Abstract

Separacija azeotropnih smjesa predstavlja izazov jer se komponente ne mogu separirati jednostavnom destilacijom. Provedba separacije azeotropne smjese zahtijeva korištenje velike količine energije i primjenu toksičnih otapala, što ima negativan utjecaj na okoliš. Alternativa toksičnim otapalima su niskotemperaturna eutektička otapala (eng. Deep Eutectic Solvent, DES) jer su ekološki prihvatljiva te su jednostavna i jeftina za pripravu. U ovom radu istražena je mogućnost separacije dvokomponentne azeotropne smjese 2-propanola i vode procesom ekstrakcijske destilacije, uz primjenu četiri različita otapala: glicerol, etilen-glikol te niskotemperaturno eutektičko otapalo (kolin klorid:glicerol (molni omjer 1:2) i
kolin klorid:etilen-glikol (molni omjer 1:2,5)).

Abstract (english)

Separation of azeotropic mixtures poses a challenge as their components cannot be easily separated by simple distillation. Separation of the azeotropic mixture requires the supply of large amounts of energy and harmful solvents, which harms the environment. An alternative to toxic solvents are deep eutectic solvents, they are environmentally friendly, simple and inexpensive to prepare. This paper explores the possibility of separating a binary azeotropic mixture of 2-propanol and water using extractive distillation, with the use of four different solvents: glycerol, ethylene glycol, and deep eutectic solvent choline chloride:glycerol (molar ratio 1:2) and deep eutectic solvent choline chloride:ethylene glycol (molar ratio 1:2,5).
