Analysis of Food Contact Paper by Hydrolysis and ¹⁹ F-NMR

F NMR were used to examine the fluorine content in FCP coated with polymers containing 6:2 FTOH. Hydrolysis facilitated the analysis of the 6:2 FTOH by releasing it from the polymer FCS. Solid-state NMR offered information regarding fluorine content before and after hydrolysis that when combined with the liquid-state analysis allows the assessment of the reaction. Deuterated sodium hydroxide at a 1 M concentration was sufficient to release most of the FTOH from the majority of the FCP samples. The hydrolysis protocol combined with liquid- and solid-state NMR proved to be an efficient tool to comprehensively examine the fluorine content present in FCS and will be useful as the market surveillance continues past the phase-out period.
