Determination of Assay for Tetrabutyl Ammonium Phosphate
Mar 23, 20221.Analysis Steps
Accurately weigh 0.8g sample into 250mL erlenmeyer flask (accurate to 0.0002g), add 150ml water to dissolve , and then add three drops of phenolphthalein indicator. Titrate with 0.1mol/l sodium hydroxide standard solution to pink as the end point.
2.Result Calculation
Assay of Tetrabutyl ammonium phosphate X (%), calculate as formula:
In formula:
V: Consumed volume of sodium hydroxide standard solution, mL;
N: Molar concentration of sodium hydroxide standard solution, mol/L;
W: Milligram molecular weight of the sample;
M: Mass of measured sample, g.
