Description
Hexafluoropropylene oxide (HFPO) is a colorless, odorless gas that is shipped as a liquefied gas under its vapor pressure. It is an important intermediate in the production of organic fluorine materials and is known for its potential to cause frostbite upon contact with the liquid and asphyxiation due to the displacement of air by its heavier-than-air vapors. Prolonged exposure to heat or fire may cause the container to rupture violently.
Uses
Used in the Chemical Industry:
Hexafluoropropylene oxide is used as an intermediate for the production of high-quality fluorinated compounds, making it a crucial component in the synthesis of various chemicals.
Used in the Manufacturing of Fluorinated Compounds:
HFPO is used as a key component in the creation of perfluor-vinyl ether (PPVE, PSVE, PFVE, PMVE), which is essential for the development of advanced materials with unique properties.
Used in the Production of Fluorinated Surfactants:
Hexafluoropropylene oxide serves as the monomer for fluorinated surfactants, which are essential in various industrial applications due to their unique properties, such as high surface activity and stability.
Used in the Creation of Fluorinated Ether Oil:
HFPO is also utilized as a monomer in the production of fluorinated ether oil, which has specific applications in the field of lubrication and other specialized uses.
Reactivity Profile
Hexafluoropropylene oxide is a chlorinated epoxide. Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Health Hazard
Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard
Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 428-59-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 428-59:
(5*4)+(4*2)+(3*8)+(2*5)+(1*9)=71
71 % 10 = 1
So 428-59-1 is a valid CAS Registry Number.

Paragraph 0028-0029, (2017/03/18)
The invention discloses a preparation method for hexafluoropropylene oxide. Hexafluoropropylene is used for preparing hexafluoropropylene oxide through a molecular oxygen liquid-phase oxidation method. A hexafluoropropylene solvent used in the molecular oxygen liquid-phase oxidation method is mixture of perfluoropolyethers and fluorocarbon, and a metallic oxide catalyst is added in a reaction process of the molecular oxygen liquid-phase oxidation method. The preparation method has the advantages that the metallic oxide catalyst is added so that temperature required by a reaction is reduced, solubility of hexafluoropropylene in the solvent is greatly increased, and reaction selectivity is improved.
