Two phase transfer system-based singlet state oxygen generation method

Abstract

The invention relates to a singlet state oxygen generation method, and belongs to the technical field of chemical oxygen-iodine lasers. The method comprises the following steps: mixing an alkaline ionic liquid insoluble in water with an aqueous hydrogen peroxide solution to form a two phase transfer system, and reacting the transferred ionic liquid phase with chlorine to generate singlet state oxygen in order to realize water and singlet state oxygen isolation. The method is helpful for reducing the quenching effect of water on singlet state oxygen, and reduces the content of water in the singlet state oxygen, and the alkaline ionic liquid has an enrichment effect on hydrogen peroxide to make effective solving of the bottleneck problem of hydrogen peroxide concentration restriction in the raw material regeneration process of chemical oxygen-iodine lasers under traditional technological conditions be possible, so the method is of great significance to improve the singlet state oxygen yield of the chemical oxygen-iodine lasers, reduce the water content of the singlet state oxygen and solve the raw material regeneration problem.

Description

technical field [0001] The invention relates to a method for generating singlet oxygen in an oxygen-iodine chemical laser, in particular to a method for generating singlet oxygen based on an alkaline ionic liquid-hydrogen peroxide aqueous two-phase transfer system. Background technique [0002] Oxygen-iodine chemical laser is currently the only chemical laser that successfully operates in electronic state transition, with a wavelength of 1.315 μm, just located in the atmospheric window, and has good application prospects in many aspects, so it has received extensive attention. [0003] singlet oxygen (O 2 ( 1 Δ)) As the energy source of the oxygen-iodine chemical laser, it has a direct impact on processes such as iodine dissociation and pump energy transfer. Whether the laser can operate normally and stably. Therefore, the acquisition of singlet oxygen is one of the most important problems in the research and design of oxygen iodine chemical lasers. [0004] Although the...

[0007] However, the above solutions significantly increase the operating cost of the oxygen iodine chemical laser

The abundance of heavy water in nature is low, and its extraction cost is extremely high. According to conventional supply channels, the price of 99.9D.% of heavy water reaches about 10,000 yuan per kilogram, which makes the operating cost of oxygen iodine chemical laser unacceptable

[0008] Therefore, if a new reaction system can be found, it can not only maintain the high-efficiency characteristics of the gas-liquid reaction system, but also avoid the H 2 The adverse effect of O on the active species in the oxygen iodine chemical laser is an ideal singlet oxygen generation system
