✦ Synopsis

Excess volumes of each of six methyl esters (from pentanoate to pentadecanoate) with each of five odd n-alkanes (from pentane to tridecane) have been obtained at the temperature 298.15 K using a vibrating-tube densimeter. The V E m values were positive for the mixtures containing the heavier hydrocarbons and the slighter esters and negative in the other cases. The results for V E m are compared with those obtained using several theoretical models; however the estimations were not good.

Excess thermodynamic functions H E m and V E m are reported in this paper for a set of 42 mixtures formed by six ethyl alkanoates (from ethanoate to heptanoate) and seven odd alkanes (from pentane to heptadecane). The H E m values were positive for all mixtures, increasing with the alkane chain-leng
