Solution was used in the tests did not indicate what is formulated with solvent, it refers to an aqueous solution. A.2 Identification Test The sample 1mg dissolved in 10mL acetonitrile, and observed under ultraviolet light, it can show a strong fluorescence. A.3 Determination of Ethoxyquin A.3.1 Reagents and materials A.3.1.1 glacial acetic acid. A.3.1.2 methyl violet indicator solution. 10g/L. Weigh 1g methyl violet, dissolved in an appropriate amount of glacial acetic acid, into the 100mL flask with ice Acetic acid volume. A.3.1.3 perchloric acid standard titration solution. c (HClO4) = 0.1mol/L. A.3.1.4 acetic anhydride. A.3.2 Analysis step Weigh about 0.2g sample, accurate to 0.0001g, placed in a clean, dry conical flask, 50mL glacial acetic acid to dissolve, plus 1mL of acetic anhydride into the mix, add 2 drops of methyl violet indicator solution, titration with perchloric acid standard solution titration to the green is the end. At the same time a blank test. A.3.3 Calculation Results Ethoxyquin mass fraction w1, according to equation (A.1) Calculated. w1 = (V-V0) × c × M 1000 × m × 100% (A.1) Where. V --- sample consumed perchloric acid standard titration solution volume in milliliters (mL); V0 --- blank test consumption volume perchloric acid standard solution, in milliliters (mL); Concentration c --- perchloric acid standard titration solution, expressed in moles per liter (mol/L); --- Ethoxyquin the M molar mass in grams per mole (g/mol) [M (C14H19NO) = 217.31]; 1000 --- volume conversion factor; M --- the quality of the sample, in grams (g). The arithmetic average of the results of two parallel determination for reporting results. Two parallel determination results is not more than 0.4% absolute difference.

Others can achieve the same degree of separation columns and chromatographic operating conditions Member may also be used. Table A.1 Recommended chromatographic columns and operating conditions Project Parameters Column 5% phenyl - methyl polysiloxane Column column diameter × length × thickness of 30m × 0.32mm × 0.25μm Column temperature/℃ Initial temperature 60 ℃, temperature rising rate of 10.0 ℃/min was raised to 200 ℃, holding 6min, And then at a rate of 20 ℃/min raised to 280 ℃, kept 10min Gasification chamber temperature/℃ 240 Detector temperature/℃ 280 Nitrogen carrier gas Flow rate/(mL/min) 40 A.4.5 Analysis step After the instrument is stable, the number of injection needles standard solution until the adjacent stable than two needle peak area analyzed in the following order. a) amino benzene ether standard solution (A.4.2.4); GB 1886.225-2016 b) the sample solution (A.4.2.5); c) sample solution (A.4.2.5); d) amino benzene ether standard solution (A.4.2.4). Injection volume are 1μL. A.4.6 Calculation Results Press a) → b) → c) → d) the order of injection, each injection peak area ratio f according to equation (A.2) Calculated. f = S1 S2 (A.2) Where. S1 --- for phenetidine peak area; S2 --- internal standard peak area. According to equation (A.2) obtained fa and fd, fb and fc are averaged, respectively, to obtain f1 and f2. Phenetidine quality scores w2, according to equation (A.3) Calculated. w2 = f1 × m1 × w f2 × m2 × 100% (A.3) Where. f1 --- phenetidine standard solution than the average of pairs of phenetidine and the internal standard peak area of; m1 --- quality of phenetidine standards, in units of grams (g); w --- to phenetidine standard mass fraction,%; f2 --- the average of the sample solution and ether ratio of amino benzene internal standard peak area of; m2 --- sample mass, in grams (g). The arithmetic average of the results of two parallel determination for reporting results. Two parallel determination results is not more than the absolute difference between the two measured 6% of the arithmetic mean value. ......
