Abstract

Ionske su tekućine kvaterne soli koje predstavljaju zelenu zamjenu za štetna hlapljiva organska otapala. Cilj ovoga rada bio je priprava trisupstituiranih imidazolijevih ionskih tekućina reakcijama kvaternizacije 1,2-dimetilimidazola s 1-bromheptanom te reakcijama izmjene aniona s različitim solima. Također, ispitan je utjecaj aktivacije mikrovalovima odnosno ultrazvukom na reakciju kvaternizacije. Strukture pripravljenih trisupstituiranih imidazolijevih ionskih tekućina određene su pomoću podataka dobivenih 1Hi 13C-nuklearno-magnetskom rezonancijom.

Abstract (english)

Ionic liquids are quaternary salts that are green replacement for harmful volatile organic solvents. The aim of this study was to prepare trisubstituted imidazolium ionic liquids by quaternization of 1,2-dimethylimidazole with 1-bromoheptane followed by anion exchange reactions with various salts. The effect of activation by microwaves or ultrasound onto quaternization reaction was examined, too. Structures of the trisubstituted imidazolium ionic liquids prepared were determined by using data obtained by 1H-and 13C-nuclear magnetic resonance.
