ABSTRACT

Solid-Liquid Equilibria data of binary system, such as imidacloprid (IMIP) + 2-nitroaminoimidazoline (NIM), 2-Nitriminoimidazolidine,1,1'-(2,5-pyridinediyl)bis- (NMP) + IMIP, 2-nitroaminoimidazoline + NMP, NMP + NIM + IMIP were determined by differential scanning calorimetry (DSC), and given corresponding phase diagrams, respectively. All of them are identified as eutectics type, the corresponding eutectic molar compositions (x_eu,1) are 0.4962, 0.4229 C0.5506, and temperatures (T_eu) are 402.41, 407.46 and 383.13 K, respectively, for IMIP(1) + NIM(2), NMP(1) + NIM(2), IMIP(1) + NMP(2). Furthermore, solid-liquid equilibrium data for the ternary system of NMP(1) + NIM(2) + IMIP(3) was also determined by DSC, T_eu is 373.77 K and x_eu is 0.3507. So it is significative to provide important engineering data for the separation and purification of imidacloprid.
