Eryanghuatan Carbon Dioxide CO2 44.01

[124 38 9]

This product should contain no less than 99.5% CO2 (ml/ml).

【 Character 】 This product is a colorless gas; Odorless; The aqueous solution exhibits weak acidic reactions.

This product is soluble in approximately 1 volume of water at atmospheric pressure of 20 ℃.

[Identification] (1) Take this product and put it into Barium hydroxide test solution to generate white precipitate; Precipitation can dissolve in acetic acid and undergo boiling.

(2) This product can extinguish flames.

(3) The infrared absorption spectrum of this product should be consistent with the control spectrum (Figure 1) - Zhi (General Rule 0402).

[Inspection] Acidity: Take 100ml of water, add 0.2ml of Methyl orange indicator solution, mix well, take 50ml separately, place it in two colorimetric tubes A and B, put it in tube B, add 1.0ml of hydrochloric acid titrant (0.01ml/L), and shake well; After passing 1000ml of this product (at a speed of 4000ml per hour) into tube A, the red color should not be darker than that in tube B.

Carbon monoxide is taken from this product and measured using a carbon monoxide detection tube. The content of carbon monoxide should not exceed 10 parts per million.

Phosphine Take this product and measure it with Phosphine detector tube. The content of Phosphine should not exceed 3 parts per million.

Hydrogen sulfide is taken from this product and measured using a hydrogen sulfide detection tube. The content of hydrogen sulfide should not exceed one millionth.

Take this product as the test sample for hydrocarbons; Take a gas with a methane content of 0.0020% (using nitrogen as the diluent) as the reference gas, and perform the gas chromatography test according to General Rule 0521. Use a chromatographic column (0.8m) filled with glass balls × 4mm, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector temperature is 120 ℃. Measure the test sample gas and control gas, inject them into a gas chromatograph, and the peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Measure the test sample gas and control gas, inject them into a gas chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. Calculated using the external standard method to correct peak area, the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
