A derivation method for the specific and sensitive analysis of 3, 5-di-tert-butyl-4-hydroxytoluene (BHT) by gas chromatography has been developed. BHT was treated with ethanolic hydrochloric acid at 95°for 1 hr. The resulting 2-tert-butyl-p-cresol was extracted with benzene and further treated with 2, 4-dinitrofluorobenzene and sodium hydride at 95°for 1 hr to form the electron-capturing ether derivative (DNPE). The reaction was successfully applied to the gas chromatographic determination of a micro-amount of BHT in the range of 0.05-10 μg.
