High Performance Liquid Chromatographic Analysis of Polymerization Inhibitors in Acrylic Monomers

Abstract

High performance liquid chromatographic methods are described which provide for the quantitative determination of p-hydroquinone in acrolein and p-monomethyl ether of hydroquinone in the ethyl, n-butyl, iso-butyl, and 2-ethylhexyl esters of acrylic acid. The procedures are fast, precise, and applicable to industrial process analyses.
