2019, Applied Thermal EngineeringCitation Excerpt :It has been widely reported that the combination of microwave and ultrasound irradiation is capable of improving the performance of various processes drastically when compared to individual irradiation. For instance, Cravotto et al. [1] reported that MW-US irradiation significantly improves the reaction time and yield of cross- and homo-coupling process when compared to individual irradiation. Cravotto et al. [2] showed that MW-US greatly enhances the yield of vegetable oil extraction.
Pd(0) nanocatalyst stabilized on a novel agar/pectin composite and its catalytic activity in the synthesis of biphenyl compounds by Suzuki-Miyaura cross coupling reaction and reduction of o-nitroaniline
2018, Carbohydrate PolymersCitation Excerpt :From the standpoint of green chemistry, (i) researchers have tried to reduce excess use of energy, solvent, and time, and (ii) they have worked to prevent waste which forms after the reaction. In order to eliminate these drawbacks, unconventional synthesis methodologies such as microwave irradiation (MW), ultrasound, grinding, sunlight, and photo-activation methods have gained more attention than the conventional heating technique in organic reactions (Cravotto et al., 2005; Martina, Manzoli, Gaudino & Cravotto, 2017). Among these unconventional techniques, MW has been widely used in organic reactions due to its advantages such as completion of reactions in short time like a few minutes, acquisition of high reaction yields, and ability to work in solvent-free media (Priya, Selvakannan, Chary, Kantam & Bhargava, 2017; Sabbatini et al., 2014).
