Abstract
Tujuan dari penelitian ini adalah untuk mendapatkan data kesetimbangan cair-cair sistem quaterner eugenol + β-caryophyllene + 1-propanol + air pada temperatur 303,15; 313,15; dan 323,15 K. Data kesetimbangan diperoleh dengan mengaduk campuran komponen murni tersebut selama 4 jam sehingga menjadi homogen. Campuran kemudian didiamkan selama 20 jam agar kondisi kesetimbangan tercapai. Setelah itu, sampel dari kedua fase cair yang terbentuk dianalisis komposisinya menggunakan Gas Chromatography (GC) untuk mendapatkan komposisi masing-masing komponen pada tiap-tiap fase. Data eksperimen yang diperoleh kemudian dikorelasikan menggunakan model UNIQUAC dan NRTL dan kemudian membandingkan hasil korelasi dengan eksperimen. Kesesuaian hasil korelasi dengan hasil eksperimen didasarkan nilai root mean square deviation (RMSD). Berdasarkan hasil penelitian, persamaan model UNIQUAC memberikan nilai RMSD yang lebih kecil dari persamaan NRTL. RMSD dari model UNIQUAC sebesar 0.417% sedangkan dari NRTL sebesar 0.502%.
=================================================================================================
Liquid-liquid equilibrium (LLE) data of quaternary system eugenol + β-caryophyllene + 1-propanol + water were measured at temperatures 303.15, 313.15, and 323.15 K at atmospheric pressure. Equilibrium mixtures of eugenol + β-caryophyllene + 1-propanol + water were stirred intensely in a water jacket thermostat equilibrium cell at constant temperatures. The system was stirred for 4 hours and settled at least 20 hours to ensure that the equilibrium was reached. The sample mixtures were analyzed by a gas chromatograph to obtain the compositions of each component. All the measured data were correlated using NRTL and UNIQUAC model. The experimental results were compared with values correlated by NRTL and UNIQUAC model based on root mean square deviation (RMSD). Based on RMSD, UNIQUAC model gave smaller RMSD compared to NRTL. The RMSD of UNIQUAC and NRTL model was 0.417% and 0.502%.
