Dielectric constant of the mixture (1) ethyl butanoate; (2) heptanestatic dielectric constant of binary liquid mixturesThis document is part of Volume 17 `Static Dielectric Constants of Pure Liquids and Binary Liquid Mixtures (Supplement to IV/6)' of Landolt-Börnstein Group IV `Physical ...
Two series of mixtures of ethylammonium butanoate (EAB, [N0 0 0 2][C3CO2]) in water and N-methyl-2-pyrrolidone (NMP) have been prepared at different molar fractions to assess the effect of these two polar solvents on the nanostructural order present in [N0 0 0 2][C3CO2]. The small...
In this work, the measurements of the isobaric vapor–liquid equilibrium (VLE) data at 101.32 kPa and the excess molar volumes (vE), obtained at 10 K intervals of temperature in the range (288.15 to 328.15) K, for four binary systems comprised of methyl or ethyl butanoate with two alkanes...
In addition, ethyl lactate, ethyl acetate, and ethyl butanoate, which have high content as well, are collectively known as the “four major esters” with ethyl hexanoate of strong-aroma baijiu. Moreover, the content of organic acids is next to ester, with a total content of 140 mg/100...
34 detected terpenes (sylvestrene), aldehydes (nonanal and decanal), and esters (ethyl propanoate, 2-methyl ethyl propanoate, 2-methyl ethyl butanoate, and 3-methyl butyl acetate) as some of the cues that attract G. melonella to honeycomb volatiles. These cues may be significant in mediating...
