A novel, one-pot method for synthesizing picric acid (2,4,6-trinitrophenol) was previously reported by our group, in which the 4-hydroxyphenylglycine was converted to picric acid in a HNO3/H2O system via the formation of 4-hydroxybenzaldehyde. Although the mechanism for the conversion of 4-hydroxyphenylglycine to 4-hydroxybenzaldehyde was reported in the literature, the formation process of picric acid from 4-hydroxybenzaldehyde remained unclear. In order to establish the reaction mechanism of the formation of picric acid from 4-hydroxybenzaldehyde in the HNO3/H2O system, the same reaction condition was applied to 4-hydroxybenzaldehyde and 4-hydroxybenzoic acid, and the resulting intermediates were identified from each reaction. Intermediates were detected by electrospray ionization mass spectrometry (ESI-MS), and compared with authentic samples. The mass spectra of each reaction and the detailed procedure will be discussed.
