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

open access: yesChemical 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

Vapor Pressure of Ionic Liquids [PDF]

open access: yes, 2009
We argue that the extremely low vapor pressures of room temperature ionic liquids near their triple points are due to the combination of strong ionic characters and of low melting temperatures.Comment: Initially submitted manuscript of article M.

Design of low-cost ionic liquids for lignocellulosic biomass pretreatment [PDF]

open access: yes, 1972
The cost of ionic liquids (ILs) is one of the main impediments to IL utilization in the cellulosic biorefinery, especially in the pretreatment step. In this study, a number of ionic liquids were synthesized with the goal of optimizing solvent cost and ...

Lattice model of ionic liquid confined by metal electrodes [PDF]

open access: yes, 2018
We study, using Monte Carlo simulations, the density profiles and differential capacitance of ionic liquids confined by metal electrodes. To compute the electrostatic energy, we use the recently developed approach based on periodic Green’s functions. The
