Problems solved by technology

[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

Embodiment 1

[0018] 1 kg of alkaline ionic liquid C 3 f 7 wxya 3 .[OH], 1 kilogram of concentration is that the aqueous hydrogen peroxide solution of 5mol / L is placed in the raw material storage tank and mixed and stirred, at this moment C 3 f 7 wxya 3 .[OH] absorbs hydrogen peroxide from aqueous hydrogen peroxide phase, C 3 f 7 wxya 3 .[OH] reacts with hydrogen peroxide to generate C 3 f 7 wxya 3 .[O 2 H], finally forming a C 3 f 7 wxya 3 .[O 2 A two-phase system in which the ionic liquid phase of H] and the hydrogen peroxide aqueous solution coexist; the ionic liquid phase is extracted into a small jet-type singlet oxygen generator to react with chlorine gas, and the singlet oxygen can be obtained at the outlet of the generator. The other two products obtained hydrogen peroxide, C 3 f 7 wxya 3 .[Cl] and unreacted C 3 f 7 wxya 3 .[O 2 H] return in the raw material storage tank, hydrogen peroxide will automatically enter the aqueous hydrogen peroxide phase, and C 3 f ...

Abstract

The invention relates to a method for generating singlet oxygen in the technical field of oxygen-iodine chemical lasers. In this method, a water-immiscible alkaline ionic liquid is mixed with an aqueous hydrogen peroxide solution to form a two-phase transfer system, and the transferred ionic liquid phase is reacted with chlorine gas to generate singlet oxygen, realizing the realization of water and singlet oxygen. Oxygen isolation. The method helps to reduce the quenching effect of water on singlet oxygen and reduces the water content in singlet oxygen. On the other hand, due to the enrichment effect of alkaline ionic liquids on hydrogen peroxide, it is expected to effectively solve the bottleneck problem of hydrogen peroxide concentration limitation faced by oxygen iodine chemical lasers in the regeneration of raw materials under traditional technical conditions. Therefore, the invention is of great significance for improving the singlet oxygen yield of the oxygen-iodine chemical laser, reducing the singlet oxygen water content and solving the problem of raw material regeneration.

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...
