High frequency glow discharge

Vapor phase pyrolysis of 2-aminobiphenyl in chloroform at 350°C produces carbazole,as does heating at 500-800°C in a high-frequency glow discharge at 25-34 A small amount (11%) of carbazole 280 was formed during the reaction of 281 with copper-potassium carbonate and 1-iodo-naphthalene in nitrobenzene. ... [Pg.175]

A glow-discharge (non-isothermal) plasma is generated in a gas by a high-frequency electric field, such as microwave (2.45 GHz), at relatively low pressure.P9] In such a plasma, the following events occur ... [Pg.136]

This obiously does not exclude the possibility of oscillation phenomena such as ionization waves, etc., which are among the most frequently observed instabilities in d.c. glow discharges49. Any allowance for these phenomena in the theoretical treatment of chemical processes would introduce major complications and, we shall therefore ignore them in the first approximation. Such a simplification is justified, because the relaxation processes related to the ionization waves are usually much faster than chemical processes. Therefore, the oscillations take place on a time scale which is different from that of the chemistry. Moreover, the waves arise in a d.c. discharge rather than in a high frequency discharge, which was used in most experiments on chemical transport. [Pg.146]
