Abstract

Ionske se tekućine zbog svojih izvrsnih svojstava smatraju zelenim otapalima budućnosti. Primjenjuju se u brojnim područjima kemijske i farmaceutske industrije kao zamjena za štetna hlapljiva organska otapala. Cilj ovog rada bila je sinteza novih morfolinijevih ionskih tekućina reakcijama kvaternizacije osnovnih sirovina, N-metilmorfolina i N-etilmorfolina s 1-brompentanom, 1-bromheksanom i 1-bromheptanom korištenjem mikrovalnog zračenja, a provedena je i izmjena aniona produkata kvaternizacije s litijevim bis[(trifluormetil)sulfonil]imidom. Ukupno je sintetizirano dvanaest (12) novih, do sada neobjavljenih, soli čije su strukture određene pomoću podataka dobivenih 1H- i 13C-nuklearno-magnetskom rezonancijom.

Abstract (english)

Due to their excellent characteristics, ionic liquids are considered to be the green solvents of the future. They are included in numerous areas of chemical and pharmaceutical industry where they replace harmful volatile organic solvents. The final goal of this study was the synthesis of new morpholinium ionic liquids prepared by quaternization of N-methylmorpholine and N-ethylmorpholine as the basic raw materials with 1-bromopentane, 1-bromohexane and 1-bromoheptane by microwave irradiation. Anion exchange reactions followed in wich the products of quaternization reacted with lithium bis[(trifluoromethyl)- sulfonyl]imide. A total of twelve (12) novel, till now unpublished, salts were synthesized and their structures determined according to the data obtained by 1H- and 13C-nuclear magnetic resonance.
