20.500.12556/RUL-144438 Hidroksipiridinijeve soli – ionske tekočine Hydroxypiridinium Salts – Ionic Liquids V diplomskem delu so opisane sinteze hidroksipiridinijevih soli. Uporabljene izhodne spojine so piridin-2-on (2hpy), 3-hidroksipiridin (3hpy) ali 2-amino-3-hidroksipiridin (2ahpy) in klorovodikova kislina. Pripravili smo dve znani spojini: 2-hidroksipiridinijev klorid in 2-hidroksipiridinijev klorid hidrat ter nove spojine: 3-hidroksipiridijev klorid, 2-amino-3-hidroksipiridinijev klorid in njuna hidrata. Pri vseh sintezah je potekala kristalizacija na zraku, iz raztopin so se izločili kristali. Sestavo in strukturo produktov smo določili z infrardečo spektroskopijo, rentgensko strukturno analizo in CHN analizo. Z rentgensko strukturno analizo smo določili zgradbo 2-amino-3-hidroksipiridinijevega klorid hidrata. S termično analizo smo določili temperaturo tališča pripravljenih soli in mehanizem razpada. Med izoliranimi solmi je ionska tekočina le 2-hidroksipiridinijev klorid. The diploma work describes the synthesis of hydroxypiridinium salts. The starting compounds used are pyridin-2-one (2hpy), 3-hydroxypyridine (3hpy) or 2-amino-3-hydroxypyridine (2ahpy) and hydrochloric acid. Two known compounds have been prepared: 2-hydroxypyridinium chloride and 2-hydroxypyridinium chloride hydrate, and new compounds: 3-hydroxypyridinium chloride, 2-amino-3-hydroxypyridinium chloride and their hydrates. All were crystallized in the air and crystals were extracted from the solutions. The composition and structure of the crystals were determined by infrared spectroscopy, X-ray powder analysis and CHN analysis. X-ray structural analysis was used to determine the structure of 2-amino-3-hydroxypyridinium chloride hydrate. Thermal analysis was used to determine the melting point of the prepared salts and the mechanism of decomposition. Among the isolated salts, only 2-hydroxypyridinium chloride is an ionic liquid. piridin-2-on 3-hidroksipiridin 2-amino-3-hidroksipiridin hidroksipiridinijeve soli ionske tekočine. pyridin-2-one 3-hydroxypyridine 2-amino-3-hydroxypyridine hydroxypiridinium salts ionic liquids. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-02-22 08:40:00 2023-02-22 08:40:02 2023-02-23 13:31:59 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 20701 142862339 Volt_Karin_-_Hidroksipiridinijeve_soli_–_ionske_tekocine.pdf Volt_Karin_-_Hidroksipiridinijeve_soli_–_ionske_tekocine.pdf 1 F41485B39BBF4C2455292B0FD1EB746A b43496b697cb20c0cdb6abde1bd697562b1914b0c56dc0c8217201dea790fa9f c6296848-b283-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=166748 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
