Abstract: 
The isothermal kinetics of fullerol formation under different heating modes: conventional (CH), ultrasonic (USH) and microwave (MWH) was investigated. The isothermal kinetic curves of fullerol formation at different temperatures (293, 298, 303, 308 and 313 K) were measured. The kinetic model of the reaction was determined on the basis of the shape of the dependencies of reaction rate on fullerene concentration and on method of initial rates. The values of isothermal rate constants under different heating conditions and temperatures and their kinetic parameters were calculated. The effect of heating mode on the values of the kinetic parameters was established. The possibility of an existence of overheating and hot spots on the rate of fullerol formation was evaluated and discussed. The model of impact of USH and MWH on the reaction kinetics that is based on the model of selective energy transfer is suggested. The established effects of USH and MWH on the reaction of fullerol formation are successfully explained by that model.
