The present invention is aimed to provide a highly-productive method for producing a stabilized fluoropolymer. The present invention relates to a method for producing a stabilized fluoropolymer, comprising the step of bringing a fluoropolymer to be treated into contact with a fluorinating agent to produce a stabilized fluoropolymer, while maintaining the concentration of hydrogen fluoride present in a reaction vessel at not higher than 1.0% by volume.

Method for producing stabilized fluoropolymer

A particulate material processing apparatus has a vessel and a processing tank. The vessel has a charging port for charging a particulate material into the vessel. The processing tank receives the particulate material charged from the charging port. The processing tank is shaped so as to narrow towards the bottom. At least the lower part of the processing tank is made of a gas-permeable material that allows the process gas for processing the particulate material to pass through. The upper part of the processing tank has lower gas permeability than the lower part of the processing tank.

There is provided a fluorine storage material comprising a novel fluorinated carbon nanohorn, which stores a large amount of fluorine per its unit mass, withstand repeated use for fluorine storage, and enables a high purity fluorine gas to be taken out by a safe and efficient method, and also there is provided a method of taking out a fluorine gas by applying heat to the fluorine storage material or placing the fluorine storage material in a pressure-reduced atmosphere.

Fluorine storage material

There is provided a process for the production of iodine pentafluoride which avoids the problems of the production process of iodine pentafluoride of the prior art as much as possible, and which carries out the reaction of fluorine and iodine moderately, so that iodine pentafluoride is produced more safely and more productively. In the process for the production of iodine pentafluoride by reacting fluorine and iodine, fluorine is supplied to the gas phasewhich is adjacent to the liquid phaseof iodine pentafluoride which contains iodine.

A particulate material processing apparatus has a vessel, a processing tank, and a dispersing member. The vessel has a charging port for charging a particulate material into the vessel. The processing tank receives the particulate material charged from the charging port. The processing tank is shaped so as to narrow towards the bottom. At least the lower part of the processing tank is made of a gas-permeable material that allows the process gas for processing the particulate material to pass through. The dispersing member is disposed below the charging port. The dispersing member disperses and flattens the particulate material on the processing tank.
