Determination of Solubility of TBOPDA in the Different Concentration of HNO₃ by Gas Chromatography

In this paper, a gas chromatograhic assay for TBOPDA with flame ionization detector (FID) and Porapak-Qs column was used. First, the equal volume of 0.2 mol/L TBOPDA /40% octanol-OK and HNO₃ were shaked for 40 min, then TBOPDA in the liquid phase with methylbenzene was extracted, and last organic phase with gas chromatography was analyzed. Solubility of TBOPDA in the concentration of 1, 2, 3 mol/L HNO₃ is respectively 0.702, 0.723, 0.735 g/L.
