a current does to affect the chemical process...I wish I could help you more.

Hey cable_ray,\n     One of the most easiest way to get the recipie you require or any other synthesis can be found on the following website. It is the organic synthesis website, maintained by cambridgesoft.com. It is a free service they provide. You can use it. Just put in the name of the ether you want to produce eg. dimethyl ether, diethyl ether, etc. I am an MSc by research student. So you can also mail me. I will surely reply. my mail add is jchemie@gmail.com
