ABSTRACT

Densities, viscosities, refractive indices, and surface tensions for 12 flavor esters were measured from 288.15 K to 358.15 K at atmospheric pressure. The esters studied were ethyl acetoacetate, isoamyl acetate, ethyl isovalerate, methyl benzoate, ethyl caproate, ethyl benzoate, benzyl acetate, isoamyl butyrate, ethyl salicylate, benzyl propionate, ethyl phenylacetate, and ethyl caprylate. Densities were determined using a vibrating-tube density meter, and viscosities were measured with an automatic Ubbelohde capillary viscometer. Refractive indices were measured using a digital Abbe-type refractometer, and surface tensions were measured using the Wilhelmy-plate method. The experimental data were correlated by temperaturedependent equations.
