purification of tellurium through thermal decomposition of plasma prepared tellurium hydride
Separation and Purification Technology, 2018Co-Authors: Leonid Mochalov, Alexander Logunov, A V Vorotyntsev, V M Vorotyntsev, Aleksandr MashinAbstract:Abstract For the first time tellurium has been purified by means of plasma-enhanced chemical transport Reaction With Intermediate formation of tellurium hydride (H2Te) and the following its thermal decomposition With formation of high-purity tellurium and hydrogen. Recently developed direct interaction of hydrogen With tellurium vapors at low pressure in inductively coupled non-equilibrium plasma discharge underlain the novel approach of purification. The metal and carbon-containing impurities behavior was also studied. The possible mechanism of their conversion during the process has been discussed. In order to demonstrate effectiveness of the suggested method, As2Te3 films have been prepared from the initial tellurium and tellurium after purification. They were studied by mass-spectrometry technique for comparison.

the Reaction of fullerene c 60 With 4 6 dimethyl 1 2 3 triazine formation of an open cage fullerene derivative
Journal of Organic Chemistry, 2001Co-Authors: Yasujiro Murata, Michihisa Murata, Koichi KomatsuAbstract:A thermal Reaction of fullerene C60 With 4,6-dimethyl-1,2,3-triazine (4) in o-dichlorobenzene gave azacyclohexadiene-fused fullerene derivative 5, by the Reaction With Intermediate azete 11, and then, after flash chromatography over SiO2, open-cage fullerene derivative 6 having an eight-membered ring orifice on the C60 cage. Compound 6 is assumed to be formed via addition of diradical Intermediate 13 to C60. Compound 6 underwent a further photochemical Reaction With singlet oxygen With the cleavage of one of the double bonds at the rim of the orifice to afford triketone derivative 8 having a 12-membered ring orifice.
