2,2′,3,5,5′,6-PCB - Introduction
PCB No 151 (HCB) is an organic compound with the chemical formula C12H6Cl6. The following is an introduction to the nature, use, formulation and safety information of HCB:
Nature:
1. Appearance: HCB is a colorless to white crystalline solid.
2. Melting point: About 230 ° C.
3. Boiling Point: about 420 ° C.
4. Density: about 2.1 g/cm.
5. Solubility: HCB is insoluble in water at room temperature, but soluble in organic solvents such as alcohols, ethers and ketones.
Use:
1. Pesticide: HCB was once used as an insecticide, but it is no longer widely used, mainly because of its toxicity and persistence.
2. Industrial use: HCB can be used as raw materials for electronics and cosmetics.
Preparation Method:
The preparation of HCB is usually carried out by the chlorination of aromatic hydrocarbons. The specific preparation method can be to replace the hydrogen atoms on the benzene ring with chlorine gas to obtain HCB.
Safety Information:
1. Toxicity: HCB is highly toxic and has potential harm to human body and environment. Long-term exposure may cause damage to the nervous system, liver and kidneys.
2. Environmental impact: HCB is a persistent organic pollutant, which has accumulation and migration to the environment. It may cause long-term pollution to water, soil and organisms.
3. Protective measures: when exposed to HCB, wear protective glasses, gloves and respiratory protective equipment to avoid contact and inhalation. Care should be taken to avoid improper handling and release of HCB and proper disposal.
Please note that due to the toxicity and environmental impact of HCB, and no longer widely used, the handling and disposal of HCB should comply with relevant laws and regulations and safe operating procedures.
