Kinetics and efficiency of solar energy storage in the photochemical isomerization of norbornadiene to quadricyclane

Kinetics and efficiency of solar energy storage in the photochemical isomerization of norbornadiene to quadricyclane. Philippopoulos, Constantine; Marangozis, John (Lab. Chem. Process Eng., Natl. Tech. Univ. Athens, Athens, Greece). Ind. Eng. Chem. Prod. Res. Dev., 23(3), 458-66 (English) 1984. CODEN: IEPRA6. ISSN: 0196-4321. DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 22, 74 The conversion of norbornadiene [121-46-0] to quadricyclane by polychromatic radiation in a solar simulator was investigated. Parameters examd. were photosensitizers, reactant and sensitizer concns., insolation power, and temp. The rate of conversion and the efficiency of solar energy storage were measured and quant. related. The most efficient sensitizers in the order of decreasing efficiency were Michler's ketone [90-94-8], acetophenone [98-86-2], and benzophenone [119-61-9]. A mixt. of the sensitizers performed worse than the less efficient sensitizer, perhaps due to a mechanism of inter-sensitizer energy transfer. Data were obtained by exposing the system to the actual sunlight, and repeated photochem. conversion-thermal reversion cycling was made. The kinetics of the thermal reverse reaction was investigated. This information is useful for the development of a photochem. solar energy storage system.
