A new co-solvent method for the green production of biodiesel fuel – Optimization and practical application
Le Tu Thanh,Le Tu Thanh,Kenji Okitsu,Yasuhiro Sadanaga,Norimichi Takenaka,Yasuaki Maeda,Hiroshi Bandow +6 more
TL;DR: In this article, an homogeneous reaction process using acetone as a co-solvent for the transesterification of vegetable oils with methanol in the presence of potassium hydroxide catalyst has been developed.

Effect of reaction vessel diameter on sonochemical efficiency and cavitation dynamics.
TL;DR: The influence of reaction vessel diameter on the sonochemical yield was investigated by using reaction vessels with five different diameters and suggested that active cavitation bubbles were formed at certain zones and that bubble nuclei that have not grown up to the resonance size, escaped from the sonication zone to the non-sonication zone and dissolved away.

Sonochemical degradation of various monocyclic aromatic compounds : Relation between hydrophobicities of organic compounds and the decomposition rates
TL;DR: The hydrophobicity of the compounds significantly affected their accumulation at the gas-liquid interface of the bubbles and it was the most important factor for the sonochemical degradation of aromatic compounds and LogP was found to be the representative parameter for understanding the hydrophobic properties of water-insoluble compounds.
