AN INFRARED ABSORBANCE RATIO METHOD FOR THE DETERMINATION OF PHTHALIC ANHYDRIDE IN ALKYDNITROCELLULOSE LACQUERS.
Abstract
A rapid quantitative method for the determination of the phthalic anhydride content in phthalic alkydnitrocellulose lacquers is described which uses an infrared absorbance ratio technique applied to solvent free films of isolated vehicles. The method is dependent upon the previously determined nitrocellulose concentration. The potential extension of this principle to the determination of the phthalic anhydride content in enamels is discussed and illustrated. (Author)
