    摘要： A process for producing a high-purity fluorinated alcohol in a good purification yield, is provided. In a process for producing a fluorinated alcohol, which comprises reacting methanol with tetrafluoroethylene or hexafluoropropylene in the presence of an alkyl peroxide, the reaction liquid after completion of the reaction is distilled in the presence of water and HF to separate it into a fraction containing an alcohol derived from the alkyl peroxide and a bottom liquid containing the fluorinated alcohol, and then, the bottom liquid is purified to recover the fluorinated alcohol.

    摘要： The present invention provides a method for obtaining a compound useful as a raw material for various fluororesins in high yield by a short process by using a starting material which is inexpensive and readily available. Namely, the present invention is characterized by reacting the following compound (1) with the following compound (2) to produce the following compound (3) having a fluorine content of at least 30 mass %, fluorinating the compound (3) in a liquid phase to produce the following compound (4), followed by a cleavage reaction of EF of the compound (4) to obtain a compound (5) and/or a compound (6): E1-RA-E1nullnull(1) E2-RBnullnull(2) RB-E-RA-E-RBnullnull(3) RBF-EF-RAF-EF-RBFnullnull(4) EF1-RAF-EF1nullnull(5) RBF-EF2nullnull(6) wherein RA is a fluorine-containing bivalent organic group which is the same as RAF, or a bivalent organic group which will be converted to RAF by a fluorination reaction, and RB is a monovalent organic group which is the same as RBF, or a monovalent organic group which will be converted to RBF by a fluorination reaction, RAF is a fluorine-containing bivalent organic group which is the same as or different from RA, and when different, it is a group having RA fluorinated, RBF is a fluorine-containing monovalent organic group which is the same as or different from RB, and when different, it is a group having RB fluorinated, E1 and E2 are reactive groups which will react to each other to form a bivalent connecting group (E), E is a bivalent connecting group formed by the reaction of E1 and E2, EF is a group which is the same as E, or a group having E fluorinated, provided that at least one selected from RAF, RBF and EF, is a group formed by a fluorination reaction, and each of EF1 and EF2 which are independent from each other, is a group formed by cleavage of EF.
