A shaped body of a fluororesin obtained using a shaping material comprising a powder of a fluororesin. The powder of the fluororesin has a static bulk density of 0.3 g/ml or more and 1.5 g/ml or less, and a particle diameter of 10 μm or more and 300 μm or less in terms of D50. Also disclosed is a three-dimensional structure containing the shaped body, and a method of shaping the shaping material.

Shaping powder

A molded body which is formed from a shaping material containing a fluororesin powder. The fluororesin powder has a D50 of 30 μm or more and 200 μm or less and a D10 of 12 μm or more. Also disclosed is a method for forming a molded body from a shaping material containing the fluororesin powder, the method including controlling the temperature of the fluororesin powder; and irradiating the fluororesin powder with a laser at the controlled temperature to fuse the same.

Molding powder

A shaping material for a powder bed fusion method, containing a powder of a fluororesin.

A shaping material for a powder bed fusion method, including a powder of a fluororesin, wherein the fluororesin has a D50 of 30 &#x3bc;m or more and 200 &#x3bc;m or less, and the fluororesin has a D10 of 12 &#x3bc;m or more.

The present invention provides a method for producing a fluorine-containing halide, comprising reacting a fluorine-containing sulfonyl halide or fluorine-containing disulfonyl chloride with a metal halide or metal component in the present or absence of a solvent. In accordance with the present invention, a fluorine-containing bromide, fluorine-containing iodide or fluorine-containing chloride can be readily produced in high yield at low cost, using an industrially advantageous process.

Method for producing fluorine-containing halide

The present invention provides a process for selectively separating HF and like acids present along with water-unstable organic acid fluorides. In particular, the invention provides a process for separating an acid from a system in which the acid and an organic acid fluoride are present, the organic acid fluoride being represented by formula (I):RCOF&#x2003;&#x2003;(I)wherein R is a fluorine atom; a Clinear, branched or cyclic alkyl or halogenated alkyl group that may contain a heteroatom; or a Caryl or halogenated aryl group that may contain a heteroatom; the process comprising using as a deacidifying agent an aromatic heterocyclic compound having a boiling point of at least 50&#xb0; C. and having one or more nitrogen atoms as heteroatom.

Method of separating acid

The present invention relates to a method for producing a fluorocopolymer which comprises a polymerization reaction of a fluorine-containing ethylenic monomer with a fluorovinyl ether derivative represented by the following general formula (I):CF&#x2550;CF&#x2014;O&#x2014;[CFCF(CF)O]&#x2014;(CF)-A&#x2003;&#x2003;(I)(wherein n represents an integer of 0 to 3, m represents an integer of 1 to 5, and A represents &#x2014;SOX or &#x2014;COOY; X represents a halogen atom or &#x2014;NRR; Rand Rare the same or different and each represents a hydrogen atom, an alkali metal, an alkyl group or a sulfonyl-containing group and Y represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms) to give a fluorocopolymer, said fluorine-containing ethylenic monomer being a perhaloethylenic monomer represented by the following general formula (II):CF&#x2550;CF&#x2014;R&#x2003;&#x2003;(II)(wherein Rrepresents a fluorine atom, a chlorine atom, Ror OR; Rrepresents a straight or branched perfluoroalkyl group having 1 to 9 carbon atoms, which may have an ether oxygen atom(s)) and/or a hydrogen-containing fluoroethylenic monomer represented by the following general formula (III):CHX&#x2550;CFX&#x2003;&#x2003;(III)(wherein Xrepresents a hydrogen atom or a fluorine atom and Xrepresents a hydrogen atom, a fluorine atom, a chlorine atom, Ror OR; Rrepresents a straight or branched perfluoroalkyl group having 1 to 9 carbon atoms, which may have an ether oxygen atom(s)), and said polymerization reaction being carried out in a saturated perfluorohydrocarbon while additional feeding of the fluorine-containing ethylenic monomer and fluorovinyl ether derivative being carried out.
