Re: Help with MS Encarta Encyclopedia - Ethanol?



Greg,

For an "off-the-cuff" answer:

Ethanol is grain alcohol.  It is blended with ordinary gasoline to make a 
mixture called "gasohol".  It sez here that this mixture burns cleaner 
and reduces emissions.  I'm not so sure.  I think the jury is still out 
on that one.  One thing is for sure, it makes lots of money for Archer, 
Daniels, Midland (ADM) who produce large quantities of ethanol from grain 
for this purpose.  Ethanol is CH3-CH2-OH.  Methanol is CH3-OH and is 
commonly referred to as "wood alcohol" and is made synthetically. Gasohol 
became "popular(?)" in much of the country during the oil shortage of the 
70's.  It was more popular in corn producing states than in others as I 
recall.  :-)

The effect of added ethanol (or methanol) in gasoline is more or less the 
same effect as added methyl tertiary-butyl ether (MTBE) which is now 
required by law in certain regions during the winter months.
