Liquid–liquid equilibrium in binary systems of isomeric C8 aliphatic monoethers with nitromethane

Abstract New apparatus to measure liquid–liquid or solid–liquid equilibria by a synthetic method has been built and described. It was used to determine the liquid–liquid equilibrium curves for four binary mixtures of nitromethane + {heptyl methyl ether–CH 3 O n C 7 H 15 , or ethyl hexyl ether–C 2 H 5 O n C 6 H 13 , or pentyl propyl ether n C 3 H 7 O n C 5 H 11 , or dibutyl ether n C 4 H 9 O n C 4 H 9 }. The influence of position of the ethereal group on the solubility curve has been discussed.
