C.I. Acid Red 97, disodium salt (8CI) - Introduction
Acid red 97 is a chemical dye, also known as methyl orange. It is a red crystalline solid, soluble in water and alcohol. The following is an introduction to the nature, use, formulation and safety information of acid red 97:
Nature:
-Appearance: Red crystalline solid
-Solubility: Soluble in water and alcohol
- pH range: it shows red in acidic medium, but gradually turns yellow under neutral or alkaline conditions
Use:
- acid red 97 is mainly used as an organic dye, which can be used in textile, leather, plastic, ink, paint and pigment ink industries.
-It can also be used for stains and fluorescent markers in cosmetics.
Method:
- acid red 97 is usually prepared by reducing the dinitrate of methyl orange.
-In the preparation process, methyl orange dinitrate is first reacted with sodium nitrite to obtain methylamino benzylidene orange. Then it is reacted with sulfuric acid and acidified with hydrochloric acid to obtain acid red 97.
Safety Information:
- acid red 97 is relatively safe under normal conditions of use and storage.
-As a chemical substance, use it in accordance with laboratory safety procedures and wear appropriate personal protective equipment, such as gloves and glasses.
-Avoid contact with strong oxidants to prevent dangerous reactions.
- acid red 97 may be irritating to the eyes and skin, so rinse with water immediately after contact and seek medical help.
