Appendix A

Testing method A.1 Safety Tips Reagents The standard test methods used for toxic or corrosive, the operation should be careful! As splashed on the skin should stand That is rinsed with water, severe cases should be treated immediately. A.2 General Provisions Unless otherwise indicated in the analysis using only recognized as analytical reagents and GB/T 6682 stipulated three water. Test Methods The standard titration solution, impurity measurement standard solution, preparations and products, did not indicate when the other requirements, according to GB/T 601, GB/T 602 and 603 of the regulations prepared GB/T ; the solution when the solvent is not specified, refer to the aqueous solution. A.3 Identification Test A.3.1 microscopy Without pasting process to keep the grain structure octenyl succinic aluminum starch can be directly observed and verified starch particle shape through the microscope, Size and character. Under polarized light microscope, it can be observed the typical birefringence. A.3.2 iodine staining 1 g of the sample was added 20 mL of water were suspended, several drops of iodine solution, the color should range from deep blue to reddish brown. A.3.3 copper reduction A.3.3.1 formulated alkaline tartrate copper test solution A.3.3.1.1 Solution A. Copper Sulfate (CuSO4 · 5H2O) 34.66 g, should be no weathering or moisture absorption phenomenon, dissolved in water volume to 500 mL. The solution was stored in a small sealed container. A.3.3.1.2 Solution B. take potassium sodium tartrate (KNaC4H4O6 · 4H2O) 173 g sodium hydroxide 50 g, dissolved in water volume to 500 mL. The solution was stored in a small container and alkali corrosion. A.3.3.1.3 solutions A and B mixed in equal volumes, to obtain an alkaline tartrate copper test solution. A.3.3.2 analysis step Weigh the sample 2.5 g, placed in a flask, 0.82 mol/L hydrochloric acid solution of 10 mL of water and 70 mL, mixing, boiling water bath Was refluxed for 3 h, cooled. Take 0.5 mL solution was cooled, added 5 mL hot alkaline copper tartrate solution, a large amount of red precipitate. A.4 Determination of octenyl succinic group A.4.1 Principle The samples were acidified, washed, base titration. Content octenyl succinic acid group may be calculated based on alkali consumption. A.4.2 Reagents and materials A.4.2.1 isopropanol. A.4.2.2 hydrochloric acid. A.4.2.3 sodium hydroxide. A.4.2.4 silver nitrate. A.4.2.5 isopropanol solution.
