Scope

This standard specifies the spectrophotometric method for the determination of p-hydroxyanisole (MEHQ) content in acrylonitrile for industrial use. This standard applies to industrial acrylonitrile samples with p-hydroxyanisole content greater than 0.0005% (m/m). Note: All impurities that absorb at 295nm will interfere with the determination. Experience shows that impurities that absorb at this wavelength may be produced in acrylonitrile that has exceeded the storage guarantee period. Therefore, this standard is only applicable to industries whose chromaticity specifications meet the specifications. Use acrylonitrile.
