Table 1 Sensory requirements Project requires test methods Color White State lamellae Take the right amount of sample is placed in a clean, dry white porcelain dish, in Observe the color and condition of natural light 3.2 Physical and Chemical Indicators Physical and chemical indicators should be consistent with the provisions of Table 2. Table 2. Physical and chemical indicators Item Index Test Method Dilauryl thiodipropionate ester (C30H58O4S) content, w /% 99.0 ~ 100.5 Appendix A A.3 Acidity (thiodipropionic acid), w /% ≤ 0.2 Appendix A A.4 Freezing point/℃ ≥ 40 SN/T 0801.17 Lead (Pb)/(mg/kg) ≤ 10 GB 5009.12Appendix ATesting method A.1 General Provisions This standard reagents and water in the absence of other specified requirements, refer to the three water analytical reagent and GB/T 6682 regulations. Reagent The standard solution, standard solution for measuring impurities, formulations and products, did not indicate when the other requirements according to GB/T 601, GB/T 602, GB/T 603 provisions of the preparation. Solution was used in the tests did not indicate what is formulated with solvent, it refers to an aqueous solution. A.2 Identification Test Solubility. soluble in most organic solvents, insoluble in water. A.3 Determination of dilauryl thiodipropionate ester (C30H58O4S) Content 700mg accurately weighed sample placed in 250mL conical flask, 100mL of acetic acid and 50mL of ethanol. At about 40 ℃ Article Lower heating element mixture until dissolved sample. Then add 3mL hydrochloric acid and 4 drops of test solution set ethoxy Ke Yi (50mg of ethoxy Ke Yi set dissolved in 25mL water and 25mL ethanol mixture, add 3 drops of hydrochloric acid, stirring, if necessary, can be filtered to give a clear liquid), Li Namely with 0.05mol/L bromine solution titration. Until after the end point is reached when the (pink), then add 4 drops of the above indicator solution and continue titration to change from red As a pale yellow. At the same time carry out a blank test and make the necessary corrections. 0.05mol/L solution of bromine 25.74mgC30H58O4S equivalent per ml. Minus is C30H58O4S in the "determination of acidity" value (A.4) measured in thiodipropionic acid content and multiplied by 2.89, the difference between content. A.4 Acidity (thiodipropionic acid) Determination Accurately weigh 2g sample placed in 250mL Erlenmeyer flask was added a mixture of 1 part 50mL of methanol and 3 parts benzene dubbed dissolved After the mixed solution was added 5 drops of phenolphthalein solution, then 0.1mol/L potassium hydroxide ethanol solution titrated. Per milliliter 0.1mol/L potassium acetate Alcohol solution 8.91mg3,3'- thiodipropionic acid equivalent. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB 1886.79-2015_English be delivered?Answer: Upon your order, we will start to translate GB 1886.79-2015_English as soon as possible, and keep you informed of the progress.
