Uses of Hexachloroacetone: It is mainly used as a pesticide. For the use of hexachloroacetone in the preparation of a novel insect repellent see Perkow reaction. What's more, it can react with 4-methyl-aniline to get 2,2,2-trichloro-N-p-tolyl-acetamide. This reaction needs solvent CHCl3 by heating. The reaction time is 3 hours. The yield is 78%.
When you are using this chemical, please be cautious about it as the following:
It is not only harmful if swallowed, but also toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. So people should avoid contact with skin and eyes. Avoid release to the environment. Refer to special instructions / safety data sheets.
People can use the following data to convert to the molecule structure.
