The use of acidic task-specific ionic liquids in the formation of high surface area mesoporous silica

The acidic ionic liquids 1-alkyl-3-methylimidazolium hydrogen sulfate [CnMIM]HSO4 (n = 8, 10, 12, 16) were synthesised using a one-pot method and then used as new acidic templates to generate high surface area ordered mesoporous sili

Dual functionality of amphiphilic 1-alkyl-3-methylimidazolium hydrogen sulfate ionic liquids: Surfactants with catalytic function

A series of amphiphilic 1-alkyl-3-methylimidazolium hydrogen sulfate ionic liquids were synthesized. Acidic hydrogen sulfate ionic liquids with the alkyl chains C6-C14 are characterized by good surface properties. Their surface properties (adsorption and micellization parameters, degree of ionization of micelles, Krafft temperatures and thermodynamic parameters) were determined. Synthesized ionic liquids were applied as a co-catalyst in an oxirane ring opening reaction in epoxidized fatty acid methyl esters (FAME). Their co-catalytic activities were determined and discussed as a function of their structure and surface properties. It was found that the co-catalytic properties, both conversion and selectivity, of alkylimidazolium hydrogen sulfate ionic liquids noticeably depended on the alkyl chain lengths, and in consequence their properties.

The efficient hydroxyalkylation of phenol with formaldehyde to bisphenol F over a thermoregulated phase-separable reaction system containing a water-soluble Bronsted acidic ionic liquid

The efficient hydroxyalkylation of phenol with formaldehyde to bisphenol F over a thermoregulated phase-separable reaction system containing a water-soluble Bronsted acidic ionic liquid was studied. The reaction system containing the water-soluble IL showed thermoregulated biphasic behavior with change of the alkyl chain length of IL, temperature and water amount. Four types of imidazolium-, ammonium-, phosphonium- and pyridinium-based water-soluble ionic liquids with different anions of dihydrogen phosphate [H2PO4]-, acetate [CH3COO] - and hydrogen sulfate [HSO4]- were used as both Bronsted acidic catalysts and thermoregulated solvents. Among them, [C6MIM][HSO4] gave a high yield of 80.5% and a selectivity of 96.9% for bisphenol F, and the optimal reaction conditions were stirring speed 450 rpm, phenol-formaldehyde ratio 6:1, IL catalyst molar concentration 12.5%, reaction temperature 90 °C and reaction time 1 h. [C 6MIM][HSO4] could be recovered by simple decantation and could retain its original activity even after six recycling-uses [C nMIM][HSO4] with the alkyl chain length n = 6 found to be the most suitable for the synthesis of bisphenol F because of both the formation of a thermoregulated monophasic reaction system at 90 °C to enhance the reaction efficiency and as a thermoregulated phase-transition solvent to facilitate its recovery from the reaction system. the Partner Organisations 2014.
