Abstract

Son birkaç on yılda, endüstride mikrodalga (MW) spektroskopi uygulamalarının kullanımı önemli ölçüde artmıştır. Bu teknik, dielektrik parametrelerin (Ɛ’ ve Ɛ”) ölçümü yoluyla alkol-su karışımları hakkında çok önemli ayrıntılar vermesi nedeniyle oldukça kullanışlıdır. Bu çalışmada, saf sudan saf alkole doğru konsantrasyon değişimleri için etanol-su ve metanol-su karışımlarının dielektrik parametreleri (Ɛ’ ve Ɛ”) belirlendi. Etanol-su ve metanol-su karışımlarının dielektrik parametrelerinin (Ɛ’ ve Ɛ”) kırılma noktalarının %43 ve %44 hacim fraksiyonlarında, xet≈ 0.20M ve xmet ≈ 0.26M molar fraksiyonlarında olduğu tespit edildi.

Investigation of Dielectric Constants of Alcohol-Water Mixtures by Microwave (MW) Spectroscopy Technique

Abstract

Over the last few decades, the utilization of microwave (MW) spectroscopy applications in industry has grown dramatically. This technique is very useful as it gives very important details about alcohol-water mixtures through the measurement of dielectric parameters (Ɛ’ and Ɛ”). This research determined the dielectric parameters (Ɛ’ and Ɛ”) of ethanol-water and methanol-water mixtures for concentration changes from pure water to pure alcohol. The ethanol-water and methanol-water mixture volume fractions of 43% and 44%, respectively, as well as the molar fractions xet≈ 0.20M and xmet ≈ 0.26M, obtained the breaking points of the dielectric parameters (Ɛ’ and Ɛ”).

Keywords
