Abstract
Penelitian ini bertujuan untuk mendapatkan data kesetimbangan cair-cair sistem quaterner Eugenol + β-Caryophyllene + 1-Butanol + H2O diukur pada temperatur 303,15 dan 323,15 K. Peralatan yang digunakan adalah equilibrium cell yang dilengkapi dengan jaket pemanas. Jaket pemanas dialiri air yang disirkulasikan melalui waterbath untuk menjaga suhu kesetimbangan. Data kesetimbangan diperoleh dengan mengaduk campupran komponen murni tersebut selama 4 jam dan kemudian didiamkan selama 20 jam agar kondisi kesetimbangan tercapai. Masing-masing sampel diambil secara terpisah untuk dianalisis komposisinya sebagai komposisi kesetimbangan menggunakan Shimadzu Gas Chromatography 2010 Plus. Penelitian diulagi untuk komposisi awal yang berbeda agar diperoleh tie line atau model kurva yang terdistribusi secara merata pada rentang komposisi kesetimbangan. Data kesetimbangan yang diperoleh dikorelasikan dengan model persamaan NRTL dan UNIQUAC untuk kemudian dibandingkan dengan hasil eksperimen. Kesesuaian model dalam mengkorelasikan data didasarkan pada harga 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 0,855% sedangkan NRTL sebesar 1,425%; serta pelarut 1-Butanol dapat memisahkan Eugenol dengan β-Caryophyllene ditinjau dari selektivitas pelarut terhadap kedua komponen tersebut.
=========================================================
The liquid-liquid equilibrium (LLE) data of quaternary system of Eugenol + β-Caryophyllene + 1-Butanol + H2O were measured at temperatures of 303.15 and 323.15 K. Equilibrium mixtures of Eugenol + β-Caryophyllene + 1-Butanol + H2O were stirred intensely in water-jacketed thermostat equilibrium cell at certain constant temperatures. The system was stirred for 4 hours and settled at least 20 hours to ensure that the equilibrium has been reached. The sample mixtures were analyzed using a Gas Chromatograph to obtain the compositions of each components. All the measured data were correlated using NRTL and UNIQUAC models. The reliability of the models was tested by comparing the calculated equilibrium compositions with experimental data in terms of root mean square deviations (RMSD). Based on the average RMSD, the UNIQUAC model gave smaller RMSD value compared to the NRTL model. The RMSD value of UNIQUAC and NRTL model respectively were 0,855% and 1,425%; and 1-Butanol can separate Eugenol and β-Caryophyllene from its mixture reviewed from its selectivity towards those two components.
