Abstract

DiEtil Eter banyak digunakan sebagai bahan pelarut untuk reaksi organik dan pemisahan senyawa organik dari sumber alamnya, sebagai bahan bakar. DiEtil Eter umumnya diproduksi dengan proses dehidrasi etanol dengan katalis asam sulfat pada suhu 125⁰C – 140⁰C (proses barbet). Penelitian ini bertujuan untuk memperoleh kondisi optimum pada pembuatan dietil eter dengan katalis asam sulfat dan proses reaktif distilasi. Variabel yang dioptimasi adalah konsentrasi asam sulfat awal dan perbandingan mol reaktan etanol dengan asam sulfat. Proses optimasi menggunakan metode respon permukaan dan pengolahan data dengan perangkat lunak Statistica^(R.⁾ Proses pembuatan dietil eter dilakukan pada volume 700 ml, waktu 100 menit dan suhu operasi 125-130⁰ C. Hasil penelitian menunjukkan bahwa model matematika yang diperoleh hubungan konversi etanol dengan perbandingan mol reaktan etanol dengan asam sulfat dan konsentrasi awal asam sulfat adalah . Konversi etanol optimum sebesar 31,83 % pada kondisi operasi perbandingan mol reaktan etanol dengan asam sulfat 1 : 1,30 dan konsentrasi awal asam sulfat 10,98 M.

Authors publishing in BCREC journals have wide rights to use their works for teaching and scholarly purposes without needing to seek permission, including, but not limited to:

use for classroom teaching by the Author or the Author's institution and presentation at a meeting or conference and distributing copies to attendees;
use for internal training by the author's company;
distribution to colleagues for their research use;
use in a subsequent compilation of the author's works;
inclusion in a thesis or dissertation;
