Abstract
A great number of distillates of different origin were analyzed to det ermine the concentration of 2-butanol as well as the predominant enant iomeric form of this secondary alcohol and its excess. Chirality deter minations were carried out using bidimensional gas chromatography (''h eart cut'' technique coupled to GC analysis with methylated beta-cyclo dextrin capillary column). Enantiomeric excesses of the R-form, rangin g from 50 to 80%, were observed in all cases. This finding can be rega rded as a further support to the general assumption that 2-butanol pre sent in distillates is formed by the action of lactic acid bacteria on the mashes.
