THE CONCLUSION

1. Fragments of succinic acid hexamethylene diamine - ^ To - dijantarnaja (GMDDJAK) and ethylene diamine-n, №-dijantarnaja (EDDJAK) acids are synthesised kompleksony, containing in quality of acid substituents.

2. The rn-potentiometric titration method defines concentration and thermodynamic constants of acid dissociation GMDDJAK. It is confirmed, that investigated kompleksony in water solution have betainovuju structure.

3. According to rn-potentiometric measurements with use of methods of mathematical modelling composition and stability of complexes Ga3+и B (OH) 3 with EDDJAK, and also Mg2 +, Ca2 +, Sr2 +, Ba2 +, Al3 +, Ga3+и B (OH) 3 with GMDDJAK are positioned.

4. It is positioned, that stability of complexes with metals III-А of a subgroup increases with increase in radiuses of ions among Al3 + - Ga3 +, that speaks increase of polarising action of the generated cover of d-electrons at gallium. As a result of it, there is a deformation of electronic shells of the central atom of cation and a ligand, result ining to their interpenetration, as causes hardening of communications.

5. Among shchelochno-ground elements with growth of ionic radius of metals depressing of stability of complexes lg Km ^> lg KCaL> lg Ksγl> lg KβaL is observed. This sequence sometimes named a natural number of stability, is caused by energy of stabilisation of a crystal field.

6. Laws in change of stability of complexes of elements II-А and III-А subgroups depending on length of the methylene chain between atoms of nitrogen studied kompleksonov are positioned. With growth of quantity of the methylene groups in them easing of communication of ligands with studied elements that speaks bajerovskim and prelogovskim pressure is observed.

7. Complexes of elements II-А and III-А subgroups with studied kompleksonami are evolved in a solid kind.

8. The method of atomic absorption spectrometry positions composition evolved kompleksonatov NaMc'L.

9. Method IK of spectroscopy studies a structure of solid complexes of elements II-А and III-А subgroups. It is shown, that in complexes of aluminium and gallium with EDDJAK and GMDDJAK there are as koordinirovannye, and free carboxyl groups. It is positioned, that at formation of complexes SHCHZM with GMDDJAK betainovaja the structure kompleksona is not broken, that is the atom of nitrogen is not co-ordinated by ions of these metals. In complexes of boron and metals III-А of a subgroup with GMDDJAK existence of communication of metals with nitrogen is proved.

10. The thermo-grav method positions number of molecules intra-and vneshnesfernoj waters in the evolved solid complexes.

11. By results of the made researches the assumption is made, that GMDDJAK in complexes with SHCHZM displays dentatnost equal to two, and dentatnost EDDJAK and GMDDJAK in complexes with aluminium is equal to four, and with
Gallium of five. Prospective constitutional formulas investigated kompleksonatov are constructed.

12. Practical application geksametilendiamindijantarnoj and etilendiamindijantarnoj acids as highly effective retardants of hydration of the calcium knitting is shown. KPJAK are used in the patented compositions for dissolution of nakipno-corrosion depositions. Studied kompleksony are a good pollution-free vehicle of trace elements in plants and a live organism. In particular, EDDJAK it is applied by us to creation of a mineral complex on the basis of an egg shell with the raised biological value and bioavailability.
