Applications / Functions of 1,4-Dihydroxyanthraquinone powder
- 1,4-Dihydroxyanthraquinone powder is used as an intermediate in the manufacture of reducing dyes, disperse dyes and reactive dyes.
- Transparent Orange 2G is mainly used for oil colouring.1,4-Dihydroxyanthraquinone CAS 81-64-1 can also be used for colouring all kinds of plastics, resins and their products.
Physicochemical Property of 1,4-Dihydroxyanthraquinone powder
Orange crystals when precipitated from acetic acid. Appropriate amount dissolved in ethanol is red, dissolved in ether is brown and yellow fluorescence, dissolved in caustic soda and ammonia is purple.
Production methodprocess of 1,4-Dihydroxyanthraquinone powder
- Phthalic anhydride and hydroquinone are condensed in concentrated sulphuric acid in the presence of boric acid, then diluted, washed, neutralised, oxidised and press-filtered to obtain 1,4-Dihydroxyanthraquinone Raw Materials .
- Phthalic anhydride and p-chlorophenol were used as raw materials, and the two were condensed, ring-closed, and hydrolysed to obtain the product. After filtration, drying, crushing to get 1,4-Dihydroxyanthraquinone powder .
- Also can be phthalic anhydride and hydroquinone as raw materials, condensation, ring closure to get the product. After filtration, drying, crushing to 1,4-Dihydroxyanthraquinone CAS 81-64-1.
