Optimization of Operating Parameters for SonoChemistry are dependent upon. "The magnitudes of collapse pressures and temperatures as well as the number of free radicals generated at the end of cavitation events and hence the intensification obtained due to the cavitation phenomena for any physical or chemical processing applications are strongly dependent on the operating parameters of the equipment namely, frequency and intensity of irradiation along with the geometrical arrangement of the transducers, geometry of the reactor, the liquid phase physicochemical properties, which affect the initial size of the nuclei and the nucleation process and the operating temperature." - Theoretical and Experimental Sonochemistry Involving Inorganic Systems, Page 50.

As a naturally occurring polymer, cellulose always contains small amounts of other constituents in addition to glucose (over 99%). Most of these changes result from secondary reactions, i.e. hydrolysis or oxidation, during isolation of cellulose from natural resources. However, they also may already be partially built into or onto the cellulose molecules during biosynthesis, such as lignin-cellulose complexes
