Reagent Standard solution, impurity determination standard solution, preparation and products used in the absence of other requirements are marked by GB/T 601, GB/T 602, GB/T 603. The solution used in the test refers to the aqueous solution when it is not specified in the formulation of the solvent. A.2 Identification test Take a small amount of sample placed in water, easy to disperse in water, the formation of emulsion. A.3 Determination of acetone insoluble matter A.3.1 Methodological Summary With acetone dissolved in cold acetone and other acetone soluble matter, and then deducted n-hexane insoluble, the residue is acetone insoluble. A.3.2 Reagents and materials A.3.2.1 Acetone. A.3.2.2 petroleum ether. A.3.2.3 Modified Soybean Phospholipid Saturated Acetone Reagent. Take 1 g of powdered sample in a 1000 mL mill bottle, add 1000 mL of acetone, 0 ℃ ~ 5 ℃ ice bath soak 2h, about 15min shaking 1 times. After about 2h, filter with fast filter, the filtrate at 0 ℃ ~ 5 ℃ cold Possession, spare. If the sample is liquid, the powder sample is prepared by acetone extraction. The preparation process is as follows. About 2 g of liquid is weighed with a 50 mL beaker Sample, add 10mL petroleum ether dissolved, add 25mL acetone, precipitate into the glass sand core crucible, with 80mL acetone fraction filter, the remaining The residue is a powdery sample. A.3.3 Instruments and equipment A.3.3.1 Analysis of balance. sensation 0.0001g. A.3.3.2 Glass sand core crucible. G3 (pore size 4.5μm ~ 9μm). A.3.4 Analysis steps The beaker, glass rod and crucible, in 100 ℃ ~ 105 ℃ oven bake to constant weight. Before weighing the sample, first use the glass rod to sample the upper and lower Stir, so that the sample mix evenly. If the sample temperature is low, the viscosity is large, the sample can be tightly sealed, warm water in about 40 ℃, Out, dry the bottle wall, and then stir with a glass rod. Weigh the freshly mixed sample 2.0g (accurate to 0.0005g) in the already constant beaker (even With glass rods). Add 0 ℃ ~ 5 ℃ saturated acetone 30mL, in the ice bath with glass rods to take the combination of mixing and rolling method forced rolling Press the sample, in 2min to make the majority of the oil out of the sample. The solution quickly with a constant weight of the crucible gently pumping, do not put the granular Insoluble matter into the crucible. The inner wall of the crucible was rinsed with 20 mL of acetone at 0 ° C to 5 ° C. In the beaker plus 0 ℃ ~ 5 ℃ saturated C Ketone 20mL, in the ice bath with glass rods with the law to continue rolling the sample 2min ~ 3min, to be insoluble material sinking, the solution through the original crucible Suction filter. The above operation was repeated twice, and all the insoluble matter was crushed into fine powder. After the last 1 milled, take about 0.1mL of clear drops on the glass Quickly evaporate acetone. If there is an oil trail, repeat the acetone milling step until the sample is inspected for oil residue. Stir the insoluble material into the crucible The filter was filtered and washed twice with 0 ° C to 5 ° C saturated acetone. The crucible, glass rod, beaker and insoluble were washed twice (try to remove the insoluble matter Into the crucible), and finally strengthen the filter, remove the remaining acetone. Remove the crucible with a clean gauze and dip a little acetone to wipe the crucible and the beaker outside. The glass rod stirs the crucible sediment. The crucible containing the precipitate and the glass rod and the beaker containing the insoluble residue were immediately placed at 100 ° C ~ 105 ℃ oven drying 30min. After removal, put in a desiccator and cool to room temperature, then weighed. And then dried for 20min, cooling, weighing, Until constant weight. A.3.5 Calculation of results The mass fraction of acetone insoluble matter w is calculated according to formula (A.1) w = m1-m2 m x 100% -w1 (A.1) Where. m1 --- the total mass of crucible, beaker, glass rod and sediment after drying, in grams (g); m2 --- empty crucible, beaker, the total mass of glass rods, in grams (g); w1 --- n-hexane insoluble content,%; m --- sample quality, g. The arithmetic mean of the results of two parallel measurements is the result of the measurement. The absolute difference between the two parallel determinations is not more than 0.5%. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB 1886.238-2016_English be delivered?Answer: Upon your order, we will start to translate GB 1886.238-2016_English as soon as possible, and keep you informed of the progress.
