Synthesis and study of Arginin-containing copper and chrome chelates

Abstract

Synthesis conditions have been established and arginin (Arg)-containing copper and chrome chelate compounds with the following general formulas: CuArgn(CH3COO)2·mH2O and CrArgn(CH3COO)3·mH2O (where n =1÷3; m=2 or 4) have been synthesized. Synthesized chelates have been studied using a number of physical and chemical research methods. In particular, their composition has been established via trace element analysis, while the individuality has been identified through melting temperature measurement and diffractographic method. Through study of qualitative solubility in different solvents there has been established that chelates are highly soluble in water and poorly soluble in organic solvents. Using the conductometric research method there has been calculated a dissociation constant of chelate compounds-containing solutions. Based on the preliminary trial tests carried out in order to study the biological activity, there is expressed an opinion that entry of arginin-containing copper and chrome chelates into composition of combined feed premixes of egg-laying (oviparous) poultry has had a positive impact on egg-laying intensity and poultry survival rate. There is given an opinion on the expediency of basic test conduct in order to determine the optimum doses of arginin-containing copper and chrome chelate compounds for egg-laying birds.
