Different chemical. Short chemistry lesson: Methyl hydrate is an old name for methanol, which is a chemical compound (molecule) consisting of one carbon, one oxygen, and four hydrogen atoms. Ethanol, the alcohol we love to drink, has two carbon, one oxygen, and 6 hydrogen atoms in each molecule. In general, a hydrocarbon is a compound made up of just carbon and hydrogen atoms. If you substitute an oxygen atom which is also linked to a hydrogen atom for one of the hydrogen atoms in a hydrocarbon molecule, you then have an alcohol. The -OH is know as a hydroxyl group, and when attached to a hydrocarbon to form an alcohol, is responsible for most of the resultant compound's chemical activity. Most but not all. That is why the various alcohols are similar but different, and particularly different in how toxic they are to humans.
Dwight might have something to add, but that is it in a nutshell.

You can get further only with molecular sieves or by removing the remaining water using benzene or some other substances. The best (for drinking, if you are so inclined) is this one: http://global.rakuten.com/en/store/sakemitsui/item/vod-0007/ (btw. the web page says incorrectly 96 degrees, it is 96%). In Canada, you can get it in Quebec as Global Alcool, but it is “only” 94%. However, I would not use it in a stove, as it would not be overly cost effective. It has great applications for mixing drinks, though.

This article concludes that ethanol is the more efficient fuel. http://vincent02pd2011.wikispaces.com/Methanol+Vs+Ethanol+Fuel+Lab and this article says that ethanol produces a higher flame temperature. http://classroom.synonym.com/burns-hotter-ethanol-methanol-7848.html Ethanol is hygroscopic and will absorb up to 5% moisture from the atmosphere. It is difficult to obtain and store 100% pure ethanol. Many chemicals can be used to “denature” ethanol, like methanol, acetone, benzene, isobutyl ketone and most of these chemicals will make the denatured ethanol poisonous , bad tasting, bad smelling or nauseating in order to discourage human consumption Dwight Veinot C&C 35MKII, Alianna Head of St. Margaret's Bay, NS ------------------------------------------------------------------------------ From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Marek Dziedzic via CnC-List Sent: August 12, 2014 9:12 AM To: Stevan Plavsa ; cnc-list@cnc-list.com Subject: Re: Stus-List Alcohol stove Steve, try other marine stores. In Ottawa , The Chandlery, sells Capt. Phab 4l for $21.50 (or $20 US) (http://www.thechandleryonline.com/product_info.php?products_id=3331). I think they would ship it, unless there is some funny restriction. They ship to the US , as well. Marine Outfitters out of Kingston carry it, too. Btw. this is what I use in my stove and it burns extremely clean.

I found it at this place finally: http://www.sculpturesupply.com/index.php I paid something less than $25 for a 4 litre jug. Much better deal than the stuff they sell at west marine.

About once a year I go to Lowes and buy a gallon can. And one of these days I'll finally get around to installing the new propane stove I bought for the 38 a couple of years ago. I'm told it is easier to find propane than denatured alcohol when you are in the Bahamas or the Caribbean .

Cleaned it up filled it and brewed a big pot of coffee in no time. Is there any reason not to use plain old denatured alcohol instead of stove cooking fuel?
