Introduction

Acid Red 80, also known as Red 80, is an organic compound with the chemical name 4-(2-hydroxy-1-naphthalenylazo)-3-nitrobenzenesulfonic acid. The following is an introduction to the properties, uses, preparation methods and safety information of Acid Red 80:

Quality:

- It is a red crystalline powder with good solubility and dyeing properties.

- Acid Red 80 is an acidic solution in water, sensitive to acidic environment, has poor stability, and is susceptible to light and oxidation.

Use:

- Acid Red 80 is widely used in the textile, leather and printing industries as a red dye.

- It can be used to dye textile, silk, cotton, wool and other fiber materials, with good dyeing performance and color fastness.

Method:

- The preparation method of Acid Red 80 is mainly synthesized by azo reaction.

- 2-hydroxy-1-naphthylamine is reacted with 3-nitrobenzene sulfonic acid to synthesize azo compounds.

- The azo compounds are then further acidified and treated to give Acid Red 80.

Safety Information:
