Kinetics of precipitation of calcium carbonate in alkaline pH at constant supersaturation. Spontaneous and seeded growth

Article Abstract:

A study was conducted to analyze the seeded and unseeded precipitation of calcium carbonate from supersaturated aqueous solutions in a closed system. The study was carried out using double-walled, water-jacketed, thermostated Pyrex vessels under constant supersaturation conditions at 25 degrees C and at a pH of 9.0 and 10.0. Experimental results indicated that CaCO3 precipitated as vaterite under conditions of sustained supersaturation.

Characterization of the ability of C[O.sub.2] to act as an antisolvent for ionic liquid/organic mixtures

Article Abstract:

The ability of C[O.sub.2] to induce liquid/liquid-phase separation in mixtures of ionic liquids and organics is examined. The ability of C[O.sub.2] to act as an antisolvent has depended on the solubility of the C[O.sub.2] in the ionic liquid/organic mixture and strong hydrogen bonding between the ionic liquid and the organic has made it difficult for C[O.sub.2] to induce a liquid/liquid-phase secarbon compoundsparation.
