Wash the ether layer with 3% hydrooxidation solution and water 3 times, each time 40m; Then 40ml water was used to reverse wash the ether layer until 2 drops of phenolphthalein indicator solution was added to the final lotion, which did not show red color. Li removed the diethyl ether extract to the evaporation dish with constant weight, washed with diethyl ether 10ml and divided into funnel, wash the liquid into the evaporation dish, put 5(TC water bath to steam the ether, dissolve the residue with acetone 6ml, put the air flow to remove acetone. Dry at 105°C until the difference between two consecutive weighings does not exceed LMG, and the unsaponified matter should not exceed 1.5%. The residue was dissolved in 20ml of neutral ethanol, a few drops of phenolphthalein indicator solution were added, and the residue was dissolved in b

The alcohol sodium hydroxide titration solution (0.lmol/L) is titrated to pink color for 30 seconds without fading. If more than 0.2 ml of the alcohol sodium hydroxide titration solution (O.lmol/L) is consumed, the total amount of residue cannot be regarded as the weight of unsaponified matter and the test must be repeated.

Alkaline impurities

Add 10ml of newly distilled acetone, 0.3ml of water and 1 drop of 0.04% bromophanol blue ethanol solution to the test tube, adjust to neutral with O.lmol /L hydrochloric acid solution or O.lmol /L sodium hydroxide solution, add 10ml of this product, shake fully and then stand. Titration with hydrochloric acid titration solution (O.Omol /L) until the upper liquid appears yellow, the consumption of hydrochloric acid titration solution (0.01mol/L) should not exceed 0.lml.

Cottonseed oil

Take 5ml of this product, put it in a test tube, add 5ml of 1% sulfur carbon disulfide solution and equal volume mixture of amyl alcohol, put it in a saturated sodium water bath, pay attention to slowly heating until the foam stops (remove the carbon disulfide), continue heating for 15 minutes, it should not show red.

Sesame oil

Take 10ml of this product, add 10ml of hydrochloric acid, add new furfural ethanol solution (1-50)0.lml, shake vigorously for 15 seconds, the acid layer should not appear pink to dark red color. If there is color, add 10ml water, shake vigorously again, the color of the acid layer should disappear.

By gas chromatography

Method (General 0521) test. The initial temperature was 230°C for 11 minutes using bonded polyethylene glycol as the fixative, rising to 250°C at a rate of 5-C per minute for 10 minutes. The inlet temperature was 260 °C and the detector temperature was 270°C. Methyl palmitate were taken, palm methyl oleate, methyl stearate, methyl oleate, methyl linoleic acid and linolenic acid methyl ester, arachidic acid methyl ester, 20 carbon olefine acid methyl ester, mountain do acid methyl ester and 24 alkanes acid methyl ester reference substance, with n-hexane made every LML contain a suitable amount of dissolved the reference substance of each 0. Lm g solution, 1, u1 note sentiment chromatograph, record chromatograph chart, The number of theoretical plates should not be less than 10000 according to the peak of methyl oleate, and the separation degree of each chromatographic peak should meet the requirements. The sample solution 1U1 was injected into the mass chromatograph, and the chromatogram was recorded.
