Abstract : A previous report (M. L. Adams. An abbreviation of a quantitative infra-red method for nitrocellulose and its application to alkyd-nitrocellulose lacquers. CCL rept. no. 154, AD-432 592) outlines an infrared absorption technique for the measurement of nitrocellulose in lacquers. The present report utilizes this value for the nitrocellulose content in proposing an infrared absorbance ratio method for the measurement of isophthalic acid present in these lacquers. The determination is carried out on solvent-free films of isolated vehicles and compares the ratio of isophthalic acid to nitrocellulose. (Author)
