Concomitant Carboxylate and Oxalate Formation From the Activation of CO2 by a Thorium(III) Complex

Improving our comprehension of diverse CO2 activation pathways is of vital importance for the widespread future utilization of this abundant greenhouse gas. CO2 activation by uranium(III) complexes is now relatively well understood, with oxo/carbonate formation predominating as CO2 is readily reduced to CO, but isolated thorium(III) CO2 activation is unprecedented. We show that the thorium(III)...

Comparison of the ammonium oxalate extraction of fertilizer for K2O, method 983.02, with the ammonium citrate/EDTA extraction, method 993.31.

The direct available method for phosphorus in fertilizers, Method 960.03, is an Official Method for extraction of both P2O5 and K2O. Because K2O is much more soluble and easier to extract than P2O5, the conditions of the extraction procedure are set for efficient extraction of P2O5, and the extraction of K2O is, in effect, a bonus. In 1993, a modified extraction procedure, using an extractant o...

X-ray evidence for a new phase in ammonium hydrogen oxalate hemihydrate under pressure

2014 Using an X-ray diamond anvil cell, we have found superlattice reflections, characteristic of the high pressure-low temperature phase III of NH4HC2O4, 1/2 H2O. At 77 K and 0.75 GPa, these peaks are located around each Bragg peaks of phase I at position (h, k, 1 ± 03B4) with 03B4 ~ 0.25. Revue Phys.
