Document Type and Number:
WIPO Patent Application WO/2021/025012
Kind Code:
A9
Abstract:
Provided are: a method for purifying a phosphorus-containing olefin compound salt of a raw material or intermediate that can be applied to a method for producing an olefin compound, the purification method being useful for raising the purity of a target substance in the production method; and a method for producing an olefin compound using the purified product obtained thereby. Specifically, provided is a method for purifying a phosphorus-containing olefin compound salt, the method having a step for obtaining a purified product of the phosphorus-containing olefin compound salt by re-precipitating and/or re-crystallizing, in a solvent, a solid that contains at least one phosphorus-containing olefin compound salt selected from the group consisting of phosphorus-containing olefin compound salts A represented by general formula (1) [in the formula, X1 and X2 independently represent F, Cl Br, I, or H; W+ are the same or different monovalent cations comprising PR3 or POR3 (where R are groups having a saturated or unsaturated structure including C and H, and R may bond to each other to form a ring and may include atoms other than C and H); the three R included in the R3 may be the same or different; M- represents a monovalent anion comprising an atom or a compound] and phosphorus-containing olefin compound salts B represented by general formula (2) [in the formula, X1, X2, W+, and M- are the same as above; Y represents F, Cl, Br, I, H, an alkyl group, an alkyl ether group, a fluoroalkyl group, or a fluoroalkyl ether group].
