사이클로부타논 C화학적 특성, 용도, 생산
화학적 성질
Clear colourless to slightly yellow liquid용도
Cyclobutanone is used in preparation of cyclobutane derivatives. It is used as a starting material for aminocyclobutanecarboxylic acid through sulfonyloxiranes. It is also used to prepare dihydro-furan-2-one in presence of polystyrene-bound phenylselenic acid as catalyst. Further, it is involved in the photochemical synthesis of nucleoside analogues such as bicyclic nucleosides and isonucleosides.제조 방법
The Russian chemist Nikolai Kischner first prepared cyclobutanone in 1905. He synthesized cyclobutanone in a low yield from cyclobutanecarboxylic acid in several reaction steps.Another synthesis of cyclobutanone involves lithium-catalyzed rearrangement of oxaspiropentane, which is formed by epoxidation of the easily accessible methylenecyclopropane.
Purification Methods
Treat cyclobutanone with dilute aqueous KMnO4, dry it with molecular sieves and fractionally distil it. Purify it via the semicarbazone, then regenerate the ketone, dry it (CaSO4), and distil it in a stainless steel spinning-band (or Vigreux, p 11) column. Alternatively, purify it by preparative gas chromatography using a Carbowax 20-M column at 80o. (This treatment also removes acetone). The oxime has m 84-85o (from pet ether) and the semicarbazone has m 212-212-5o (220-221o from MeOH or H2O, Buchanan et al. J Am Chem Soc 64 2701 1942).
