2,3,3-Trichloroacrylic acid - Introduction
Trichloroacrylic acid is an organic compound with the chemical formula C3Cl3COOH. The following is an introduction to some of its properties, uses, methods and safety information:
Nature:
-Appearance: Colorless to slightly yellow crystal or solid powder at room temperature.
-Solubility: Soluble in water and organic solvents, such as alcohols and ethers.
-Stability: It is relatively stable under regular conditions, but it will decompose when heated, irradiated with ultraviolet light or exposed to strong oxidants.
Use:
-Chemical synthesis: Trichloroacrylic acid can be used to synthesize other organic compounds, such as polymers, chemical reagents and pharmaceutical intermediates.
-Chemical reaction: It can be used as an acid catalyst and reaction intermediate for organic synthesis reactions. For example, it is used as an important ligand for chlorinating agents and acid catalysts.
Method:
trichoroacrylic acid can be prepared by the following methods:
-Chlorination of trichloropropene gives trichloropropionyl chloride, which is then reacted with water to give Trichloroacrylic acid.
-Trichloroacetic acid (Trichloroacetic acid) is obtained by oxidation of trichloroethylene (Trichloroethene), and then Trichloroacrylic acid is obtained by decarboxylation reaction.
Safety Information:
-tricholoroacrylic acid is a corrosive substance that may cause irritation and damage to the eyes, skin and respiratory tract. Wear protective gloves, goggles and respiratory protection when using.
-Avoid contact with strong oxidants, strong acids, ammonia and other substances during storage and handling.
-Use and handle in a well-ventilated place and avoid inhalation, ingestion or contact with skin.
-In the case of accidental leaks, appropriate protective equipment and measures should be taken to avoid entering water sources, drainage systems and groundwater.
Please note that Trichloroacrylic acid is a chemical and must be handled with caution and in accordance with relevant regulations and safe operating procedures.
