Benzothiazole, 2,7-dichloro- (7CI,8CI,9CI) - Introduction
2,7-Dichlorobenzothiazole(2,7-Dichlorobenzothiazole) is an organic compound with the chemical formula C7H3Cl2NS. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 2,7-Dichlorobenzothiazole is a white crystalline solid.
-Solubility: It is more soluble in organic solvents (such as ethanol, acetone and dichloromethane), insoluble in water.
-Melting point: Its melting point is about 141-145 degrees Celsius.
Use:
-Rubber accelerator: 2,7-Dichlorobenzothiazole can be used as an important rubber accelerator, which can promote the vulcanization reaction, increase the vulcanization speed of rubber and improve the vulcanization performance.
-Fungicide: It can also be used as a fungicide in textiles, coatings and adhesives to inhibit the growth of molds and fungi.
Preparation Method:
The preparation method of 2,7-Dichlorobenzothiazole mainly includes the following steps:
1. Benzothiazole-2-sulfuric acid is used as raw material to obtain 2,-sulfuric acid by reacting with chlorine.
2. React 2,-sulfuric acid with caustic soda to desulfurize it to generate 2,7-Dichlorobenzothiazole.
Safety Information:
- 2,7-Dichlorobenzothiazole is irritating to the eyes, skin and respiratory tract and may cause eye and skin damage.
-Avoid inhalation of dust or contact with skin and eyes, and wear protective gloves, goggles and masks when necessary.
-In case of accidental contact, immediately flush the affected area with plenty of water and seek medical help.
-Avoid contact with organics and strong oxidants during storage and handling.
-Waste should be disposed of in accordance with local regulations.
