Abstract
Penelitian ini bertujuan untuk mendapatkan data kesetimbangan cair-cair sistem terner β-Caryophyllene + Ethanol + Air dan β-Caryophyllene + 1-Oktanol + Air yang diukur pada suhu 303.15 K. Peralatan yang digunakan adalah equilibrium cell 40 mL yang dilengkapi dengan jaket pemanas. Jaket pemanas dialiri air yang disirkulasi melalui waterbath untuk menjaga suhu kesetimbangan. Data kesetimbangan diperoleh dengan mengaduk campuran komponen murni tersebut selama 4 jam dan kemudian didiamkan selama 20 jam agar kondisi kesetimbangan tercapai. Masing-masing sampel diambil secara terpisah untuk dianalisa komposisinya sebagai komposisi kesetimbangan menggunakan Gas Chromatography dan metode titrasi reduksi-oksidasi. Dari eksperimen pada kedua sistem tersebut diperoleh diagram terner Treyball tipe I unsuk sistem β-Caryophyllene + Ethanol + Air dan Treyball tipe II untuk sistem β-Caryophyllene + 1-Oktanol + Air dari area dua fase. Data yang diperoleh dari masing-masing sistem dikorelasikan dengan persamaan NRTL dan UNIQUAC yang memberikan RMSD dari komposisi kesetimbangan masing-masing sebesar 1.1% dan 2.0% untuk sistem terner β-Caryophyllene + Ethanol + Air dan RMSD 1.1% dan 4.3% untuk sistem terner β-Caryophyllene + 1-Oktanol + Air. Berdasarkan kapabilitas antara Ethanol dan 1-Oktanol, didapatkan hasil bahwa pelarut yang lebih baik digunakan untuk melarutkan β-Caryophyllene dari campuran β-Caryophyllene dan air adalah Ethanol.
=================================================================
The liquid - liquid equilibrium (LLE) data of ternary β-C aryophyllene + Ethanol + Water and β-Caryophyllene + 1-Octanol + Water was measured at temperature of 303.15 K. The equilibrium cell with 40 mL volume
equipped with stirrer and
water jacket thermostat connected with water bath to maintain equilibrium cell at constant temperature.
The experiment was started by adding
certain compositions of ternary mixture into
equilibrium cell and stirred by magnetic stirrer for 4 hours, then it was allowed to settle
for 20 hours in order to be completely
separated into organic and aqueous phases.
The compositions of each phase were analyzed using Gas Chromatography and reduction-oxidation titration. β-Caryophyllene + Ethanol + Water system exhibited Treyball type I phase behavior, and β-Caryophyllene + 1-Octanol + Water system exhibited Treyball type II phase behavior.
The experimental data were correlated using NRTL and UNIQUAC
models giving RMSD between experimental and calculated compositions of 1.1% and 2.0% respectively,
for the system of β-Caryophyllene + Ethanol +
Water and 1.1% and 4.3% respectively, for the system of β-Caryophyllene + 1-Octanol + Water. Based on the solvent’s capability between Ethanol and 1-Octanol, the solvent which gives the better result to recover β-Caryophyllene from the mixture of β-Caryophyllene and water is Ethanol.
