Accelerated phase transition and synthesis of magnesite from hydromagnesite in aqueous mono-ethylene glycol solution

Mechanisms of Mg carbonates precipitation and implications for CO2 capture and utilization/storage

“…monoethylene glycol). 147 When high pressures (100-150 bar) and high temperatures (150-180 °C) are employed, the precipitation of magnesite is observed without any noticeable formation of intermediate precipitates. Montes-Hernandez et al (2012) have observed that in conditions of ambient temperature and moderate pressures (50 bar), the precipitation of magnesite is facilitated by the presence of NaOH, which is assumed to have a catalytic role in the reaction.…”
