Product Description

Sodium Phosphotungstate with Cas 51312-42-6

Sodium phosphotungstate is a kind of chemical substance produced by the concentration and crystallization of sodium tungstate and hydrogen disodium phosphate in water after adding concentrated hydrochloric acid. Sodium phosphotungstate is mainly used for making pigments, but also as analytical reagents.

Mainly used for making pigments, but also as analytical reagents.

It is made from sodium tungstate and disodium hydrogen phosphate, which are soluble in water and condensed and crystallized after adding concentrated hydrochloric acid.

Dawson's heteropoly sodium tungstate was synthesized from tungstic acid and sodium dihydrogen phosphate by hydrothermal method. With P_2W_ (18) as catalyst and anhydrous ethanol as cocatalyst, mass fraction 30% aqueous solution of hydrogen peroxide as oxidant, under mild conditions to simulate the thiophene oxidation of fuel into sulfones: sulfoxide polarity, such as strong material, and with N, N - dimethyl formamide as extraction agent to extracted, it examines the reaction temperature, reaction time, dosage of hydrogen peroxide solution, dosage of extraction solvent and extraction series's influence on the desulfurization efficiency.
In a simulated fuel sulfur content (500 mg/L) 20 mL, P_2W_ (18) 0.030 g, 1.2 mL of anhydrous ethanol, hydrogen peroxide solution 0.12 mL, reaction time, reaction temperature 310 K 60 min, the volume of extraction agent and the oil phase is 1.0 3 times and extraction of optimized conditions, the desulfurization rate was 96.7%. After the end of the reaction, the simulated fuel oil can be separated from the catalyst by simple dumping. The catalyst can be reused for 5 times with good stability.
