    摘要： F(CF2)n(CH2)mNH2 is produced in high yield, while reducing the amount of by-products contained in the reaction product and preventing the reactor from corroding. Provided is a process for producing a fluorinated alkylamine compound, which comprises reacting a compound represented by F(CF2)n(CH2)mX (wherein X represents a chlorine atom, a bromine atom or an iodine atom, and n and m each independently represents an integer of at least 1) with NH3 to produce a compound represented by F(CF2)n(CH2)mNH2 (wherein n and m have the same meanings as the above), and is characterized by conducting the reaction in the presence of a reaction solvent comprising an alkanediol as an essential component.

    摘要： The present invention provides a process whereby fluorinated ketones of various structures can be produced by short process steps and which is useful as an industrial production process. Namely, it is a process for producing a fluorinated ketone of the following formula (5), which comprises reacting a compound of the following formula (3) having a fluorine content of at least 30 mass %, with fluorine in a liquid phase to obtain a compound of the following formula (4), and then, subjecting the ester linkage of the compound of the formula (4) to a dissociation reaction:RCCOOCHRARBnullnull(3)RCFCOOCFRAFRBFnullnull(4)RAFRBFCnullOnullnull(5)wherein each of RA and RAF are each a monovalent organic group such as an alkyl group, or RA and RB may be bonded to each other to form a bivalent organic group such as an alkylene group, RAF and RBF are a monovalent organic group such as a perfluoroalkyl group formed by fluorination of RA and RB, or they are bonded to each other to form a bivalent organic group such as a perfluoroalkylene group, and RC and RCF are each a monovalent organic group such as a perfluoroalkyl group which may contain an etheric oxygen atom.
