GBZ/T 300.118-2017 Determination of Toxic Substances in Workplace Air Part 118: Acetic Anhydride, Maleic Anhydride, and Phthalic Anhydride
This standard replaces GBZ/T 160.60-2004 for the determination of toxic substances in workplace air and acid anhydride compounds
This section of GBZ/T 300 specifies the solvent desorption gas chromatography method for acetic anhydride in workplace air, the solution absorption high performance liquid chromatography method for maleic anhydride, and the solvent elution gas chromatography method for phthalic anhydride.
This section is applicable to the detection of concentrations of acetic anhydride, maleic anhydride, and phthalic anhydride in the air of the workplace.
Maleic anhydride, also known as maleic anhydride (MA), abbreviated as maleic anhydride, is the anhydride of maleic acid. It is a colorless or white solid with an acidic taste at room temperature, and its molecular formula is C4H203. It can be used as a raw material for the production of 1,4-butanediol, gamma butyrolactone, tetrahydrofuran, succinic acid, alkyd resin, etc. It is also used in pharmaceuticals and pesticides.
