PCB NO 169 - Introduction
3,3,4,4,5,5-Hexachlorobiphenyl, also known as HCB, is an organic compound with the chemical formula C12H6Cl6. The following is a description of its nature, use, preparation and safety information:
Nature:
-Physical properties: 3,3,4,4, 5,5-hexachlorobiphenyl is a colorless crystal, solid at room temperature. It is insoluble in water but soluble in organic solvents such as methanol, ethanol and ethers.
-Chemical properties: It is a stable compound with high thermal stability. It is not prone to chemical reactions, but can gradually decompose under high temperature and high pressure conditions.
Use:
- 3,3,4,4,5,5-hexachlorobiphenyl was previously widely used as an additive for pesticides and industrial chemicals. It has excellent electrical insulation properties and heat resistance, so it is also used in the manufacture of electronic products and the production of insulating materials.
-Due to the toxicity of 3,3,4,4,5,5-hexachlorobiphenyl and the risk of environmental pollution, its use has been banned or severely restricted. At present, it is mainly used as the research object of environmental pollutants.
Preparation Method:
- 3,3,4,4,5,5-hexachlorobiphenyl is prepared by organic synthesis methods. One common method of preparation is by reacting p-chlorobenzene with cupric chloride in the presence of a reactant. The preparation process needs to be carried out under appropriate conditions, accompanied by waste disposal and environmental protection.
Safety Information:
- 3,3,4,4,5,5-hexachlorobiphenyl is highly toxic and is a persistent organic pollutant (POPs). Long-term exposure or large-scale exposure will pose a serious threat to human health, which may cause neurotoxicity, immunotoxicity and carcinogenicity. Therefore, it is very important to avoid direct contact and ingestion.
-In laboratory and industrial use, strict safety measures are required, including wearing protective gloves, protective clothing and protective glasses. In the preparation, use and handling of 3,3,4,4,5,5-hexachlorobiphenyl, the relevant safety procedures should be strictly observed, and the disposal of waste should be standardized to reduce the risk of environmental pollution.
