Synthesis and Study of Heteronuclear Citrates

Journal of Chemistry and Chemical Engineering 2014年第4期8卷 385-389页

作者： Nani Bldzlna Zhorzhohani Iamze Alim Beshkenadze Maia Avtandil Gogaladze Givi Tengiz Begheluri Petre Melikishvili Institute of Physical and Organic Chemistry Ivane Javakhishvili Tbilisi State University Tbilisi 0186 Georgia

Terms of synthesis were determined for creation of new generation premixes and for their testing in experiments. Heteronuclear chelate citrates of general formula： ***2O （where, M^I = Zn, Co, Fe, Mn, Cu; MH = Mn, Zn, Co, Cu; n = 0/4） were synthesized. Identity and composition of synthesized compounds were defined by microelemental analysis, determination of melting temperature and X-ray diffraction analysis. X-ray diffraction method was used also to define crystallinity of the compounds and their citric acid （H4L） component. X-ray amorphous and iso-structural orders were also revealed.

关键词： Bio-metals chelate compounds microelemental analysis X-ray diffraction analysis.

Journal of Chemistry and Chemical Engineering 2015年第1期9卷 56-60页

作者： lamze Beshkenadze Petre Melikishvili Institute of Physical and Organic Chemistry Laboratory of Problems of Agrarian Chemistry lvaneJavakhishvili Tbilisi State University Tbilisi 0186 Georgia Tbilisi State Medical University Tbilisi 0160 Georgia

Terms of synthesis were defined for the creation of new generation chelate fertilizers and for their experimental testing. Glutamine acid and citric acid containing chelate citrates of the general formulae ***＇nHO were synthesized, where, M = Mn, Zn, Fe, Co, Cu; n = 0; 1; 1.5; gl-glutamine acid; HL-citric acid anion. Identity and composition of synthesized compounds were determined by microelemental analysis, melting temperature and X-ray diffraction analysis. X-ray diffraction analysis of the compounds and glutamine acid and citric acid （H4L） was used to determine their crystalline structure and roentgen-amorphous and iso-structural orders. Their solubility was studied in various solvents.

关键词： Fertilizer chelate compounds melting microelemental analysis X-ray diffraction study.
