Exam

peroxide

take this product 10. 0g, put it in 250NTI iodine bottle, immediately add glacial acetic acid-three gas methane (60: 40) 3 0M l, shake to dissolve, add saturated potassium iodide solution 0.5m l, dense plug, shake for 1 min, add water 30ml, with sodium thiosulfate titration solution (0.01mol/L) titration, near the end point, add starch indicator solution 0.5ml, titration was continued until the blue color disappeared and the results of the titration were corrected with a blank test. Consumption of sodium thiosulfate titration solution (0.01mol/L) should not exceed 10.0.

unsaponifiable matter

take this product 5. Add potassium hydroxide ethanol solution (12g of potassium hydroxide, add 10ml of water to dissolve), dilute to 10 0ml with ethanol, shake well,> 50M l, heated to reflux for 1 hour, let cool to 25X: below, move to separatory funnel, wash the Erlenmeyer flask twice with water, 50tnl each time, wash and separate into the funnel, extract with ether for 3 times, 10m l each time; Combine the ether extract, wash the ether extract with water for 3 times, 40m l each time, let stand and layer, discard the water layer; layer B was successively washed with 3% potassium hydroxide solution and water for 3 times, 40m l each time; The ether layer was repeatedly washed with 40ml water until 2 drops of phenolphthalein indicator solution added to the final washing solution did not show red color. The ether extract was transferred to a constant-weight evaporation dish, and the separating funnel was washed with 10ml of ether, and the dish was evaporated with washing solution. The ether was distilled off on a 50°C water bath, and the residue was dissolved with 6mL of acetone, air flow was placed to sweep away acetone. The difference between drying at 105BC and weighing two times in a row should not exceed 1 LG and the unsaponifiable should not exceed 1.0%. Dissolve the residue with 20ml of neutral ethanol, add several drops of phenolphthalein indicator solution, and make sodium hydroxide titration solution with ethanol (0. lm o l/L> titration to pink for 30 seconds does not fade, if consumption of ethanol to sodium hydroxide titration solution (0. lm o l/L) more than 0. 2 m l, the total amount of residue can not be regarded as unsaponifiable weight, the test must be repeated.

cottonseed oil

take 5 m l of this product, place it in a test tube, add 5 m l of 1% sulfur carbon disulfide solution and the isovolumic mixture of pentanol, and place it in a saturated gasification sodium water bath, be careful to heat slowly until the foam stops (carbon disulfide is removed) and continue heating for 15 minutes without redness.

moisture

take this product, with anhydrous methanol-decanol (1> 1) as the solvent, according to the determination of water content (General rule 0832 first method 1), the water content shall not exceed 0 .1%.

Heavy metals

take 4.0g of this product, put it in a 5 0m l porcelain evaporation dish, add sulfuric acid 4 m l, mix well, slowly heat until the sulfuric acid is removed, add 2 tn l of nitric acid and 5 drops of sulfuric acid, after being heated by small fire until the oxidation nitrogen is removed completely, it shall be completely Ashes by burning at 500-6001C, and then cooled. Inspection shall be conducted according to law (General Principles 0821, Law 2), and the content of heavy metals shall not exceed 5 parts per million.

arsenic salt

take this product l. O g, add calcium hydroxide l. O g, mix, add a small amount of water, stir evenly, dry, first burn with small fire to charring, then burn at 500 ~ 600TC to completely Ash, cool, add hydrochloric acid 5M l and water 23ML, according to the law inspection (General Principles 0822 The first law), should comply with the provisions (0. 0002%).

fatty acid composition

take this product 0. lg, put in 50 m l Erlenmeyer flask, add 0. 5M o l/L potassium hydroxide methanol solution 2ml, in 65X: water bath heated reflux 3 0 min, cool, add 15% boron trifluoride methanol solution 2ml, in 65X; Water bath heated reflux 3 0 min, cool, add 4ml heptane, continue heating and refluxing in 65°C water bath for 5 minutes, then cool, add 10ml saturated gasification sodium solution to wash, shake well, let stand to separate layers, and take the upper layer of liquid, wash with water for 3 times, each time 2 m l, take the upper liquid anhydrous sodium sulfate drying as a test solution. According to the test of gas chromatography (General 0521), the bonded polyethylene glycol is used as the stationary liquid, the starting temperature is 2 3 0°C, the temperature is maintained for 1 min, and the temperature is raised to 2 5 0°C at the rate of SeC per minute, for 10 minutes, the temperature of the injection port was 206X:, and the temperature of the detector was 2 70 t. The reference substances of methyl ester, methyl palmitate, methyl palmitate, methyl stearate, methyl oleate, methyl linoleate, methyl linolenic acid, methyl arachidate, N-hexane was added to dissolve and dilute to make each control containing 0. lm g solution, take lUL injection human gas chromatograph, record the chromatogram, the number of theoretical plate according to linoleic acid peak calculation is not less than 5 0 0 0, the separation of each chromatographic peak should meet the requirements. Take the sample solution l UL, inject the gas chromatograph, record the chromatogram. According to the area normalization method, the saturated fatty acid containing less than fourteen carbon in the test article is not more than 0.1%, and the decanoic acid is not more than 0 .2%, palmitic acid should be 9.0% to 13.0%, palmitoleic acid is not greater than 0 .3%, stearic acid should be 3.0% ~ 5.0%, oleic acid should be 17.0% ~ 30.0%, linoleic acid should be 48.0% ~ 58.0%, linolenic acid should be 5.0% ~ 11.0%, arachidic acid is not greater than 1.0%, arachidonic acid is not greater than 1.0%, behenic acid is no more than 1.0%.
