Comparative Studies between Conventional Techniques and Green Chemistry to Synthesis of Novel Piperidinium Salts Ionic Liquids (PBSILs)

Abstract

Comparative studies between conventional technique, method (A) and green chemistry (microwave irradiation) , method (B) to synthesis of four novel unsymmetrical alkyl piperidinium salts ionic liquids (PBSILs) by the addition of alkyl halides (methyl or allyl) to piperidine  with yields more than (90%) in method (A) and less than (70%) in method (B) respectively with decrease reaction time. Theses novel organic salts are characterized by elemental analysis, ¹H NMR, FTIR and mass spectrometry.
