WebAbstractα-Veratrylindanones were obtained by reaction of α-veratrylcinnamic acid with veratrole in polyphosphoric acid (PPA). A method for the synthesis of indeno-2-benzopyrylium salts based on acylation of the indanones with the free acids and their anhydrides was developed. It was shown that indeno-2-benzopyrylium salts can be … In aqueous solution phosphoric acid behaves as a triprotic acid. H3PO4 ⇌ H2PO−4 + H , pKa1 = 2.14 H2PO−4 ⇌ HPO2−4 + H , pKa2 = 7.20 HPO2−4 ⇌ PO3−4 + H , pKa3 = 12.37 The difference between successive pKa values is sufficiently large so that salts of either monohydrogen phosphate, HPO2−4 or dihydrogen phosphate, H2PO−4, can be prepared from a … gree ac timer setting
