Characterization of Brominated Vegetable Oils by Normal and Reversed Phase Liquid Chromatography

Abstract

Brominated vegetable oils are characterized by normal and reversed phase chromatography using UV absorbance detection at 220 nm. A series of seven brominated vegetable oil preparations are transesterified using acid methanolysis and the resulting dibromo-, tetrabromo- and hexabromostearate components quantitated by HPLC. The identification of the oils compare favorably with results obtained by gas chromatography.
