The application of the principle of congruence to multicomponent mixtu
res was tested in a novel way by mixing a symmetrical ether of side ch
ain carbon number m with an equimolar mixture of two symmetrical ether
s such that their average side chain carbon number was m. The equimola
r mixture was known as a pseudo-ether of carbon number m. Excess molar
enthalpies and volumes were measured using these mixtures at atmosphe
ric pressure and at 298.15 K and the results used to test the principl
e of congruence. The process was repeated for mixtures of ketones and
pseudo-ketones. (C) 1997 Elsevier Science B.V.
