The reaction of propanoic acid with alcohols fits the Taft equation, log k1/kCH3 = 1.0061 Es - 0.0012, which implies that the steric effect of the substituent governs that reaction and the mechanism is similar between the different alcohols. The experimental results were modelled according to a...
The present invention designs and synthesizes the ascorbyl ester derivatives of the aryl (ethanoic) propanoic acid non-steroidal anti-inflammatory medicaments, such as ibuprofen, ke
Vapour – liquid equilibria were measured for the acetic acid + water and the propanoic acid + water systems, in the temperature range of 412.6 to 483.2 K and pressures of 1.87 to 19.38 bar, over the entire range of concentrations. An experimental apparatus based on the static-analytical metho...
The rates of elimination of several ethyl esters of 2-oxo-carboxylic acid were determined in a seasoned static reaction vessel over the temperature range 350-430°C and pressure range 33-240 Torr.The reactions,in the presence of a free-radical inhibitor,are homogeneous,unimolecular,and follow a...

Solid-liquid equilibria in the binary systems, propanoic acid-acetic acid and propanoic acid-trifluoroacetic acid, were measured by a synthetic method. A solid compound (1:1) was found in the propanoic acid-trifluoroacetic acid system. The obtained activity coefficients were successfully fitted by ...

An association model was developed to correlate the isothermal vapour-liquid equilibrium data of the binary systems propanoic acid + benzene, + n-heptane, + chlorobenzene, + cyclohexane, + tetrachloromethane and + 2-butanone, and butanoic acid + 2-butanone. The model uses a concentration-...
