Tartrazine synthesis
WebMay 15, 2024 · Tartrazine is highly soluble in water as the trisodium salt, though the free acid is very insoluble in water. Physical. Tartrazine is an odorless yellow solid compound, soluble in water and glycols. Some sources claim its color is either yellow-orange or (dark) orange, even red, though this is most likely from air oxidation or other impurities. WebThe tartrazine-induced amorphous aggregation process is kinetically very fast, and aggregation occurred without the formation of a nucleus. These results proposed that the electrostatic interaction is responsible for tartrazine-induced amorphous aggregation. This study may help in the understanding of mechanistic insight of aggregation by ...
