High quality Pyrogallol 87-66-1

Production methods

1. Add the gallic acid and water in the autoclave, in 200-210 ℃ decarboxylation 0.5 h, the decoloring, filtering, evaporation was finished, or refined by vacuum distillation.

2. Using an organic alkaline compound as the catalyst, the control temperature was 18 under normal pressure.

Removing hydroxyl response: 0 ~ 190 ℃, when no longer gives off carbon dioxide gas in the reactants, the reaction has reached the end. The results showed that the coking properties were purified by vacuum distillation and vacuum distillation. …

use
