Abstract

In the recent years, the synthesis of transition metals naphtenates became very important because of large application possibilities. Those types of inorganic synthesis become a reason for discovery and the study of new coordination compounds. The experiments are designed to make complex compounds of eyclic carbon acid and to study their differences from simple carboxylates. By using of naphthanic acid (cycloheksane carboxylic acid) and sodium hydroxide, sodium naphthenate is produced. Then applying substation reaction, cobalt naphthenate is synthesized. The optimal yields for cobalt naphthenate is obtained by a two step reaction. The physical and chemical properties and structural characteristics for acid and naphthenate are obtained by applying IR, NMR and termogravimetric analysis. In this study antimicrobial activity of sodium naphthenate was also investigated on Gram-positive cocci (Staphylococcus aureus), Gram-negative bacilli (Escherichia coli) and yeast (Candida albicans).
