1,3-Dioxanes and 1,3-Dioxolanes as Constituents of the Acetal Fraction of Spanish Fino Sherry

Abstract

Four isomeric cyclic acetals of glycerol and acetaldehyde: <i>cis</i>-5-hydroxy-2-methyl-1,3-dioxane [3674-23-5], <i>trans</i>-5-hydroxy-2-methyl-1,3-dioxane [3674-24-6], <i>cis</i>-4--hydroxymethyl-2-methyl-1,3-dioxolane [3674-21-3] and <i>trans</i>-4-hydroxymethyl-2-methyl-1,3-dioxolane [3674-22-4] were detected in Spanish fino sherry by gas chromatography and identified by mass spectrometry and Kovat9s indices.
