Bu çalışmada, toluen-hekzan karışımının 7 farklı bileşimde 4 farklı sıcaklıkta artık hacim, artık viskozite, artık kırmaindisi ve artık Gibbs serbest enerjileri tayin edildi. Farklı sabit sıcaklıklarda yapılan ölçümlerde sabit sıcaklık ortamı sağlayabilmek için belirli ağırlıktaki bir piknometrenin etrafında bir su ceketi oluşturuldu. Bu şekilde karışımların yoğunlukları, termal denge oluşturulduktan sonra analitik olarak tartılmak suretiyle tespit bulundu. Karışımların viskoziteleri Oswald Viskozimetresi ile, kırma indisleri ise Abbe Refraktometresi ile ölçüldü. Bu ölçümlerden faydalanarak verdiğimiz bağıntıları kullanarak artık fonksiyonlar hesaplandı. Artık Gibbs serbest enerjisi ise bulduğumuz viskoziteler kullanılarak hesaplandı.
In this work, excess volume, excess viskosity, excess refractive index and excess Gibbs free energy of toluene- hexane mixture in 7 different composition and at 4 different temperatures has been determined. A water jacket around the picnometer was used to keep the temperatures constant for the measurements at different temperatures. Thus after attaining the thermal equilibrium the densities of mixtures were found by analytical balance. Viscosities and refractive indexes of the mixtures were detrmined with Oswald viscosimeter and Abbe Refractometer. Excess functions were calculated by taking advantage of these measurements of by using the equations. The excess Gibbs freee energy was calculated by using the viscosities found during the experiments from the excess thermodynamic properties.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
