Hydrogen Storage and Release via Carbon Dioxide Hydrogenation to Formate Salts under High‐Pressure Conditions with Ir Complex and Subsequent Formic Acid Dehydrogenation

ChemistryOpen, Volume 14, Issue 4, April 2025.
We demonstrated the potential of formic acid for efficient hydrogen storage and regeneration through CO₂ reduction followed by dehydrogenation. Using Cp*Ir catalysts with an amino‐substituted bipyridine ligand, we achieved a 96 % yield of formic acid with a formate concentration of 0.81 mol/L under supercritical conditions, followed by dehydrogenation ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Effect of mobile phase composition on retention factor in supercritical fluid chromatography [PDF]

, 2019
　In supercritical fluid chromatography with a mixture of carbon dioxide and a modifier as the mobile phase, the relationship between retention factor k and modifier mole fraction x was derived as 1/kmix=xCO2/k0CO2 + xmod/k0mod, where kmix, k0CO2, and ...

Supercritical fluid extraction and chromatographic analysis (HRGC-FID and HRGC-MS) of Lupinus spp. alkaloids

Journal of the Brazilian Chemical Society, 2000
The alkaloid extracts from Lupinus spp., obtained by conventional methods (maceration/sonication - solid phase extraction; maceration/sonication - liquid-liquid extraction) and SFE (supercritical fluid extraction) using CO2 and modified CO2 (CO2/MeOH ...
