- 敏感性KETENE is extremely flammable. Mixtures with air are explosive. Reacts violently with water; reacts vigorously with alcohols, ammonia. Readily polymerizes and cannot be shipped or stored. Is obtained instead as needed from diketene. | DIKETENE is extremely flammable. Forms explosive vapor/air mixtures above 33 °C. Undergoes a further exothermic polymerization that is retarded by storage in the solid state (below -6.5 °C) or by the use of stabilizing additives. This polymerization becomes violent (with risk of fire or explosion) with warming or on contact with acids or bases. Reacts violently with water.

标题:Determination Of The Structural Arrangements Of Ketene Oligomers Using NMR,Ft-Ir And Esi-Ms
摘要:Oligomer Of Ketene Was Synthesized Using Glycine As The Source Material In Presence Of Free Electron Rich Carbon Through Free Radical Mechanism. The Structure And The Compositions Were Determined By Using C-13{h-1} NMR And Dept-135 Spectroscopy Measurements. Two-Dimensional Heteronuclear (Hetcor) NMR Spectroscopy Was Used To Resolve The H-1 NMR Spectrum Of The Polymer. The NMR Spectra Reveal That The Oligomers Were Generated As Oligoester (Oe),Oligoketene (Ok) And Oligoacetal (Oa) Structural Units. Esi-Ms And Atr-Ftir Also Support These Types Of Structural Units In The Crude Polymer. (C) 2006 Elsevier B.V. All Rights Reserved.
