摘要：

A great number of distillates of different origin were analyzed to determine the concentration of 2-butanol as well as the predominant enantiomeric form of this secondary alcohol and its excess. Chirality determinations were carried out using bidimensional gas chromatography (''heart cut'' technique coupled to GC analysis with methylated beta-cyclodextrin capillary column). Enantiomeric excesses of the R-form, ranging from 50 to 80%, were observed in all cases. This finding can be regarded as a further support to the general assumption that 2-butanol present in distillates is formed by the action of lactic acid bacteria on the mashes.
