Why Isn't Butanol More Prevalent? | Why Isn't Butanol More Prevalent?:
by Scott Sklar -- September 12, 2006
"Butanol has a high energy content (110,000 Btu per gallon for butanol vs. 84,000 Btu per gallon for ethanol). Gasoline contains about 115,000 Btu's per gallon. Butanol is six times less 'evaporative' than ethanol and 13.5 times less evaporative than gasoline, making it safer to use as an oxygenate in Arizona, California and other states, thereby eliminating the need for very special blends during the summer and winter months."
