✦ Synopsis

This phenomenon may be explained as follows: The ultrasonic energy is utilized initially to break up the petroleum molecules and the resultant free radicals' do not recombine easily when the sample weight in the flask is large. However, when the sample weight is small, the concentration of free radicals produced becomes relatively higher and the coupling of the radicals is easier. Accordingly, the polymerization of petroleum molecules may apparently take place. This explanation does not exclude the possibility that such reactive petroleum molecules as olefins should react with the free radicals produced.

These results with fuel oils appear to agree with those reported by Alexander and Fox' and Henglein" who found that ultrasonic irradiation caused degradation and/or polymerization of synthetic polymers.
