1,2,3-TRICHLORONAPHTHALENE - Introduction
1,2,3-Trichloronaphthalene (1,2,3-Trichloronaphthalene) is an organic compound formed by replacing the naphthalene molecule with three chlorine atoms. It is a yellow crystal with an odor similar to naphthalene. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Yellow crystal
-Molecular formula: C10H5Cl
-Molecular weight: 233.51g/mol
-melting point: 98-101 ℃
-Boiling point: 386-387 ℃
-Solubility: Insoluble in water, soluble in organic solvents such as ethanol and ether
Use:
- 1,2, 3-trichloronaphthalene is commonly used as a raw material for organic synthesis and for the synthesis of other compounds.
-It is also used as an intermediate in the manufacture of naphthol resins, which are widely used in coatings, adhesives and plastics.
- 1,2, 3-trichloronaphthalene can also be used as an organic reagent, for example, in organic reactions and catalyst synthesis processes.
Preparation Method:
A common synthesis method of -1,2, 3-trichloronaphthalene is obtained by reacting 1,2,3,4-tetrachloronaphthalene with chlorosulfuric acid. The specific steps include dissolving tetrachloronaphthalene in methylene chloride and then slowly adding chlorosulfuric acid dropwise. The final product was purified by crystallization to give 1,2, 3-trichloronaphthalene.
Safety Information:
- 1,2, 3-trichloronaphthalene is not easy to burn under normal conditions, but may release toxic hydrogen chloride gas when heated.
-This compound is irritating to the eyes and respiratory tract, so wear protective glasses and masks when working.
-Avoid contact with oxidizing agents, strong acids or strong bases during storage and handling.
-If you come into contact with the skin, rinse immediately with plenty of water and seek medical help.
