Article Synopsis
- The study introduces an aminosilicone solvent mix specifically designed to capture CO(2), utilizing a hydroxyether co-solvent to keep it in a liquid state for better absorption.
- The solvent system was tested and successfully regenerated over 6 cycles, showing a 25-50% improvement in CO(2) capacity compared to 30% MEA.
- Additionally, the research validated continuous CO(2) absorption and found that predictions for reaction heats matched well with experimental data.
Germanium dioxide in the presence of 5% KOH reacted with dimethyl carbonate (DMC) at 250 degrees C to give (MeO)(4)Ge. The reaction of GeO(2) and DMC is similar to that reported for SiO(2); however, the rate of reaction for germanium is much higher than that of the corresponding silicon reaction. In a side-by-side experiment using SiO(2) and GeO(2) where the surface area of the silicon dioxide was 2 orders of magnitude higher than that of the GeO(2), the base-catalyzed reaction with DMC was about an order of magnitude higher for the germanium dioxide.

Several commercially available diatomaceous earth materials were investigated. High throughput screening was employed to explore over 200 silicate rocks and minerals as alternative silicon dioxide sources for formation of Q' from DMC and base.
