Beschreibung

General description

Pentyl acetate is a straight chain ester. It is an odorant and its odor threshold has been evaluated by sensory panel methods. High pressure phase behavior of type I has been reported for its binary mixtures with CO₂. Solubility of these solvent mixtures was observed to increase with the rise in temperature at constant pressure.

Application

Bananenessenz. Wird als Test-Geruchsstoff in olfaktorischen Funktions-Studien und in Studien über psychosoziale Auswirkungen von Gerüchen verwendet.

Pentyl acetate may be used as odorant to compose the library of odorants to evaluate the responses of olfactory sensory neurons (OSNs) to various odorants (having different structures and odors).[1]
