Ultrasound treatment of coal tar increases the yield of pitch by a factor of 1.5 in subsequent oxidation by atmospheric oxygen. The yield of pitch may be regulated in terms of its softening temperature by changing the oxidation time. To obtain standa

Radical cations derived from saturated hydrocarbons are highly reactive oxidizing species, and the rates of their bimolecular reactions are often determined by the frequency of diffusion collisions in solution. It is known that reactions of primary r
