Причина отменыThis test method covers the determination of the impurities in, and the purity of, acrylonitrile by flame ionization detector gas chromatography. It is applicable to acrylonitrile in the range of 99 to 100 % purity.

Formerly under the jurisdiction of Committee E15 on Industrial and Specialty Chemicals, this test method was withdrawn in January 2016 in accordance with Section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

This test method is designed to obtain acrylonitrile purity on the basis of impurities normally present in acrylonitrile and may be useful for final product inspection and process control.

This test method will measure the following impurities: acetone, acrolein, acetonitrile, and acetaldehyde. It also will allow calibration of other impurities including benzene, methacrylonitrile, oxazole, propionitrile, cis-crotononitrile, trans-crotononitrile, and others where specific impurity standards are available.
