| use | reduced bordeaux 2R is suitable for printing and dyeing cotton cloth and is also used as an organic pigment. |
| production method | method 1: treat reduced red GG (Vat Red 14) with ethanol and potassium hydroxide, filter, evaporate ethanol, and acidify. Method 2: The salt of hydrochloride, sulfonate or hydrobromic acid of Dahong GG was reduced by fractional crystallization from organic solvent. Or the salt obtained by treating it with a strong organic acid. Method 3: Treatment with aluminum chloride or zinc chloride to reduce Dahong GG with or without solvent. The product is then crystallized in stages. For details of operation examples, please refer to Restore Orange GR (C.I.Vat Orange 7). |
