Abstract
Abstract Thirteen chemists representing twelve laboratories participated in a collaborative study for the quantitative determination of ethyl acetate and fusel oil by GLC. The results on four samples containing various amounts of ethyl acetate and fusel oil were compared with the official AOAC procedures. For all samples, the standard deviations were lower with GLC. Collaborators preferred the GLC procedure because the simultaneous determination of ethyl acetate and n-propyl, iso-butyl, and isoamyl alcohols is possible. Results from preliminary work performed on the quantitative determination of acetaldehyde by GLC were encouraging. It is recommended that the proposed GLC procedure for the quantitative determination of ethyl acetate and fusel oil be adopted as official, first action, and that work be continvied on the determination of acetaldehyde by GLC.
