실험 절차

2,4 pentanedione (Acac) is degassed by a freeze/pump/thaw method on a Schlenk line over a bed of grade 4A molecular sieves and back filled with argon gas. In a nitrogen-filled drybox, 34.041 g of titanium(IV) n-butoxide (Acros; 0.100 moles) are placed into a 100 ml bottle, and 20.020 g of 2,4 pentanedione (0.200 moles; Aldrich) is then added dropwise and left to stir for 12 hours. In a fumehood, 31.750 g of barium hydroxide hydrate (0.101 moles; Aldrich) is added to a 500 ml volumetric flask. 200 ml of a 50:50 solution of 1-butanol/propanoic acid would then be added and stirred to form barium propanoate. The titanium solution [bis(acetylacetonato)/bis(butoxo)titanium] is then removed from the drybox and added to the volumetric flask containing the barium hydroxide solution. The round bottom flask is rinsed several times with 50:50 1-butanol:propanoic acid solution into the volumetric flask. A 50:50 1-butanol:propanoic acid solution is then added to the 500 ml flask up to the mark, and a stir bar is then added. The solution is stirred for an additional 12 hours.
