| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | used in the synthesis of pharmaceuticals, pesticides and organic chemicals mainly used as organic solvents, high temperature resistant and corrosion resistant coatings and adhesives can be obtained by copolymerization with ethylene chloride. Or synthetic medicines, pesticides, polymer materials and raw materials for organic chemicals. |
| production method | 1. From perfluoroisobutylene by potassium permanganate oxidation. Perfluoroisobutylene is obtained by cracking tetrafluoroethylene, and after the oxidation reaction is completed, the temperature is reduced to below 30 °c. The obtained product was separated by crude distillation and potassium salt, and about 30% perfluoroacetone hydrate could be obtained at the top of the column, and more than 95% of the product could be obtained by crude distillation. 2. The isomerization of hexafluoropropylene oxide in the presence of Sb2O5 catalyst was carried out at <200 ℃ and 0.103-14.179MPa. |

Hexafluoroacetone - Nature
Open Data Verified Data
non-combustible gas. Boiling point -27. 28 °c. Melting Point -125. 45 °c. Liquid density (23.3 °c) 1.323,(25 °c) 1.318g/mL. The critical pressure is 2.834MPA. On thermal stability, 300 deg C long-term heating, no significant decomposition. Above 550 ° C., the cracking is started, and hexafluoroethane, difluorocarbon, and the like are successively generated.

Hexafluoroacetone - Safety
Open Data Verified Data
This product has moderate toxicity, has a strong stimulating effect on the skin and eyes. TLV (threshold value) 0.1*10-6. Animal experiments showed that rats were exposed to 30 minutes of IC30 = 5.52mg/L. 3 hours of LCo exposure 1. 69mg/L, showing central nervous system inhibition, in the lungs of blood, edema and bleeding; Dog inhalation concentration of 30.6 mg/L 30 minutes of this product is in anesthesia, such as the action time of 45 minutes, one of the two dogs died under the symptoms of collapse (drop in blood pressure), bleeding and edema were seen in the lungs. This product has no carcinogenicity, but has obvious teratogenic effect.
The production equipment should be closed, the workshop should be well ventilated, and the operator should wear protective equipment. If the product touches the skin and eyes, the application of water rinse, severe cases of extended treatment. Storage and transportation with steel cylinder, usually filled to 2 ~ 5MPa, stored in a cool, dry, ventilated place
