Description
Trifluoromethyl trifluorovinyl ether is a colorless gas that is heavier than air and can be easily liquefied. It has the potential to cause frostbite upon contact with the liquid due to evaporative cooling and may lead to asphyxiation by displacing air. Additionally, there is a risk of a flame flashing back from the ignition source to the leak source. Prolonged exposure to fire or heat may result in the violent rupture of containers, causing them to rocket.
Uses
Used in Chemical Industry:
Trifluoromethyl trifluorovinyl ether is used as a chemical intermediate for the synthesis of various fluorinated compounds. Its unique properties, such as being heavier than air and easily liquefied, make it suitable for use in the production of specialty chemicals and materials.
Used in Firefighting:
Due to its ability to displace air and potentially cause asphyxiation, trifluoromethyl trifluorovinyl ether can be used in firefighting applications where it can help to smother fires by reducing the oxygen supply. However, caution must be taken to avoid the risk of flash backs and container rupture under certain conditions.
Used in Research and Development:
Trifluoromethyl trifluorovinyl ether's unique properties make it an interesting compound for research and development in various fields, including materials science, chemical engineering, and environmental science. Its potential applications in these areas are still being explored and may lead to new discoveries and innovations.
Used in Safety and Hazardous Material Handling:
Given the potential hazards associated with trifluoromethyl trifluorovinyl ether, such as frostbite, asphyxiation, and the risk of flash backs, it is essential to use this compound in industries that specialize in safety and hazardous material handling. These industries can develop protocols and equipment to safely manage and utilize the compound in various applications.
Air & Water Reactions
Highly flammable.
Reactivity Profile
Trifluoromethyl trifluorovinyl ether oxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979. p.151-154, 164].
Health Hazard
Vapors may cause dizziness or asphyxiation without warning. Some may be irritating if inhaled at high concentrations. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases.
Fire Hazard
EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. CAUTION: Hydrogen (UN1049), Deuterium (UN1957), Hydrogen, refrigerated liquid (UN1966) and Methane (UN1971) are lighter than air and will rise. Hydrogen and Deuterium fires are difficult to detect since they burn with an invisible flame. Use an alternate method of detection (thermal camera, broom handle, etc.) Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
Flammability and Explosibility
Flammable
Check Digit Verification of cas no
The CAS Registry Mumber 1187-93-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1187-93:
(6*1)+(5*1)+(4*8)+(3*7)+(2*9)+(1*3)=85
85 % 10 = 5
So 1187-93-5 is a valid CAS Registry Number.

Methyl hypofluorite (MeOF) reactions with various fluoroolefins
Suzuta, Tetsuya,Abe, Takashi,Sekiya, Akira
, p. 3 - 8 (2003)
The reaction of methyl hypofluorite (MeOF) with certain fluoroolefins, such as CF2=CF2, CF2=CFCF3, CF2=CFOCF3, CF2=CFOMe, CF2=CClF, CF2=CHF, CF2=CH2, CHF=CH2, CF2=CFCF=CF2, occurred in CD3CN or in the presence of NaF. Using neat MeOF in the presence of NaF was a novel method and gave good results. We observed that when more than three fluorine atoms are bonded to the C-C double bond, the addition products were obtained in mostly good yields.
