Usage

General Description

2,2,2-Trifluoroethyl trifluoromethyl ether, also known by the chemical formula C4F9O, is a colorless, flammable, and volatile liquid compound used as a solvent, refrigerant, and propellant in various industrial applications. It has a high boiling point and low surface tension, making it useful in the production of aerosol propellants and refrigerants. It is also a valuable chemical intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. However, it is important to handle this compound with caution as it is harmful if swallowed or inhaled, and may cause skin and eye irritation upon contact. Additionally, it is a potential environmental pollutant and should be properly managed to prevent adverse effects on the ecosystem.

Practical preparation of potentially anesthetic fluorinated ethyl methyl ethers by means of bromine trifluoride and other methods

Synthetic methods, especially those that use bromine trifluoride as a fluorinating agent, are described for the preparation of a number of fluorinated ethyl methyl ethers in good yield and high purity. In all cases, medium-scale syntheses (8-22g) of potentially anesthetic compounds have been accomplished. The compounds are of sufficient purity (>99%) for biological evaluation.

Compositions of a hydrofluoroether and a hydrofluorocarbon

This invention relates to compositions that include at least one fluoroether and at least one hydrofluorocarbon. Included in this invention are compositions of a cyclic or acyclic hydrofluoroether of the formula CaFbH2a+2?bOc wherein a=2 or 3 and 3≦b≦8 and c=1 or 2 and a hydrofluorocarbon of the formula CnFmH2n+2?m wherein 1≦n≦4 and 1≦m≦8. Such compositions may be used as refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.

Relative Rate Constants for the Reactions of CF3OF with Olefins in Solution

The addition reactions of CF3OF to chloro fluoro olefins have been studied in solution at low temperature (-78, -105 deg C), and their relative rate constants have been determined using the kinetic approach of competition reactions.The reactivity and regio- and stereoselectivity are consistent with a free radical chain-propagating reaction in which the alkenes are attacked by the CF3O* radical generated by homolytic cleavage of the O-F bond in the CF3OF molecule.
