Immobilized tetrabutylammonium amino acid ionic liquids as heterogeneous catalyst in biodiesel production from Chlorella vulgaris

Chemical Engineering Journal Advances
Ionic liquids (ILs) are molten salts below 100 °C with the ability to be used as a catalyst for biodiesel production. However, to this date, the implementation of ILs as catalysts remains an enigma due to their practicability. Immobilizing ILs onto waste

Mixtures of ionic liquids

Chemical Society Reviews, 2012
Simple ionic liquids have long been held to be designer solvents, based upon the ability to independently vary their cations and anions. The formation of mixtures of ionic liquids increases this synthetic flexibility. We review the available literature of these ionic liquid mixtures to identify how their properties change and the possibility for their ...

Evaluating acute toxicity of amino acid ionic liquids towards Poecilia reticulata fish for designing sustainable chemical processes

Toxicology Reports
An acute toxicity study assessed the LC50 values for eight different amino acid ionic liquids (AAILs), featuring two cations, tetrabutylphosphonium [P4444] and tetrabutylammonium [N4444], coupled with four anions [PHE], [ASP], [SER], and [GLY]. According
