Usage

Description

2,5-Cyclohexadien-1-one, 4-[[4-(phenylamino)phenyl]imino]-, reaction products with sodium sulfide (Na2(Sx)) is a navy blue powder that is insoluble in water and moderately soluble in sodium sulfide solution. It exhibits color changes in different chemical environments, turning green-yellow in sodium sulfide solution, green light blue in concentrated sulfuric acid, and dark after dilution and precipitation. In alkaline insurance powder, it shows green light yellow color, which can be restored to its original color and lustre after oxidation. However, it fades in sodium hypochlorite solution and turns black when concentrated sulfuric acid is added.

Uses

Used in Textile Industry:
2,5-Cyclohexadien-1-one, 4-[[4-(phenylamino)phenyl]imino]-, reaction products with sodium sulfide (Na2(Sx)) is used as a dye for cotton, hemp, viscose, and vinylon/cotton blended fabrics. It is known for its acid and alkali resistance, light fastness, fulling, perspiration fastness, and soaping properties, with ratings of moderate to severe according to ISO and AATCC standards.
Used in Leather and Paper Industry:
2,5-Cyclohexadien-1-one, 4-[[4-(phenylamino)phenyl]imino]-, reaction products with sodium sulfide (Na2(Sx)) can also be used for leather and paper dyeing, providing coloration and enhancing the appearance of these materials.

Preparation

4-(4-(Phenylamino)phenylimino)cyclohexa-2,5-dienone with Sodium polysulfide solution at 122 ~ 124 ℃ heating 36 hours, after diluted with air precipitation (BIOS 1155, – 22). This indophenol?by Diphenylamine and 4-Nitrosophenol in sulfuric acid in the condensation, in 116 ~ 117 ℃ reflux get a brilliant color of dye.
