Standard Test Method for Analysis of Bisphenol A (4,4`-Isopropylidenediphenol) by High Performance Liquid Chromatography

Importancia y uso:

4.1 Bisphenol A is used for production of polycarbonate or epoxy resin. The presence of impurities in bisphenol A is undesirable because they may slow down the polymerization and be impurities in the final product.

4.2 Determination of the trace impurities, such as isomer of bisphenol A and the unreacted raw material, is often required. This test method is suitable for setting specifications and for using as an internal quality control where these products are produced or used.

4.3 Purity is commonly reported by subtracting the determined expected impurities and water from 100 %. However, a HPLC analysis cannot determine absolute purity if unknown components are contained within the material being examined.
