説明

A gas liquid chromatography (GLC) method was developed for the determination of tetrakis-[methylene-3-(3′, 5′-di-tert-butyl-4′-hydroxyphenyl) propionate] methane, known as Irganox 1010, a high-molecular phenolic antioxidant in polyethylene food packaging films.<br>Direct analysis by GLC is inappropriate for Irganox 1010 because of the high molecular weight. Irganox 1010 was therefore converted to methyl (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate by saponification with potassium hydroxide and then determined by GLC. The product was identified by GLC-MS.<br>The results of the analysis of Irganox 1010 in polyethylene food packaging films by the present method were compared with the results of high performance liquid chromatography (HPLC) for the same samples. The results of the two methods agreed well, and the coefficients of variation in the GLC and HPLC methods were found to be 2.9% and 3.2%, respectively.
