Formaldehyde in Alcoholic Beverages: Large Chemical Survey Using Purpald Screening Followed by Chromotropic Acid Spectrophotometry with Multivariate Curve Resolution
Figure 6
Calculated UV-VIS spectra of the possible reaction products of the chromotropic acid-formaldehyde reaction. Structure (1): monocationic dibenzoxanthylium structure; structure (2): para,para-quinoidal structure (for structural formulae see Figure 1).
