Title:
IMPROVEMENT IN PRODUCTION OF TRIFLUOROMETHYLOXIRANE
Document Type and Number:
Japanese Patent JPH10279571
Kind Code:
A
Abstract:
To provide a method for producing trifluoromethyloxirane having advantages exceeding those of a conventional method.
3-Chloro-1,1,1-trifluoroacetone is reduced in the presence of an inert solvent and a proton donor is then added to the reactional mixture to thereby provide 3-chloro-1,1,1-trifluoro-2-propanol. Hydrogen chloride is further eliminated therefrom at a lower temperature than 70°C to cyclize the resultant 3-chloro-1,1,1-trifluoro-2-propanol by actions of an alkaline aqueous solution.
