Thermodynamics of ether solutions II. Volumes of mixing of ethers with carbon tetrachloride and with chloroform at 25 °C

Abstract

A new apparatus for the measurement of volumes of mixing of liquids is described. The apparatus has been used to determine the volumes of mixing at 25 °C of mixtures of diethyl ether, di- n-propyl ether, di- n-butyl ether, di- n-amyl ether, di- n-hexyl ether, di-isopropyl ether, di-tert.-butyl ether, di-isoamyl ether with carbon tetracloride and with chloroform. The variation of volume of mixing with chain length is similar to that observed for enthalpies of mixing for the n-alkyl ethers. The effects of chain branching on volume of mixing are, however, not parallel to those on enthalpies of mixing.
