    By coupling two CL reactions, i.e. H 2O 2-acetonitrile-tetracycline (working reaction) and H 2O 2-acetonitrile-melatonin (reference reaction), sodium azide could be clearly identified and quantitatively determined in the presence of other similar compounds.
    实验结果证明 :偶合下列两个反应 :H2 O2 CH3 CN 四环素 (工作反应 )和H2 O2 CH3 CN N 乙酰 5 甲氧基色胺 (参比反应 ) ,我们能够从多种相似的自由基淬灭剂中选择性地识别出叠氮化钠 .

The effect of the decrease in bremsstrahlung energy on the yields of these main products is examined. The yields of 22 nuclides and the upper limits of yields of 3 nuclides, both as impurity activities, are also measured or estimated. On the basis of these results, the potential of electron linear accelerator in producing these main products is evaluated, the nuclear purity that may be obtained for the main products and the requirement for decontamination of the impurity activities in chemical processing are estimated.

In this paper, we used the flowing-afterglow technique to study the energy transfer processes of metastable He with several methyl halides. Taking the reaction He(2~3s)+CO as a reference reaction, we measured the absolute rate constant for the formation of electronically excited products from the reaction of He(2~3s) with CHCl_3,CH_2Cl_2,CH_2Br_2 and CH_3I. Finally, we discussed the formation.mechanism of the excited fragments.

The radioactive countings in the sample of catalyst reaction system are two order of magnitude higher than that of reference reaction system. The measured results of liquid scintillation indicate the protons transfer to catalytic solution from acetylene at the same of formation media for Cu(I) with acetylene. This...

The dimerization of acetylene in Niculand catalytic system (CuCl-NH4Cl-H2O) has been studied for the first time by means of 3H labeled acetylene at 60± 0.1℃ . Some conclusion has been obtained. The radioactive countings in the sample of catalyst reaction system are two order of magnitude higher than that of reference reaction system. The measured results of liquid scintillation indicate the protons transfer to catalytic solution from acetylene at the same of formation media for Cu(I) with acetylene. This conclusion is also applicable to the general aqueous system of coordination reaction for acetylene with Cu(I).
