对苯偶氮苯甲醚,对甲氧基偶氮苯 - Introduction
4-methoxyazobenzene(4-methoxyazobenzene) is an organic compound with the chemical formula C13H11N3O. The following is a description of the nature, use, preparation and safety information of the substance:
Nature:
-Appearance: 4-methoxyazobenzene is a red crystal powder.
-Melting point: About 143-145 degrees Celsius.
-Solubility: Soluble in organic solvents such as ethanol, dimethylformamide, etc., difficult to dissolve in water.
Use:
-Dye: 4-methoxyazobenzene can be used as a dye and has a wide range of applications in the textile, ink, plastic and coating industries.
-Photosensitive material: This substance can change the color through photosensitive reaction, so it is used in photosensitive materials in devices such as displays, optical switches and optical storage.
Method:
4-methoxyazobenzene can be synthesized by the following steps:
1. Aniline and anhydrous hydrochloric acid reaction to generate aniline salt.
2. Reacting aniline salt with Nitro naphtha to form diaryl amine.
3. React diarylamine with azo salt to generate 4-methoxyazobenzene under alkaline conditions.
Safety Information:
- 4-methoxyazobenzene may be irritating to the skin, eyes and respiratory tract and direct contact should be avoided.
-Wear protective gloves, goggles and protective clothing when handling the substance.
-Avoid contact with oxidants during storage, and store in a dark and dry place.
