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

香蕉香精。作为试验气味剂用于嗅觉功能研究和气味的社会心理效应研究。
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).
