Abstract: A series of perhalogenated aromatic compounds were synthesized by arc-discharging of solid polytetrafluoroethylene and glow-discharge of chloroform vapor, respectively. Among the products, perchloropyrene(C₁₆Cl₁₀) and perfluoropyrene(C₁₆F₁₀) were separated and characCM) terized. The features of the plasma reaction and product formation mechanism have been discussed. The products of the plasma reaction are normally a series of compounds with similar structure. Their formation appeared not to be affected by the compositions or structures of the reagents, as well as the discharge conditions.

Key words: perchloropyrene, perfluoropyrene, plasma synthesis, arc-discharge, glow-discharge
