C-60 DETECTION IN SOOT FORMED IN BENZENE LIQUID SPRAY COMBUSTION IN ASHOCK-TUBE

This brief communication describes the observation of small amounts of C-60 in soot formed in the liquid spray combustion of benzene behind reflected shock waves. As far as we are aware this is the first report ed detection of C-60 in Shock waves at such high pressures and tempera tures. The soot containing C-60 was produced from combustion in argon containing 1% O-2 at temperatures of about 2400K and pressures about 2 .0 bar. Identification and separation of C-60 from co-produced polycyc lic aromatic hydrocarbons (PAHs) in the soot samples were made by H.P. L.C. and mass spectrometry.
