| Use | reduced red GG can be used for cotton dyeing and printing, with general affinity and good levelness, but it is not suitable for dyeing silk and wool. Its color light is yellow than the reduced Red R, but not the reduced red GGN is bright, so it is used less. |
| production method | Method 1: heating O-Phenylenediamine and 1,4,5,8-naphthalenetetracarboxylic acid mixture (when glacial acetic acid is used as the solvent, the product has a larger proportion of trans isomer). Method 2: heating 1,4,5, 8-naphthalenetetracarboxylic acid with O-nitroaniline, reducing the nitro group and cyclizing. Method 3: heating N,N'-diaryl-1, 4,5, 8-naphthalenetetra-diimide with O-phenylenediamine. Examples of operations are detailed in the reduction of Brilliant Orange GR (C.I.Vat Orange 7). |
