science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: tetrafluorosuccinic anhydride Other Names: 3,3,4,4-tetrafluorodihydrofuran-2,5-dione Formula: C4F4O3 CAS-No.: 699-30-9 Study: photolysis, quantum yields Authors: P. E. Watkins, E. Whittle Title: Photochemistry of anhydrides. Part 5.-Photolysis of perfluorosuccinnic anhydride Journal/Source: J. Chem. Soc., Faraday Trans. I, 76, 503-511, (1980); DOI: 10.1039/F19807600503 Data: (diagram, table, disk): Energy/Wavelength range: Resolution: Temperature: 295 K; 472 K Temperature dependence: Pressure/Concentration: Phase (gas, liquid, solid): vapor pH: Comments: The photolysis of the vapour of perfluorosuccinnic anhydride was studied at 22 and 199°C. The quantum yields of products are little affected by change of pressure but they decrease on increasing the pressure of anhydride or of added perfluoromethylcyclohexane.
