Abstract

Publisher Summary This chapter discusses the photo-induced oxidation reactions of ternary mixtures of hydrocarbon/O 2 /CO 2 . Partially oxidized products have been found to be produced in the case of ethane (C 2 H 6 ), ethylene (C 2 H 4 ), and cyclohexane (C 6 H 12 ). The chapter illustrates the case of C 2 H 4 to understand the behavior of typical olefinic hydrocarbons that are expected to trap some active species during the reaction. The main products from the mixture of C 2 H 4 /O 2 /CO 2 irradiated by a KrF excimer laser are C 2 H 4 O and CH 3 CHO under pressurized conditions. In the ethylene mixtures, the main products are ethylene oxide and acetaldehyde. The total quantum yield decreased with the increase of mixture density, but the branching ratio between the two products is almost independent on the density. The reaction for other hydrocarbons including ethane and cyclohexane is also discussed in the chapter.
