Abstract
Pemisahan asam asetat dari crude tidak dapat dilakukan secara optimal menggunakan distilasi sederhana karena nilai relative volatility yang rendah serta titik didih komponen yang berdekatan. Oleh karena itu, distilasi ekstraktif menjadi metode yang lebih efektif, dengan bantuan entrainer untuk meningkatkan efisiensi pemisahan. Deep Eutectic Solvents (DES) seperti choline chloride–diethylene glycol 1:3 (CC-DEG 1:3), choline chloride–triethylene glycol 1:3 (CC-TEG 1:3), serta ionic liquids [EMIM]BF₄ dan [EMIM]ESO₄ digunakan dalam proyek akhir ini karena interaksinya yang baik dengan asam asetat dan air, serta unggul sebagai green solvent. Proyek akhir ini mencakup pengukuran data Vapour–Liquid Equilibrium (VLE) untuk sistem biner air + asam asetat, dan sistem terner air + asam asetat + entrainer ([EMIM]BF₄, [EMIM]ESO₄, CC-DEG 1:3, dan CC-TEG 1:3) pada tekanan atmosfer (101,3 kPa) menggunakan alat ebulliometer yang telah divalidasi.

The separation of acetic acid from crude cannot be carried out optimally using simple distillation due to the low relative volatility and the close boiling points of the components.
Therefore, extractive distillation becomes a more effective method with the aid of entrainers to enhance the separation efficiency. Deep Eutectic Solvents (DES) such as choline chloride
diethylene glycol 1:3 (CC-DEG 1:3), choline chloride–triethylene glycol 1:3 (CC-TEG 1:3), as
well as ionic liquids [EMIM]BF₄ and [EMIM]ESO₄ were used in this study due to their good
interactions with acetic acid and water, and their superiority as green solvents. This final project includes the measurement of Vapour–Liquid Equilibrium (VLE) data for the binary system of acetic acid + water and the ternary system of water + acetic acid + entrainer ([EMIM]BF₄,
[EMIM]ESO₄, CC-DEG 1:3, and CC-TEG 1:3) at atmospheric pressure (101.3 kPa) using a validated ebulliometer.
