Sodium carbonate revisited.
We present the structure of anhydrous sodium carbonate at room temperature (phase gamma) and 110 K (phase delta) based on single-crystal X-ray diffraction data. The incommensurate phase gamma was determined almost 30 years ago in the harmonic approximation using one modulation wave and first-order satellites. In our work we use satellites up to fifth order and additional harmonic waves to model...
متن کاملAn Evaluation of Sodium Carbonate as a Replacement for Sodium Hydroxide in Hydrogen Peroxide Bleaching of CTMP
A series of experiments was performed to evaluate the effect of substituting sodium carbonate for the sodium hydroxide used in peroxide bleaching of spruce CTMP. Three peroxide levels were tested: I , 2, and 4% HzOz, and two levels of causticsubstitution; SO% and 80%. At both the 2% and 4% peroxide levels, substituting 50% of the caustic charge with sodium carbonate decreased the initial bright...
متن کاملStability of hydrogen peroxide in sodium carbonate solutions
The rate of decomposition of hydrogen peroxide has been measured in aqueous, concentrated (0.1–1M) reagent-grade sodium carbonate liquors and compared with that in sodium hydroxide liquors at the same pH, temperature, and ionic strength. Over the ranges of temperature (303–323 K), pH (10.0–10.6), and ionic strength (1.5–3.0M), and without peroxide-stabilizing additives, hydrogen peroxide decomp...
متن کاملHydrothermal reactions from sodium hydrogen carbonate to phenol.
We report here experimental evidence for the hydrothermal formation of a pure organic molecule, phenol, from the reaction of carbonate with water in the presence of iron powders.
متن کاملGermicidal Efficiency of Sodium Hydroxide, Sodium Carbonate, and Trisodium Phosphate ^
In this paper the writers present results which they obtained, for the most part, in making a comparative study of disinfectants that, might be used by poultrymen, a fact which accounts for the choice of test organisms and various other details of the technic. Although, as the title implies, this work was done chiefly with the hydroxide, carbonate, and phosphate of sodium, the paper also report...
