New water-based nanocapsules of poly(diallyldimethylammonium tetrafluoroborate)/ionic liquid for CO capture.

Encapsulated ionic liquids as green solvents for CO capture are reported in this work. We present a novel combination of water-based poly(ionic liquid) and imidazolium-based ionic liquids (Emim[X]). Poly(diallyldimethylammonium tetrafluoroborate)/Emim[X] capsules were developed for the first time using Nano Spray Dryer B-90.

Dehydrating agent effect on the synthesis of dimethyl carbonate (DMC) directly from methanol and carbon dioxide.

CO emissions and global warming have increased with the growth of the world economy and industrialization. Direct synthesis of dimethyl carbonate (DMC) from CO and methanol (CHOH) has been considered a promising route from a green chemistry point of view due to global warming mitigation by CO emission reduction. However, DMC yield, when obtained by direct synthesis, is limited due to unfavorable thermodynamics and catalyst deactivation by water formation in the reaction process.
