Green Polymerization of Vinyl Acetate Using Maghnite-Na+, an Exchanged Montmorillonite Clay, as an Ecologic Catalyst

In this work, the green polymerization of vinyl acetate is carried out by a new method which consists in the use of clay called Maghnite-Na+ as an ecological catalyst, non-toxic, inexpensive and recyclable by a simple filtration. X-ray diffraction and scanning electron microscopy showed that Maghnite-Na+ is successfully obtained after cationic treatment (sodium) on crude maghnite.

Ionic Liquid-Functionalized Titanomagnetite Nanoparticles as Efficient and Recyclable Catalyst for Green Synthesis of 2,3-Dihydroquinazolin-4(1H)-ones

In the present study, titanomagnetite nanoparticles (Fe3-xTixO4 NPs) were synthesized via coprecipitation approach and then functionalized using 3-trimethoxysilylpropyl chloride silan coupling agent followed by tetrabutylammonium asparaginate through a facial and newly one-pot procedure to afford an ionic liquid (IL)-modified Fe3-xTixO4 NPs.

Natural deep eutectic solvents in extraction process

Developing new, eco-friendly solvents which would meet technological and economic demands is perhaps the most popular aspects of Green Chemistry. Natural deep eutectic solvents (NADES) fully meet green chemistry principles. These solvents offer many advantages including biodegradability, low toxicity, sustainability, low costs and simple preparation. This paper provides an overview of knowledge regarding NADES with special emphasis on extraction applications and further perspectives as truly sustainable solvents.
