TLDR
In this article, a stoichiometric reaction of dichromate and oxalate in 1∶1 ratio to give the corresponding chromate as the sole product was shown.Abstract:
The thermal investigation of the reaction taking place between dichromates and oxalates in the solid state has been done taking two systems of potassium dichromate-potassium oxalate and sodium dichromate-sodium oxalate. The techniques employed include thermogravimetry, differential thermal analysis, infrared spectroscopy and X-ray diffraction studies. The results indicate a stoichiometric reaction of dichromate and oxalate in 1∶1 ratio to give the corresponding chromate as the sole product.read more

TL;DR: The validity of the modulated synthesis approach was confirmed for a diverse set of Al‐MOFs, namely X‐MIL‐53 (X=OH, CH3O, Br, NO2), CAU‐10, MIL‐69, and Al(OH)ndc (ndc=1,4‐naphtalenedicarboxylate), highlighting the potential benefits of extending the use of this modulator to other coordination materials.

Isothermal decomposition of K 2 C 2 O 4
TL;DR: In this article, the effect of semiconducting metal oxide (CuO and TiO2) additives on the kinetics of thermal decomposition of potassium oxalate (K2C2O4) to potassium carbonate has been studied at five different temperatures in the range 793-813 K under isothermal conditions by thermogravimetry.
Effect of metal oxide additives on the decomposition kinetic
TL;DR: In this article, the effect of semiconducting metal oxide (CuO and TiO2) additives on the kinetics of thermal decompo- sition of potassium oxalate (K2C2O4) to potassium car- bonate has been studied at five different temperatures in the range 793-813 K under isothermal conditions by thermo- gravimetry.
