SONOCHEMICAL DECOMPOSITION OF LIQUID BENZENE - FORMATION OF CARBON FINE PARTICLES BY ADDITION OF CCL4

Sonochemical graphitization of liquid benzene has been studied. Sonoch emical reaction proceeds through production and collapse of a bubble i nduced by ultrasonics. During the collapse, high temperature and high pressure conditions can be realized and the degradation of molecules o ccur, then, fine particles are formed. In order to produce carbon fine particles from liquid benzene, we attempted hydrogen abstraction by c hlorine atoms which are produced through degradation of carbon tetrach loride. The formation of graphitic carbon could be confirmed through R aman spectroscopy.
