Beschreibung
Zusammenfassung:	Compositions comprising 3-hexen-1-ol are described herein, as well as odor-imparting formulations comprising same and articles-of-manufacturing comprising such compositions or odor-imparting formulations. The compositions comprise trans-3-hexen-1-ol in a range of from 67% to 82% by weight and cis-3-hexen-1-ol in a range of from 18% to 33% by weight, wherein a total concentration of trans-3-hexen-1-ol and cis-3-hexen-1-ol is at least 97% by weight. Further described herein is a process for preparing a composition comprising 3-hexen-1-ol, the process comprising: contacting 1-pentene with a formaldehyde in the presence of a Lewis acid to thereby obtain a crude mixture comprising 3-hexen-1-ol; and contacting the mixture comprising 3-hexen-1-ol with a base.
