Rapid Carbonation for Calcite from a Solid-Liquid-Gas System with an Imidazolium-Based Ionic Liquid
Aqueous carbonation of Ca(OH)2 is a complex process that produces calcite with scalenohedral calcite phases and characterized by inadequate carbonate species for effective carbonation due to the poor dissolution of CO2 in water. Consequently, we report a solid-liquid-gas carbonation system with an ionic liquid (IL), 1-butyl-3-methylimidazolium bromide, in view of enhancing the reaction of CO2 w...
متن کاملCovalent Modification of Glassy Carbon Electrode with an Imidazolium based Methoxysilyl Ionic Liquid Nanoparticles: Application in Determination of Redox System
Glassy carbon (GC) is the most commonly used carbon-based electrode in the analytical laboratory. Because of the high background current and low electrode response, modification of this electrode can be done by various materials and techniques. An ionic liquid (IL), 1-methyl-3-(3-trimethoxysilyl propyl) imidazoliumbis (trifluoromethylsulfonyl) imide, was covalently cross linked onto the GC surf...
متن کاملThermodynamics of cellulose dissolution in an imidazolium acetate ionic liquid.
The heat of dissolution of cellulose in one imidazolium acetate ionic liquid was determined experimentally. The value of -132 ± 8 J g(-1) indicates that the dissolution is exothermal thus confirming energetically favourable cellulose-ionic liquid interactions but indicating that an increase in temperature does not thermodynamically favour the dissolution process.

متن کاملApplication of Imidazolium based ionic liquid Nano-emulsions for the removal of H2S from crude oil
Hydrogen sulfide is one of the most dangerous contaminants in crude oil and natural gas that have to be removed prior to the transfer and refining. In this study, hydrophobic ionic liquid, i.e. 1-ethyl-3-methylimidazolium methylflour, [EMIM] [NTf2], was used as scavenger for the reduction of the H2S. Due to its ionic nature, [EMIM] [NTf2] forms nanoemulsion in crude oil media and hence can diss...
