The investigations on the photochemical reaction of chlorobenzene with nitrogen oxides in air were carried out using the reaction vessels made of Pyrex glass and quartz, respectively. The irradiation of chlorobenzene in the Pyrex glass vessel gave m-chloronitrobenzene, 2-chloro-6-nitrophenol, 2-chloro-4-nitrophenol and 4-chloro-2-nitrophenol, while the irradiation of chlorobenzene in the quartz vessel resulted in m-chloronitrobenzene, p-nitrophenol, 2-chloro-4-nitrophenol, 3-chloro-2-nitrophenol, 3-chloro-6-nitrophenol and 3-chloro-4-nitrophenol.The formation mechanism of these chloronitrophenols was considered using the theory of the nitro-nitrite rearrangement of chloronitrobenzenes. 相似文献

固定源氮氧化物排放及控制技术应用 总被引:2,自引:0,他引:2
固定源是氮氧化物排放的一个主要来源。通过对主要固定源氮氧化物生成机理及现有的排放控制技术进行论述,分析我国固定源氮氧化物排放的实际情况,提出我国固定源氮氧化物排放控制还处于起步阶段,氮氧化物排放标准相对宽松,氮氧化物排放控制技术有待进一步普及,并提出固定源氮氧化物排放治理的一些建议。 相似文献
