Proton NMR Studies of Supported Titanium Catalyst for Quantification of Incorporated Internal Electron Donor

[摘要] Proton NMR method developed for quantification of internal donor incorporated in supported titanium catalyst. 1,1,2,2-tetrachloroethane was used as internal standard for quantification. The calibration curve was prepared and found linear for the desired range. This method was demonstrated for quantification of diisobutyl phthalate in catalyst. Method was resulted in good quantitative estimation of organic species in catalyst, which makes FT-NMR as an alternate analytical tools for quantitative and qualitative analysis.
