摘要
采用 35 5nm紫外光照射HNO2 萘 H2 O体系 .研究表明 ,光照后体系中间产物和最终产物的光反应过程是通过HNO2 激光光解产生OH自由基 ,OH自由基再与萘反应生成 OH ,反应速率常数为 ( 1 1± 0 1 )× 1 0 1 0 M- 1 ·s- 1 .
We studied the microscopic reactions taking place in the mixed solution of nitrous acid and naphthalene after its exposure to the 355nm UV light irradiation.Experiment results suggested the main final products of this system to be naphthoquinone,naphthol and nitronaphthol.The OH radical generated through the photolysis of nitrous acid would from adduct with naphthalene quickly,while this adduct has been found to be the precursor of all of the final products identified.The rate constants of reaction OH+naphthalene was determined to be (1 1±0 1)×10 10 M -1 ·s -1 .
