The IR spectrum of copper caprylate exhibits only one absorption band at about 1580 cm-1 which has been assigned to the binuclear configuration of copper soaps. The magnetic and spectroscopic studies confirm that the binuclear structure of copper caprylate persists in solutions. The absorption band near 375 mµ reveals the presence of coppercopper linkage and thus establishes the binuclear configuration of copper soaps in mixed solvents. The behaviour of copper soap and copper salt solutions is quite different and the absorption maxima are observed at different wavelengths.

Introduction:Biologically potent compounds are one of the most important classes of materials for the upcoming generations. Increasing number of microbial infectious diseases and resistant pathogens create a demand and urgency to develop novel, potent, safe and improved variety of antimicrobial agents. This initiates a task for current chemistry to synthesize compounds that show promising activity as therapeutic agents with lower toxicity. Therefore, a substantial research is needed for their discovery and improvement. Chemistry of present era aims to build a pollution free environment. For the same, it targets to create some alternativeswhich are eco-friendly and nature loving. Present research work is a step towards achieving such alternatives.Method:For this the metallic soaps of copper (derived from common edible oils) were synthesized. The synthesized copper soaps have been confirmed by elemental analysis, UV, and IR spectroscopic technique. The fungicidal activities of copper soaps derived from soyabean, sesame oils have been evaluated by testing against Alternaria alternate and Aspergillus niger by P.D.A. technique.Result:The fungi toxicity results indicate that the strain of fungal species are susceptible towards these soaps and suggests that with the increase in concentration of copper soap it may increase further. The transition metallic soaps showed good antifungal activity because chelation increases the anti-microbial potency.

Abstract A new method is described for the determination of serum lipase using olive oil as substrate, and photometric, copper soap analysis for the measurement of fatty acids formed. The great sensitivity of this technic for measurement of the fatty acids permits a 30-min. incubation time and the use of 0.1 ml. serum. The reaction is zero order for this time period. Other aspects of the enzyme kinetics were studied and the normal values determined.

1. Under the conditions of the tests cotton and hemp nets became rotten in Aquarium tank water in two months or less in summer, in 4½–5½ months in winter.2. A mixed copper soap, containing oleate, stearate, and palmitate, is as good, probably rather better, than is copper oleate as a net preservative.3. “Cuprinol,” a petroleum acid copper soap, is better than the fatty acid soaps, both in fresh and in salt water. It is more than three times as expensive, however.
