General description

Ethylvanillin (3-Ethoxy-4-hydroxybenzaldehyde) is an artificial additive for improving taste. It chemiluminesces by reacting with potassium permanganate in sulphuric or polyphosphoric acid media.

Application

Ethylvanillin (3-Ethoxy-4-hydroxybenzaldehyde) was used as an internal standard in the determination of phenolic compounds obtained from (alkaline) CuO-based oxidation of humic acid.

Vanillin, ethylvanillin and 4-hydroxy-3-methoxy-benzylalcohol have been found to chemiluminesce by the action of potassium permanganate in sulphuric or polyphosphoric acid media. Both acid media have been compared and sulphuric acid allows the sensitive determination of 0.15-10.0, 0.010-1.0 and 0.0030-0.30microg mL(-1)

Operational parameters like migration time, temperature, voltage, composition of background electrolyte and content of organic modifier were optimized in CZE for the determination of lignin-like phenolic compounds. The applied background electrolyte buffer consisted of a Na(2)B(4)O(7), KH(2)PO(4) aqueous solution, pH
