Title: Analysis of Impurities in the 4-Bromophthalic Anhydride Products by High Performance Liquid Chromatography
Abstract: An analysis method based on High Performance Liquid Chromatography is developed for the composition determining of theproducts of 4-bromophthalic anhydride process.The main components are as follows:phthalic anhydride,phthalic acid,4-bromophthalic acid,4-bromophthalic anhydride.The column is Agillent TC-C18 at 25℃,acetic acid aqueous solution and methanol are two mobile phases using elution and the wave length of ultraviolet detection is 236nm,overall analysis on the four main components of the product can be finished in 30min with one sample transfusion.
