摘要
FIELD: organic chemistry. SUBSTANCE: aromatic hydrocarbons are charged into electroconductive metal container which is placed into evacuated or argon-filled chamber. Alternating electric current having frequency 4-10 kHz is applied to collectors of chamber to heat it up to 500-2000 C. In addition, chamber is heated by applying to it ultrasonic of power 1.5±0.2 kW, and frequency 22±5 kHz and/or magnetic field generated by magnetron. By controlling alternating current frequency, it is possible to achieve predetermined ratio of fullerens fractions (C60,C70, etc.). EFFECT: higher output and reduced wastes. 10 cl
