Densities, and refractive indices were measured for the binary system ethanol + 1-nonanol and ternary system ethanol + 1-nonanol + water at 293.15 K. The excess molar volumes, and the deviations molar refraction were calculated for binary and ternary system. Redlich-Kister type equation was fitted to the excess molar volumes and, the deviations from a mole fraction average of the molar refraction, and the values of coefficients were calculated

Keywords: 1-nonanol, Ethanol, Density, Refractive indices, Binary mixture

Etanol+1-nonanol ikili sistemi ve etanol+1-nonanol+su üçlü sistemi için çeþitli karýþýmlarda yoðunluklar ve kýrýlma indisleri 293.15 K de ölçülmüþtür. Ýkili ve üçlü sistemler için aþýrý molar hacim ve molar refraksiyon sapmalarý hesaplanmýþtýr. Aþýrý molar hacim ve molar refraksiyon sapmalarý için Redlich–Kister eþitliði uygulanarak eþitlik katsayýlarý hesaplanmýþtýr.

Anahtar Kelimeler: 1-nonanol, Etanol, Yoðunluk, Refraktif indis, Ýkili karýþým
