COMPOSITION INCLUDING FLUOROMETHANE AND METHOD FOR PRODUCING SAME

An object of the present invention is to provide a composition containing fluoromethane having high purity. A method for producing fluoromethane, comprising: pyrolyzing in a gas phase a fluorine-containing methyl ether represented by Formula (1): wherein R1 and R2 are the same or different, and each represents an optionally substituted linear or branched monovalent aliphatic hydrocarbon group, an optionally substituted monovalent aromatic hydrocarbon group, an optionally substituted monovalent cyclic aliphatic hydrocarbon group, hydrogen, or halogen, in the presence of an alumina catalyst to thereby obtain a mixed gas containing fluoromethane and acid fluoride, wherein: the alumina catalyst contains chlorine in an amount of 1.0 wt % or less.

METHOD FOR PRODUCING DRY ETCHING GAS

Provided is a method for producing fluoromethane and 3,3,3-trifluoro-2-(trifluoromethyl)propanoyl fluoride ((CF3)2CHCOF), which are useful as dry etching gases etc., safely and inexpensively with high purity. According to the method in which 1,1,3,3,3-pentafluoro-2-trifluoromethylpropyl methyl ether is pyrolyzed in a gas phase in the presence of a catalyst, the desired fluoromethane and 3,3,3-trifluoro-2-(trifluoromethyl)propanoyl fluoride can be obtained with high selectivity and high conversion of the starting material by a simple process in which a pyrolysis reaction is performed in a gas phase using the inexpensive starting material.

Fluorinated Pyrones and Cyclobutenecarboxylates

Fluorinated α-pyrones 6 have been prepared from perfluoroacryloyl fluorides 1 and 2 by reaction with arylacetylenes and/or methyl ketones.Cyclobutenecarboxylates 8 have also been obtained from the reactions of 1 with acetylenes.The NMR spectrum of pyrone 6e shows unusually long-range fluorine-fluorine coupling.
