In-depth process parameter investigation into a protic ionic liquid pretreatment for 2G ethanol production
(2021-07-01)
Protic ionic liquids (PILs) are promising pretreatment agents that can efficiently deconstruct lignocellulosic biomass for 2G ethanol production. PIL synthesis is less costly than that of aprotic imidazolium-based ILs ...
The Effect of the Ionic Strength of Nutrient Solution on Gas Exchange, Ionic Concentration and Leaf Biomass of Annona emarginata (Schltdl.) H. Rainer Variety ‘Terra-Fria’ Seedlings
(2015-01-01)
The present study aimed to test the hypothesis that different levels of the availability of mineral nutrients from Hoagland and Arnon's nutrient solution no. 2 affect the photosynthesis, ionic concentration and biomass ...
Influence of the anion nature and alkyl substituents in the behavior of ionic liquids derived from phenylpyridines
(Elsevier B.V., 2018)
© 2017 Quaternary alkyl 2-phenylpyridinium and 2-(2,4-difluorophenyl)pyridinium amines with iodide, hexafluorophosphate and bis(trifluoromethylsulfonyl)imide anions have been fully characterized by 1H NMR, FT-IR and MALDI ...
Removal of Cu2+ and Zn2+ from aqueous medium using ionic polyacrylamides
(Global NEST, 2017-03-28)
SPEEK-based proton exchange membranes modified with MOF-encapsulated ionic liquid
(2019-10-01)
Ionic liquids (ILs) 1-butyl-3-methylimidazolium hydrogensulfate (BMI.HSO4), 1-butylimidazole hydrogensulfate (BImH.HSO4) and 3-triethylammonium propane sulfonic hydrogensulfate (TEA-PS.HSO4) were encapsulated in UiO-66 ...
Improving the performance of a glucose biosensor using an ionic liquid for enzyme immobilization. On the chemical interaction between the biomolecule, the ionic liquid and the cross-linking agent
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The effect of the room temperature ionic liquid (1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([BMMI][BF4])) on the immobilization of glucose oxidase (GOx) was studied. The electrochemical performance of biosensors ...
Lewis Acidity/Basicity Changes in Imidazolium Based Ionic Liquids Brought About by Impurities
(American Chemical Society, 2015)
We herein report on the effect that water molecules, present as impurities, in the vicinity of an ionic liquid model structure, may induce on the Lewis acidity/basicity patterns normally observed in these materials. Depending ...
Mechanistic pathways of aromatic nucleophilic substitution in conventional solvents and ionic liquids
(Royal Society of Chemistry, 2014)
Solvation effects on the reaction mechanism of the title reactions have been kinetically evaluated in 21 conventional solvents and 17 ionic liquids. Solvent polarity affects the catalyzed and non-catalyzed SNAr pathways ...
