Abstract
This work deals with surfactant-free microemulsions (SFME) and is composed of two parts. In the first part these kind of ternary systems were investigated as a possible alternative for toxic extraction solvents that are still in use. In the second part pre-structuring of hydrotropes in water was studied, and its influence on the solubilisation of a third, hydrophobic component. Solvent extraction is widely used as a separation method. With the evolution of green chemistry new solvents are... More required with properties such as low toxicity and easy separation. SFMEs are considered as possible alternatives due to their better wetting properties and their possibility of solubilisation of hydrophobic components. Such solubilisation properties depend on the formation of supramolecular aggregates that typically occur in such systems. Three systems were investigated for this purpose: oleic acid/solketal/H 2 O, glycerol triacetate/EtOH/H 2 O and triethyl citrate/EtOH/H 2 O. All systems showed pronounced mesoscale structuring near the phase separation border proved by DLS measurements. Ternary system oleic acid/solketal/H 2 O was a “proof of principle system” of a cleavable SFME suitable for green extraction. Recently, it was established that structuring of binary mixtures of short chain alcohols/H 2 O have a significant influence on the solubilisation of hydrophobic compounds such as benzyl alcohol and limonene. Second part of the work was focused on the study of more versatile hydrotropes such as dimethyl sulfoxide (DMSO), dimethylformamide (DMF), acetonitrile (ACN), dioxane, ethanol (EtOH), tert-butyl alcohol (TBA), γ-valerolactone (GVL) and tetrahydrofuran (THF). DLS and conductivity measurements were carried out to demonstrate the presence of structures in the binary and ternary mixtures. surfactant-free Less
Abstract (croatian)
Ovaj rad se bavi mikroemulzijama bez prisutnosti surfaktanata te se sastoji se od 2 dijela. U prvom dijelu, ove vrste ternarnih sustava istraživane su kao zamjena za toksična ekstrakcijska otapala koja su još u upotrebi. U drugom dijelu proučavana je strukturiranost hidrotropa u vodi u pre-Ouzo području i njen utjecaj na otapanje hidrofobne komponente. Ekstrakcija je često korištena metoda odvajanja. Sve veći razvoj zelene kemije utjecao je na potražnju novih otapala ... More koja ispunjavaju svojstva kao što su niska toksičnost i laka separacija. Smatra se da se mikroemulzije bez prisutnosti surfaktanata mogu koristiti kao zamjena za komercijalno dostupna ekstrakcijska otapala zbog boljeg svojstva kvašenja i mogućnosti otapanja hidrofobnih komponenata. Takva svojstva otapanja uvelike ovise o stvaranju supramolekularnih agregata koji se u pravilu odvijaju u ovim sustavima. U ovom radu ispitivana su tri sustava: oleinska kiselina/solketal/H 2 O, glicerol- triacetat/EtOH/H 2 O i trietil-citrat/EtOH/H 2 O. Svi sustavi pokazali su strukturiranost blizu granice faza, što je i dokazano DLS mjerenjima. Ternarni sustav oleinska kiselina/solketal/ H 2 O najviše se istaknuo kao sustav bez prisutnosti surfaktanata prikladan za zelenu ekstrakciju. Nedavno je utvrđeno da strukturiranost binarnih sustava kratkolančanih alkohola/H 2 O ima veliki utjecaj na otapanje hidrofobnih komponenti poput benzil alkohola i limonena. Drugi dio rada usredotočen je na istraživanje različitih hidrotropa poput dimetil sufoksida (DMSO), dimetilformamida (DMF), acetonitrila (ACN), dioksana, etanola (EtOH), tert-butil alkohola (TBA), γ- valerolaktona (GVL) i tetrahidrofurana (THF). DLS i konduktometrijska mjerenja provedena su da se dokaže prisutnost struktura u binarnim i ternarnim sustavima. Less
