Stir Bar Sorptive Extraction of Volatile Compounds in Vinegar: Validation Study and Comparison With Solid Phase Microextraction [PDF]
, 2007 Stir bar sorptive extraction was evaluated for analysing volatiles in vinegar. The procedure developed shows detection and quantitation limits, and linear ranges adequate for analysing this type of compounds. The accuracy obtained was close to 100%, with

Synthesis of 5-Acetoxymethyl- and 5-Hydroxymethyl-2-vinyl-furan
Molecules, 2007 5-Acetoxymethyl- and 5-hydroxymethyl-2-vinylfuran were synthesized by two routes. The first route starts from 2-methylfuran and the second from furfuryl acetate. The latter route, involving successive Vilsmeier-Haack and Wittig reactions, is suitable for
