Synthesis and Electrical Conducting Behaviour of Resin Derived from 2, 6 -Diaminopyridine and Terphthalic Acid

Abstract

The resin DAPT was derived by condensing 2, 6-diaminopyridine (0.1 M) and terphthalic acid (0.1 M) in presence of DCC (Dicyclohexylcarbodiimide). The materials were characterized by using elemental analysis, 1 H NMR, 13 C NMR, FT-IR and UV-Vis spectra. The molecular weight of resin was determined by non aqueous conductometric titration. In the present paper, electrical conductivity properties of the resin DAPT was studied over a wide range of temperatures. The conductivity of DAPT was found to be in the range 0.1379 to 0.1583 µS cm -1 for temperature range 333-423 K. The activation energy of conduction for DAPT was found to be 0.7692 kJmol -1 .

Stabilization of Tetrachloride with Mn (II) and Co (II)Complexes and 4-Tert-Butylpyridinium Organic Cation: Elaboration of the Structure and Hirshfeld Surface, Optical, Spectroscopic and Thermal Analyses

“…It can be seen that most of the organic cations do not give rise to bands in the visible domain [59][60][61][62]. The LMCT phenomenon (ligand-to-metal charge transfer) between the chloride atom Cl and metal atom Co can be observed in two bands located at 423 and 469 nm [63][64][65][66][67][68][69]. The bands located at 542, 558 and 576 nm are intended for d-d electronic transitions, showing that the geometry of the cobalt atom contain stetrahedral [CoCl 4 ] 2− ( 4 A 2 (F)→ 4 T 2 (F), 4 A 2 (F)→ 4 T 1 (F) and 4 A 2 (F)→ 4 T 1 (P), which are generally attributed to compounds based on cobalt Co (II) [70][71][72].…”

Synthesis, Characterization and Ion-Exchange Properties of Terpolymer Resin-II Derived from p-Hydroxybenzaldehyde, Thiourea and Ethylene Glycol

“…A strong peak appeared at 1200 cm -1 was due to C=S stretching vibration. The presence [19][20] of peak at 831 cm -1 was due to the -CH 2 -(wagging). IR spectrum data of HBTE-II terpolymer is tabulated in Table 3.…”

“…Chem Sci Trans., 2014, 3(1), [19][20][21][22][23][24][25][26][27][28] Azarudeen et al 5 synthesized phthalic acid-urea-formaldehyde terpolymer resin and proved to be a selective chelation ion-exchange terpolymer for metals. A batch equilibrium method was employed to study the selectivity and sorption capacity of the resin towards certain divalent metal ions such as Pb 2+ …”
