Abstract:
The action of ultrasonic and hydrodynamic cavitation on the cracking of organic compounds of various natures (linear alkanes (octane, undecane, and hexadecane), carboxylic acids (decanoic and oleic acids), alcohols (decanol), and esters (ethyl caprate)) and transesterification of rapeseed oil and methanol and ethanol was studied. An analysis of hydrocarbon transformation products by gas chromatography, high-performance liquid chromatography, NMR, and chromato-mass spectrometry showed that cavitation treatment of any class of organic compounds of those mentioned above resulted in transformations no more than 1.1% deep. In experiments with transesterification of rapeseed oil and methanol and ethanol without a catalyst under the action of cavitation, the yield of fatty acid esters did not exceed 2.1 mol %. The energy efficiency of the cavitation apparatus was estimated at 0.002% for endothermic cracking of alkanes. The data obtained led us to conclude that the use of cavitation directly for performing cracking of various organic compounds and noncatalytic transesterification of vegetable oils was ineffective.
