31. The original 1899 publication concerned the conversion of " n "-butanol to 2-ethylhexanol. 32. From the little I've read, it sounds likely that SwiftFuel is an ethanol-butanol mix. 33. It is manufactured by the esterification of acetic acid with n-butanol in the presence of suitable acid catalyst. 34. Therefore, companies like BP and DuPont have been looking at the next generation of biofuel, specifically investigating butanol . 35. Butanol production from glycerol is economically viable using metabolic pathways that exist in " Clostridium pasteurianum " bacterium.36. In 2012 researchers developed a method for storing electrical energy as chemical energy in higher alcohols ( including butanol ). 37. However, the production of butanol from glycerol by fermentation in " C . Pasteurianum " is low. 38. For this reason, butanol is used as an alternative to shorter alcohols when a more viscous solvent is desired. 39. I thought of this issue a while ago, but say you start out with 1-butanol or something. 40. Volatile esters of 2-butanol have pleasant aromas and are used in small amounts as perfumes or in artificial flavors.
