20.500.12556/RUL-177947 Bakrovi karboksilati pri zaščiti lesa; dolžina karboksilatne verige in dodatni ligandi Copper carboxylates in wood preservation; carboxylate chain length and additional ligands Izvedla sem sinteze v različnih sistemih z bakrovimi(2+) ioni in s tremi vrstami anionskih alifatskih karboksilatov (propanoat L$^{C3}$, heksanoat L$^{C6}$ in nonanoat L$^{C9}$), ki se razlikujejo po dolžini verige. Vsem sem dodala tudi eno piridinsko spojino, nikotinamid L$^1$, 3-hidroksipiridin L$^2$, 2-hidroksipiridin L$^3$ in 2-aminopiridin L$^4$. Vse te sinteze so bile opravljene pri treh različnih koncentracijah v vodi. Uporabila sem IR spektroskopijo za analizo produktov. Največ trdne snovi z najboljšimi izkoristki se je izločilo pri uporabi L$^2$. Spojina [Cu(L$^{C6}$)$_2$(L$^2$)$_2$]n je že bila opisana. Pri L$^3$ se je trdni produkt s tem piridinskim ligandom izločil le pri propanoatu L$^{C3}$ pri najvišji uporabljeni koncentraciji. Uporaba L$^1$ in L$^4$ vodi do produktov s temi molekulami, ki pa se spreminjajo glede na koncentracijo in dolžino verige. Za nanos, ki bi se najmanj spreminjal ob prisotnosti dodatne vode, se najbolje izkaže nonanoatni anion L$^{C9}$ ob L$^2$. Syntheses in several systems with copper(2+) ions and three types of aliphatic carboxylate anions (propanoate L$^{C3}$, hexanoate L$^{C6}$, and nonanoate L$^{C9}$), differing in chain length, were carried out. One pyridine-type compound was also added to each of them, namely nicotinamide L$^1$, 3-hydroxypyridine L$^2$, 2-hydroxypyridine L$^3$, and 2-aminopyridine L$^4$. All these syntheses were carried out at three different aqueous concentrations. IR spectroscopy was used to analyze the solid products. The best yields were obtained using L$^2$. One of these compounds with formula [Cu(L$^{C6}$)$_2$(L$^2$)$_2$]n has already been described. The solid product with L$^3$ pyridine ligand was obtained only with propanoate L$^{C3}$ at the highest concentration applied. On the other hand, the remaining L$^1$ and L$^4$ molecules are also found within the solid products, however, their compositions vary depending on concentration and the aliphatic chain length. An application of these copper compounds for coating at a presence of additional water, the nonanoate anion L$^{C9}$ in combination with L$^{2}$ seems to be the optimal solution. bakrovi karboksilati piridinski ligandi bakrov acetat dihidrat koordinacijske spojine copper carboxylates pyridine ligands copper acetate dihydrate coordination compounds true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-01-14 11:45:03 2026-01-14 11:45:10 2026-01-30 09:31:16 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 25560 266751747 Glojek_Neza_-_Bakrovi_karboksilati_pri_zasciti_lesa;_dolzina_karboksilatne_verige_in_dodatni_lig.pdf Glojek_Neza_-_Bakrovi_karboksilati_pri_zasciti_lesa;_dolzina_karboksilatne_verige_in_dodatni_lig.pdf 1 610A8E9E8124C859A0DA6497E3571E5B f2e9f1b25ea59c266ce9491d3dfa06d9eec35d4c0f76538bd1bf7b5f861108fb 100750e8-f136-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225394 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
