ABSTRACT

Excess molar volumes, VmE, of six binary mixtures of ethanoic acid and propanoic acid with butan-2-ol, methyl-2-propanol, and 2-methyl-butan-2-ol were obtained from density measurements over the entire range of compositions at T = (293.15 to 333.15) K. A sigmoidal behavior was observed for the VmE values of ethanoic acid with butan-2-ol and 2-methyl-butan-2-ol, and negative VmE values were obtained for the binary mixture of ethanoic acid with methyl-2-propanol at T = (293.15 to 303.15 or 313.15) K. But the effect of the rising temperature is not the same for these mixtures. For the mixtures containing propanoic acid with alcohols the VmE values were negative and become more negative with increasing temperature over the entire range of compositions and temperatures except for the mixture of propanoic acid with methyl-2-propanol. Totally unregulated behavior was observed by a mixture of carboxylic acids with alcohols at different temperatures.
