Title:
METHOD FOR PRODUCING FLUORINATED DI-SALT COMPOUND AND METHOD FOR PRODUCING FLUORINATED VINYL COMPOUND
Document Type and Number:
Japanese Patent JP2022070150
Kind Code:
A
Abstract:
To provide a method that makes it possible to produce a fluorinated di-salt compound (4) without using water or alcohol, and further provide a method that uses the fluorinated di-salt compound (4) produced thereby to reduce the amount of use of an ether compound (3) and produce a fluorinated vinyl compound (5) even at low temperatures.SOLUTION: The present invention pertains to a method for producing a fluorinated di-salt compound (4). The method includes a reaction between a fluorinated carboxylic fluoride (1) and an alkali metal carbonate (2) in the presence of an ether compound (3). The ratio (β/α) of the amount of substance (β) of the alkali metal carbonate (2) to the amount of substance (α) of the fluorinated carboxylic fluoride (1) is more than 2. The ratio (δ/γ) of the mass (δ) of the ether compound (3) to the mass (γ) of the fluorinated carboxylic fluoride (1) is 0.55 or less. There is also provided a method for producing a fluorinated vinyl compound (5) by heating the fluorinated di-salt compound (4) produced by the method.SELECTED DRAWING: None
