Nuclear magnetic resonance method for the quantitative determination for the plasticizers in cellulose acetate filter rods
Research Laboratories, Tennessee Eastman Company, Division of Eastman Kodak Company, Kingsport, Tennessee USA
A rapid quantitative nuclear magnetic resonance (NMR) method was developed for the analysis of plasticizer mixtures in cellulose acetate filter rods. Five 20-mm rods were extracted into 25 ml CCl4 with 0.4% trifluoracetic acid containing benzene as...
