|Section2= }} ε-Caprolactone or simply caprolactone is a cyclic ester, a member of the lactone family, with a seven-membered ring with the formula (CH2)5CO2. This colorless liquid is miscible with most organic solvents. It is produced on a very large scale as a precursor to caprolactam. ==Production and uses== The great majority of caprolactone is consumed, often in situ, as a precursor to caprolactam.〔Josef Ritz, Hugo Fuchs, Heinz Kieczka, William C. Moran "Caprolactam" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. 〕 It is also a monomer used in the manufacture of highly specialised polymers. Ring-opening polymerization, for example, gives polycaprolactone.〔Horst Köpnick, Manfred Schmidt, Wilhelm Brügging, Jörn Rüter, Walter Kaminsky "Polyesters" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH, Weinheim. 〕 Another polymer is polyglecaprone, used as suture material in surgery.〔http://www.curehunter.com/public/keywordSummaryC095495-glycolide-E-caprolactone-copolymer.do〕 Caprolactone is prepared industrially by Baeyer-Villiger oxidation of cyclohexanone with peracetic acid. The three main manufacturers are BASF in the USA, Daicel in Japan and the largest Perstorp in Sweden. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「caprolactone」の詳細全文を読む スポンサード リンク
