Ultraviolet Absorption Spectra of Phthalic Anhydride and Related Substances. Analytical Method for Naphthalene and 1,4-Naphthoquinone

Quantitative Determination of Maleic Anhydride, Benzoic Acid, Naphthalene, and 1,4-Naphthoquinone in Phthalic Anhydride by Gas Liquid Chromatography.

“…It is often necessary to determine the amount of additives present in finished polystyrene. This has usually been accomplished by spectrophotometric methods such as infrared and ultraviolet adsorption (5,6).…”
