摘要：

The carbon arc in liquid argon in presence of methane produces the complete series of polyynes from C4H2 to C12H2 which have been collected in a cold trap and analyzed by electronic absorption spectroscopy and by liquid chromatography ( HPLC-diode array). The relative abundance of the polyynes series has been determined. In addition to polyynes the decomposition of methane in the argon arc produces also vinylacetylene and naphthalene. Thermodynamic calculations explain why the polyynes are formed so easily in the carbon arc.
