Seven quaternary N-morpholinium chlorides were synthesized by treating N-alkylmorpholine with chlorohydrocarbon. 1H NMR, 13C NMR spectroscopy and elemental analysis were used to characterize the synthesized products. Thermal properties of the new compounds were studied using TG/DTA. Some of the synthesized compounds seem to be suitable for ionic liquid applications because melting points were observed for most of them. And the good thermal stability of these compounds enables their potential use for example as phase-transfer catalysts and electrolytes. The results show N-methyl-N-butylmorpholinium chloride has dissolving capacity to the polyacrylonitrile.

Key words: ionic liquid, N-dialkylmorpholinium salt, thermal analysis, polyacrylonitrile
