Iron-Catalyzed Synthesis of 4-oxo-1,3-dioxolanes (DOXs) Using Lactic Acid: From Homogeneous to Heterogeneous Behaviors

Our commitment to proposing eco-friendly chemical compounds, alternatives to those currently, in use also translates into identifying new, more convenient and sustainable methods of preparation, such as the one described in this article for a class of innovative solvents.

Formulation and Recycling of a Novel Electrolyte Based on Bio-Derived γ-Valerolactone and Lithium Bis(trifluoromethanesulfonyl)imide for Lithium-Ion Batteries

Lithium batteries represent the main energy storage devices in use today. However, some of their components presented environmental issues; they are toxic and flammable. These articles demonstrate that their replacement is possible using renewable and low-impact compounds.

A lactic acid dioxolane as a bio-based solvent for lithium-ion batteries: physicochemical and electrochemical investigations of lithium imide-based electrolytes

In this study we report for the first time the application of an emerging bio-based solvent derived from lactic acid, namely 5-methyl-1,3-dioxolan-4-one (LA-H,H), as an electrolyte component for lithium-ion batteries (LIBs). Electrolyte formulations consisting of this new bio-solvent and immide-based conducting salts (i.e., lithium bis(trifluoromethanesulfonyl)immide, LiTFSI, and lithium bis(fluorosulfonyl)immide, LiFSI) together with the additive vinylene carbonate (VC) were prepared and thoroughly evaluated.

Heterogeneous Brønsted Catalysis in the Solvent-Free and Multigram-Scale Synthesis of Polyalcohol Acrylates: The Case Study of Trimethylolpropane Triacrylate

Acrylic acid esters resulting from its reaction with polyalcohols have great relevance in many application areas, such as in the formulation of plastics, adhesives and paints. Their preparation is laborious due to the chemical properties of acrylic acid, which tends to spontaneously polymerize resulting in undesirable products. This paper describes the preparation in high yields of an ester by a convenient catalytic procedure that allows solvent exclusion and catalyst recycling.

Glycerol: a green solvent for synthetic chemistry

Glycerol is a biodegradable, nontoxic, nonvolatile, and water-soluble liquid, qualities that make it valuable in various applications. It is currently obtained as a by-product of biodiesel production in quantities of millions of tons per year. Therefore, to make biodiesel production sustainable, its full potential must be exploited. This review describes its fruitful use as a solvent of relevant synthetic importance.
