The kinetics for the dissolution of fullerene C60 in N-methyl-2-pyrrolidone (NMP) solvent are investigated through measurements of the stirring speed and temperature dependence of the UV-Vis absorption spectra. We develop a model for the kinetics of simultaneously occurring processes in the solution, employing a system of simple kinetic equations and obtain the corresponding parameters dependence on preparation conditions. The obtained results will allow one in the future to consider these effects when modeling the slow growth kinetics of large clusters in C60/NMP solutions.
Keywords: kinetics of dissolution, fullerene, N-methyl-2-pyrrolidone, UV-Vis.
