Abstract：In order to prepare the high-purity carbon chain samples at large scale and study the preparation mechanism of carbon chains with liquid arc discharge method, a new collection method for carbon chains was proposed.The overflowed gas generated in the arc discharge process was collected with ethanol solution, and the consitituent of overflowed gas was analyzed.In addition, the overflowed gas was seperated from the ethanol solution with the high performance liqiud chromatograph, and the absorption spectra of the overflowed gas were analyzed.The results show that the overflowed gas contains a large quantity of short carbon chains maily composed of C8H2, and the component of overflowed gas is consistent with that of azeotrope obtained during the distillation of carbon chains in methanol solution.It indicates that the overflowed gas generated in the arc discharge process is an azeotrope with carbon chains.Furthermore, the short carbon chains C8H2 at a large scale can be produced through collecting the overflowed gas generated in the arc discharge process.
