d66 - Introduction

1,2,3,4,7, (1,2,3,4,7, abbreviated as HxCDD) is an organic pollutant, it belongs to polychlorinated dibenzo-p-dioxins. The following is a description of some of the properties, uses, methods and safety information of HxCDD:

Nature:
- HxCDD is a colorless to white crystalline solid. It is almost insoluble in water at room temperature, but can be dissolved in organic solvents.
- HxCDD has a high degree of stability and durability, it has strong toxicity and carcinogenicity, and cause harm to the environment and organisms.

Use:
-Because HxCDD is highly toxic, it has no practical commercial use. However, it is a common environmental pollutant, usually associated with waste combustion, chemical plant emissions and the use of organic compounds such as pesticides.

Method:
- HxCDD is prepared by reacting chlorine with dibenzophenol and its derivatives at high temperature.

Safety Information:
- HxCDD is a strong carcinogen and nerve poison, which has serious harm to human body and environment.
-exposure to HxCDD in the workplace may cause symptoms of poisoning, including dizziness, nausea, vomiting, and itchy skin.
-Long-term exposure to HxCDD may cause damage to the immune system, reproductive system, and nervous system.
- HxCDD has extremely high environmental toxicity and has a serious impact on biodiversity and biological chains in ecosystems.
-The best way to safely dispose of HxCDD is through incineration or storage through special hazardous waste treatment facilities.
