Dear Mr. Bob Allen: I agree 100% with you. Thanks again. Mr. F.j. Burgos ----- Original Message ----- From: "bob allen" <[EMAIL PROTECTED]> To: <Biofuel@sustainablelists.org> Sent: Monday, November 21, 2005 9:37 PM Subject: Re: [Biofuel] Absolute ethanol
Francisco, there is still some 4 or 5 % missing here. My only concern is that the missing per centage is water. It says .2% water but it doesn't add up. If the missing mass is water, it won't work. Water makes soap, not biofuel. And with ethanol it is very, very important. If the remainder is a hydrocarbon denaturant, then it should be no problem as small amounts of hydrocarbons don't interfere. My recommendation is try it on a small scale and see if it works. good luck francisco j burgos wrote: > Dear Mr. Bob Allen: > Here are label indications > > ETHANOL 95% > ABSOLUT ETHYL ALCOHOL > > Minimum Assay: 95% (V/V) Boiling point 78.5 ºC (br 0.5ºC) > Density: 1 L = 0.79 kg > MAXIMIM LIMITS OF IMPURITIES > Acidity (acetic acid) 0.001% > Alkalinity (NH3) 0.0001% > Carboxilic compounds (CO) 0.00005% > Color (APHA) 10 > Isopropyl alcohol 0.003 > Methanol 0.01 > Residue on evaporation 0.001% > Substances reducing (09 5m 0.0003% > H2O 0.2% > Al 0.00005% > Thanks, > Mr. F.J.
