Sinteza cinkovih kompleksov z dipikolinsko kislino

Žveglič, Sanja (avtor), Perdih, Franc (mentor)

V okviru diplomske naloge je bila moja naloga sintetizirati koordinacijsko spojino [Zn(dipic)]. Pri sintezi sem uporabila različne reaktante in dve različni topili, in sicer vodo in metanol. Izvedla sem osem sintez s podvojenimi masami glede na osnovno recepturo. Glavni reaktant vsake sinteze je bila dipikolinska kislina. Kot vir cinka sem uporabila cinkov klorid in cinkov acetat. Kot bazi sem uporabila natrijev hidroksid in 4-dimetilaminopiridin. Vse pridobljene produkte, ki so izkristalizirali v viali, in produkte, ki sem jih dobila z filtracijo, sem posušila oziroma pustila izhlapevati in pripravila za nadaljnjo analizo. Sledila je rentgenska praškovna analiza, ki je bila opravljena na Kemijskem inštitutu v Ljubljani. Na fakulteti pa sem opravila še IR spektroskopijo. Na podlagi rezultatov rentgenske praškovne analize sem ugotovila, da mi je uspelo sintetizirati spojino, katere vrhovi so se dobro ujemali z vrhovi na difraktogramu za [Zn(dipic)].

Izvleček

As part of my thesis, my task was to synthesise a coordination compound [Zn(dipic)]. I used different reactants and two different solvents, water and methanol. I made 8 syntheses in which I doubled the masses that were written in the basic recipe. The main reactant in each synthesis was dipicolinic acid. I used zinc chloride and zinc acetate as sources of zinc. I used sodium hydroxide and 4-dimethylaminopyridine as bases. All the products obtained, which crystallised in the vial and those obtained by filtration, were dried or allowed to evaporate and prepared for further analysis. This was followed by X-ray powder analysis, which was carried out at the Institute of Chemistry in Ljubljana. I also did IR spectroscopy at university. Based on the results of the X-ray powder analysis, I found that I had managed to synthesise a compound whose peaks closely matched the peaks in the diffractogram for [Zn(dipic)].
