[biofuel] Looking for tests to indicate quality of Methanol
Group, I am looking for methods of analysis to indicate the water content of Methanol. I would like to do this in the "field" as it were. I have found several methods of detecting the occurence of Methyl Alcohol in Ethyl. So these tests are aimed at the foddstuffs industry rather than the quality of Methanol as being technical grade - the all desireable 98.5%. The only contaminants I will be looking for is Ethanol and Water. I don't believe there will be any other organic contaminants Specific gravity Methyl is 0.7924 Water is 1. Ethanol is 0.816 Fractional distallation Boiling Point of Methanol is 115 C Water is of course 100 C Ethanol is 78 C Any other ideas? Mark __ Do you Yahoo!? Yahoo!

If you plan to use it for biodiesel, a few percent lower purity might not matter too much. If the impurity is water though, it might matter if you're using WVO with high FFA levels. Small amounts of ethanol shouldn't matter either.

You tear off a bit, dip it in your sample. Blue means real dry (fine for biodiesel), pink means wet. It's very crude -- slightly pink will also work fine for methanol, but is way too much water for ethanol. My guess is it starts turning pink around 1.5% water. I use it all the time-K Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/ Please do NOT send Unsubscribe messages to the list address.
