A test method for 2,6-di-tert-butyl-4-nitrophenol and study on assessment of potential to phenolic yellowing of textiles products
In the assessment of potential to phenolic yellowing of textiles,testing institutions found that there was a lack of standard reference materials acceptance checking,and there was no test method for 2,6-di-tert-butyl-4-nitrophenol(DTNP).In this paper,the determination of 2,6-di-tert-butyl-4-nitrophenol in phenol yelotation standard card was carried out by liquid chromatography-mass spectrometer.The target analyte has a linear relationship with the peak area response and mass concentration in the concentration range of 0.05～0.4 ug/mL,r=0.9995.The minimum detected concentration is 0.025 ug/mL.The mean relative standard deviation was 2.90％at 0.05 ug/mL concentration.This method can be used for quality control and acceptance of phenol yellowing standard samples,and can also provide data reference for phenol yellowing rating of textile products.
