Production of singlet oxygen by the reaction of non-basic hydrogen peroxide with chlorine gasElectronic supplementary information (ESI) available. See DOI: 10.1039/c2cp41690e
Non-basic hydrogen peroxide was found to be very easy to react with Cl 2 to produce singlet oxygen O 2 (a 1 Δ g ) ( i.e. the molecular oxygen in its first electronic excited state) when an H + absorbent such as C 5 H 5 N, CH 3 COONH 4 , HCOONH 4 or NH 4 F was added into H 2 O 2 aqueous solution, and...

can react with Cl

absorbent has provided a stronger base than H

O to absorb the H

produced during the reaction that O

(a

) can be produced.
