This product is calculated as anhydrous, containing (C4H10N2)3 • 2C6H807 not less than 98.5%.
take 0.50g of this product, Add 10ml of water and 10% ml of 1.0 sodium hydroxide solution, shake to dissolve, add 1.0ml of acetone and ml of sodium nitrosoferricyanide solution, mix well, and place it accurately for 10 minutes; the same amount of reagent was taken separately, but water was used instead of the 10% sodium hydroxide solution as a blank. The absorbance was measured at wavelengths of 0401 nm and Nm respectively according to UV-visible spectrophotometry (general rule). The ratio of the absorbance at a wavelength of 600nm to the absorbance at a wavelength of 520nm should not be more than 0.50 (equivalent to about 0.1% of the first amine and ammonia).
take this product, according to the moisture determination method (General 0832 first method 1), the moisture content should be 10.0% ~ 14.0%.
not more than 0.1% (General rule 0841).
take 2.og of this product, add water 35ml and hydrochloric acid 3ml to dissolve, add ammonium persulfate 50mg and ammonium thiocyanate solution (30-100)3ml, then add appropriate amount of water to make 50ml, shake well, add butanol 20ml, after extraction by shaking, after placing them into layers, the butanol layer shall be separated and taken out. In case of color development, the butanol layer shall not be deeper (0.0005%) compared with of standard iron solution prepared by the same method.
take this product 2. G, add water dissolved in 0821, add dilute hydrochloric acid 4. OML, inspection according to law (general principles the first law), containing heavy metals shall not exceed 10 parts per million.
take this product about 0.lg, precision weighing, add glacial acetic acid 30ml, shake to dissolve, add crystal violet indicator solution 1 drop, with perchloric acid titration solution (0.1 mol/L) titration to the solution is blue-green, and the result of the titration is corrected with a blank test. Each 1 ml of perchloric acid titration solution (0.1 mol/L) corresponds to 10.71mg(C4H10N2)3.2C6H80.
