Special Issue Information

Dear Colleagues,

Sonochemistry (i.e., the use of power ultrasound in chemistry) has huge potential for innovation in eco-friendly and eco-efficient chemistry. After a first Special Issue published in 2016 (https://www.mdpi.com/journal/molecules/special_issues/sonochemistry_green), I have the pleasure to announce a second edition of the Special Issue in Molecules called “Sonochemistry and Green Chemistry Applications II” in order to highlight the significant progresses in this field. All areas of chemistry can contribute, such as organic chemistry and catalysis, preparation of materials, polymer chemistry, biomass valorisation, extraction, etc. Green chemistry is mainly based on basic concepts such as: (i) prevention, (ii) better use of the raw material, (iii) better waste management, (iv) energy savings, and (v) use of solvent compatible with the environment. When the experimental conditions are optimized, the use of power ultrasound is, in many cases, in favour of the twelve principles of green chemistry.

This Special Issue welcomes the submission of papers based on original research that describes sonochemical applications with a green chemistry approach. Particular attention to demonstrating this aspect in the submitted manuscript is requested, related to specific points or to the overall process. Submissions considering the 12 principles of green engineering, with notions of scale-up, energy consumption, and equipment design will also be appreciated. New combinations of power ultrasound with ionic liquids, microwave irradiation, enzymes, electrochemistry, or other technologies will be also considered.

As a conclusion, this Special Issue aims at showing that ultrasound is not just a simple mixing tool, but has a real role to play in the development of sustainable, green, and eco-efficient processes, to progress in innovations and the most exciting results.

The substitution of toxic precursors such as bisphenol A by renewable and safer molecules has become a major challenge. To overcome this challenge, the 12 principles of green chemistry should be taken into account in the development of future sustainable chemicals and processes. In this context, this paper reports the highly efficient synthesis of oligo-isosorbide glycidyl ethers from bio-based starting materials by a rapid one-pot heterogeneous ultrasound-assisted synthesis. It was demonstrated that the use of high-power ultrasound in solvent-free conditions with sodium hydroxide microbeads led for the first time to a fully epoxidated prepolymer with excellent epoxy equivalent weight (EEW). The structure of the epoxy precursor was characterized by FT-IR, NMR spectroscopy and high-resolution mass spectrometry (HRMS). The efficiency of the ultrasound-assisted synthesis was attributed to the physical effects caused by micro-jets on the surface of the solid sodium hydroxide microspheres following the asymmetrical collapse of cavitation bubbles.

This paper deals with the sonochemical water treatment of polycyclic aromatic sulfur hydrocarbons (PASHs), one of the most common impurities found in waste water coming from petroleum industry. The best fit of the experimental data appears to be the kinetic parameters determined using the Michaelis-Mentonmodel in the concentrations range of the study. For the initial increase in the degradation rates, it is simply considered that the more the bulk concentration increases, the more the concentration in the interfacial region increases. This will be explained by Michaelis-Menton kinetics. The influence of organic compounds in the water matrix as a mixture with Benzothiophene (BT) was also evaluated. The results indicated that BT degradation is unaffected by the presence of bisphenol A (BPA). Finally, the results indicated that ultrasonic action is involved in oxidation rather than pyrolitic processing in the BT sonochemical degradation. Full article
