Electrical Conductivity of Acetyl Acetonyl binylidene 5- Amino Salicylic Acid in Ethanol: Water Mixtures at Different Temperatures

The electrical conductivity of acetyl acetonyl binyledene 5amino salicylic acid has been measured in (ethanol: water) mixtures at different percentage and different temperatures (283.16oK 313.16o K). The results were analyzed by using Lee – Wheaton equation. The conductivity parameters, Λo (equivalent conductivity at infinite dilution, KA (association constant) and R (distance parameter between the ions) were calculated. From this study detail information about the conductivity parameters are interpreted Which have been effected by varying the temperatures. Thermodynamic parameters ∆ H, ∆G and ∆ S were also calculated. INTRODUCTION The measurement of electrolytic conductivities of aqueous solutions of electrolytes provides available method of studying the ionic interaction. Electrical Conductivity of Acetyl Acetonyl binylidene 5Amino Salicylic Acid ... 2 Comparison of the Fuoss 1975 (1) conductance equation with previous equations shows that the only one which is based on a model which rigorously permits the use of macroscopic dielectric constant D and viscosity η in the theoretical calculation of relaxation field and electophoresis. Lee and Wheaton describe (2,3,4) the derivation of the conductance equation based on a model identical to that suggested by Fuoss but using a new boundary condition to replace that used by Fuoss. Conductance measurements in binary mixed solvents have been widely used for the investigation of solute – solvent interactions in electrolytes solutions. Many electrolytes solutions in different percentage of solvents mixtures and different temperatures have been studied, Ansari and Islam (5) studied the conductivity and the ionic association of tetraalkylammonium halides in tert-butanol-water mixture at 25°C. Haruhiko, Tomako and Masayasu (6) studied the conductometry of ion association between tris (ethylenediamine) cobalt(III) ion and monovalent anions at temperatures from 0 to 50 °C. Tominic et.al (7) studied the conductometry of hydrobromic acid in 2propanol and water mixtures. Conductivity of (8) n-tetrabutylammonium tetraphenyl borate in 3pentanone in the temperature range from 283.15 oK to 329.15 oK studied by Tsierkezoz and Molinon. El-Dossoki (9) studied the dissociation of quinic acid and association constants of some quinateions in aqueous and in alcoholic−aqueous mixed solvents. In this work we have measured the electrical conductivity of acetyl acetonyl binyledene 5amino salicylic acid has been measured in (ethanol: water) mixtures at different percentage and different temperatures (283.16 oK 313.16oK). The conductivity parameters were calculated using Lee and Wheaton equation. EXPERIMENTAL Synthesis of acetyl acetonyl binylidine 5amino salicylic acid: This compound was prepared 10 By mixing 0.08 mole (8.0g) of acetyl acetone with 0.16 mole (24.48 g) of 5-amino salicylic acid. In 100 ml round bottom flask, mix the quantities of acetyl acetone and the amounts of 5-amino salicylic acid mentioned. Add to the mixture 150 ml of ethanol. The mixture was reflexed for 6 hours. The product was cooled in ice bath, following by washing the product with cold ethanol and dried.
