Preparation of 5-hydroymethylfurfural by dehydration of fructose in the presence of acidic ionic liquid
TL;DR: In this paper, the preparation of 5-hydroymethylfurfural (HMF) by the dehydration of fructose in the presence of the Bronsted acidic ionic liquid, 3-allyl-1-(4-sulfobutyl)imidazolium trifluoromethanesulfonate, as well as its Lewis acid derivative, 3]-al.
Journal ArticleDOI
Acidic ionic liquid modified silica gel as novel solid catalysts for esterification and nitration reactions
TL;DR: In this article, Covalent bond immobilized ionic liquids are prepared via radical chain transfer reaction of 1-allylimidazolium based ionic liquid on modified silica gel and proved to be recyclable heterogeneous acidic catalysts for esterification and nitration reactions.
Journal ArticleDOI
Viscosity of [bmim][PF6] and [bmim][BF4] at high pressure
TL;DR: The viscosities of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim] [PF6]) and 1-methyl-3methylamine tetrafluoroborate ([BF4]) were measured by using a rolling-ball viscometer.
Journal ArticleDOI
