Significance and Use
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.
1.1 This 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.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Sections 6 and 7.
1.4 Review the current MSDS for detailed information concerning toxicity, first aid procedures, and safety precautions.
