Abstract

Penelitian ini bertujuan untuk memperoleh data kesetimbangan uap-cair(VLE) isothermal sistem biner 2-butanol + dietil karbonat dan tert-butanol + dietil karbonat pada suhu 303.15- 323.15 K yang akurat dan mengkorelasikan data eksperimen dengan model Wilson, NRTL, dan UNIQUAC. Peralatan eksperimen yang digunakan adalah ebulliometer sederhana yang telah dikembangkan di Laboratorium Thermodinamika Teknik Kimia ITS. Eksperimen diawali dengan mengukur tekanan uap murni masing-masing komponen menghasilkan deviasi kurang dari 0.8% dibanding data literatur. Kemudian dilakukan pengukuran tekanan uap campuran biner dengan rentang fraksi mol 0-1. Dari hasil eksperimen, diketahui semua sistem yang diteliti menunjukkan deviasi positif terhadap hukum Raoult dan perilaku azeotrop ditemukan untuk sistem 2-butanol + DEC pada semua rentang temperatur eksperimen. Data eksperimen untuk sistem tertbutanol (1) + DEC (2) yang dikorelasikan dengan model Wilson, UNIQUAC, NRTL memberikan AAD sebesar 1.3% untuk semua model, dan untuk sistem 2-butanol (1) + DEC (2) memberikan AAD 1.5% untuk model Wilson dan UNIQUAC serta 1.4% untuk model NRTL. ================================================================= The objective of this research was to measure isothermal vapor-liquid equilibrium (VLE) data for binary systems of 2- butanol + diethyl carbonate and tert-butanol + diethyl carbonate in temperature range of 303.15-323.15 K accurately and correlating the experimental data with Wilson, NRTL, and UNIQUAC models. The experimental apparatus used was the simple ebulliometer developed in Thermodynamics Laboratory of Chemical Engineering ITS. The experiment was started by measuring the vapor pressure of each pure component giving Average Absolute Deviation (AAD) of less than 0.8% compared to the literature data. Furthermore, the measurement of vapor pressure mixture of binary with the mole fraction range of 0-1. From the experimental results, it was found that all the systems studied show a positive deviation from Raoult’s law and the azeotropic behavior was found for 2-butanol + DEC system. The experimental data for the tert-butanol (1) + DEC (2) system were correlated with the Wilson, UNIQUAC, NRTL models giving 1.3% AAD for all models, and for 2-butanol (1) + DEC (2) systems giving 1.5 % AAD for Wilson and UNIQUAC models and 1.4% for the NRTL model.
