Abstract:
An efficient method for the determination of p-tert-butylcatechol (TBC) in styrene monomer by gas chromatography/mass spectrometry (GC/MS) has been established. The sample was injected directly, and separated by gas chromatography with capillary column (HP-1, 30 m x 0.32 mm i.d. x 0.25 micron), then determined by a mass-spectrometer with electron impact (EI) at selected ion monitoring (SIM) mode. There was a good linear relationship within the range of 5 mg/kg-50 mg/kg (r2 = 0.9987). Compared with the colorimetric determination by a spectrophotometer (ASTM D4590), the method was proved to be fast and accurate.
