Abstract

Ionske tekućine su kvaterne soli koje predstavljaju značajan potencijal za industrijsku primjenu kao “zelena” zamjena za štetna hlapljiva organska otapala i anorganske katalizatore. Posebno se upotrebljavaju imidazolijeve ionske tekućine zbog njihovih jedinstvenih fizikalnih i kemijskih svojstava. Cilj ovog rada bila je sinteza bazičnih imidazolijevih ionskih tekućina. Kvaterne soli 1-metilimidazola s alil-bromidom, benzil-kloridom i pentil-bromidom te 1,2-dimetilimidazola s pentil-bromidom prevedene su u odgovarajuće hidrokside reakcijom s kalijevim hidroksidom odnosno ionsko-izmjenjivačkom smolom Amberlite IRN 78. Strukture novih, do sada neobjavljenih, spojeva [5]-[8] određene su pomoću podataka dobivenih 1H- i 13C- nuklearno-magnetskom rezonancijom.

Abstract (english)

Ionic liquids are quaternary salts, which have a high potential for industrial application as a "green" substitute for harmful volatile organic solvents, and inorganic catalysts. Especially used are imidazolium ionic liquids due to their unique physical and chemical properties. The aim of this work was the synthesis of basic imidazolium ionic liquids. Quaternary salts of 1-methylimidazole with allyl bromide, benzyl chloride and pentyl bromide as well as 1,2-dimethylimidazole with pentyl bromide were changed into the corresponding hydroxides by reaction with potassium hydroxide and ion-exchange resin Amberlite IRN 78. The structures of novel, so far, unpublished compounds [5] - [8] were determined by using data obtained from 1H-and 13C-nuclear magnetic resonance.
