Some transition metal chlorides, CrCl3.6H2O, FeClO,CoCl2.6H2O, NiCl2.6H2O and CuCl2.2HO were investigated spectroscopically in the newly prepared choline chloride/ tartaric acid ionic liquid at room temperature.
This work involves synthesis of different five, six and seven member heterocyclic ring utilizing 2-aminopyridine as a starting material.This work is divided into four different parts:
Part One :
This part involved the synthesis of 3-biphenyl-4-ylimidazo[1,2-a] pyridine[1], 3-phenylimidazo[1,2-a]pyridine [2], imidazo[1,2-a]pyridine-3(2H)-one [3], 2H-pyrido[1,2-a]pyridine-2,4-(3H)-dione [4], N,N'-1,4-
The oxidation-reduction behavior of the newly prepared choline chloride/d-tartaric acid ionic liquid was studied by electrolysis at 25°C to 95°C with applied voltages of 0.5 to 5 volts. This ionic liquid was found stable up to 45°C and 5 volts as only showed small changes in current density. But, at 65°C the liquid showed noticeable unstable behavior particularly at or above 2.5 volt, which increased at higher temperature with increase conducting too.
