20.500.12556/RUL-160773 Kromove spojine s pirazinojsko kislino Chromium compounds with pyrazinoic acid Izvedli smo več reakcij med kromovim kloridom heksahidratom in pirazinojsko kislino v različnih topilih ali mešanicah le teh. V nekaterih primerih smo v reakcijsko zmes dodali še koncentrirano HCl. Reakcije so potekale pri sobni temperaturi ali na oljni kopeli pri temperaturi 60 °C. Nastali so temno zeleni kristali dveh koordinacijskih spojin [CrCl$_2$(pyza)(pyzaH)]·2H$_2$O in [Cr(pyza)$_3$]·nH$_2$O. Vse nastale produkte smo analizirali z IR spektroskopijo. Za dodatno potrditev sestave nastalih produktov smo uporabili še CHN analizo, termično analizo in rentgensko praškovno difrakcijo. Several reactions between chromium chloride hexahydrate and pyrazinoic acid were carried out in various solvents or their mixtures. In some cases, concentrated HCl was added to the reaction mixture. The reactions were conducted at room temperature or in an oil bath at 60 °C. Dark green crystals of two coordination compounds, [CrCl$_2$(pyza)(pyzaH)]·2H$_2$O and [Cr(pyza)$_3$]·nH$_2$O, were formed. All resulting products were analyzed by IR spectroscopy. To further confirm the composition of the products, CHN analysis, thermal analysis, and powder X-ray diffraction were also employed. koordinacijske spojine krom pirazinojska kislina chromium coordination compounds pyrazinoic acid true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-09-04 12:05:01 2024-09-04 12:05:23 2025-08-08 13:20:35 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 24243 211027203 Granda_Tjasa_-_Kromove_spojine_s_pirazinojsko_kislino.pdf Granda_Tjasa_-_Kromove_spojine_s_pirazinojsko_kislino.pdf 1 1D4F7E51E60E29761EC1A945024C37C6 eb6aba0621be54237f773b2d8f79a0187b81ac762394ad2f414c367ea82baba2 33bfd47d-6aa5-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=189552 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
