Foreword
This standard replaces GB/T 6022-1999 "on the industrial use of liquid oxygen in the gas phase butadiene was determined by gas chromatography."
This standard and GB/T 6022-1999 compared to the main changes are as follows.
--- The name was changed to "industrial use - Determination of butadiene vapor liquid oxygen";
--- Increasing the film covering the battery with electrochemical measuring liquid butadiene gas phase oxygen content;
--- Increasing the flow chart 3.5.2 Gas Chromatography;
It changed to 25 ℃ ~ 50 ℃ --- 3.5.3 in the column temperature increased from 15 ℃ ~ 25 ℃;
--- Emboldened original standard gas to argon, nitrogen or argon;
Sampling methods --- butadiene was revised to gaseous oxygen method GB/T 6681 stipulated.
The standard proposed by China Petroleum and Chemical Corporation.
This standard by the National Standardization Technical Committee Petrochemical Chemical Technical Committee (SAC/TC63/SC4) centralized.
This standard drafting units. China Sinopec Yangzi Petrochemical Company Limited.
The main drafters of this standard. SHI Chun Bao, Lu Haiping.
This standard replaces the previous standard release case. GB/T 6022-1999.
Industrial liquid butadiene gas phase oxygen measurement
1 Scope
1.1 standard specifies the determination of industrial liquid butadiene gas phase oxygen content by gas chromatography and thin film covering the battery electrochemistry, gas
Determination of the range of 100mL/m3 ~ 5000mL/m3, covered with a thin film battery with electrochemical measurement range of 1mL/m3 ~
5000mL/m3.
1.2 This standard does not explain all of the safety issues associated with use. Therefore, the user has the responsibility to take appropriate safety and health measures
Facilities, to ensure compliance with the provisions of the relevant national regulations.

3 Gas Chromatography
3.1 Summary of Method
Gas sample through the sampling device into the chromatograph, and a carrier gas into the pre-column, the hydrocarbon components are pre-column adsorption, pre-cleaning
Separation column, the hydrocarbon components vented. Remaining separated components into the separation column, a detector with a thermal conductivity detector. Because oxygen at ambient temperature and in argon
Separation column is not isolated, and therefore the use of argon as a carrier gas, argon in the sample is not generated in response to the thermal conductivity cell. Oxygen peaks obtained surface
Compared with the product of the oxygen peak area obtained from the standard sample, thereby determining the oxygen content in the sample.
3.2 Reagents and materials
3.2.1 Carrier gas
Argon. purity of not less than 99.99% (volume fraction), the oxygen content of not more than 0.002% (volume fraction), free of organic impurities, water and Second
Carbon monoxide.
3.2.2 Preparation of standard sample gas
Nitrogen or argon. purity not less than 99.999% (volume fraction), an oxygen content of not more than 2mL/m3.
Oxygen. purity of not less than 99.99% (volume fraction).
3.2.3 Standard Series Gas Oxygen. The oxygen content was 50mL/m3 ~ 5000mL/m3, emboldened as nitrogen or argon (3.2.2).
3.2.4 stationary phase
Activated carbon (chromatography). diameter of 0.17mm ~ 0.25mm (60 mesh to 80 mesh);
5A molecular sieve (chromatography). diameter of 0.17mm ~ 0.25mm (60 mesh to 80 mesh).
3.3 instruments and equipment
3.3.1 Gas chromatograph. a quantitative gas injection device, cleaning device and a thermal conductivity detector gas chromatograph, the instrument of this standard to
Produces a given peak operating conditions is high, at least two times greater than the noise of the instrument.
3.3.2 Quantitative tubes. 1mL or 5mL.
3.3.3 pre-separation column
Stationary phase. activated carbon (3.2.4);
