Abstract: Fluorine gas is introduced to a raw material liquid containing a reaction inducer and a fluorinated hydrocarbon represented by CpHqClrFs (in the formula, p is an integer of 3 to 18, q is an integer of 0 to 3, r is an integer of 0 to 9, and s is an integer of 5 to 30) and having no carbon-carbon unsaturated bond to give tetrafluoromethane. The reaction inducer is a halogen-containing carbon compound liquid at room temperature and pressure and is reacted with fluorine gas to induce a reaction of forming tetrafluoromethane from the fluorinated hydrocarbon and the fluorine gas. The reaction inducer is contained at a content of more than 0% by mass and not more than 10% by mass when the total content of the fluorinated hydrocarbon and the reaction inducer contained in the raw material liquid is 100% by mass.

Abstract: Provided is a method for producing hexafluoro-1,3-butadiene, and the method can produce hexafluoro-1,3-butadiene at an industrially sufficient level of yield. In a reaction liquid containing a halogenated butane represented by chemical formula, CF2X1—CFX2—CFX3—CF2X4 (X1, X2, X3, and X4 are each independently a halogen atom other than a fluorine atom), zinc, and an organic solvent, a reaction is conducted to eliminate the halogen atoms other than a fluorine atom, X1, X2, X3, and X4, from the halogenated butane, yielding hexafluoro-1,3-butadiene. During the reaction, the concentration of a zinc halide generated by the reaction, in the reaction liquid is not more than the solubility of the zinc halide in the organic solvent.

Abstract: A magnetic recording medium includes a non-magnetic substrate, a soft magnetic underlayer, an orientation control layer, a perpendicular magnetic layer, and a protective layer arranged in this order. The perpendicular magnetic layer includes a first magnetic layer and a second magnetic layer from the non-magnetic substrate side in this order. The second magnetic layer contains a magnetic grain and provided farthest from the non-magnetic substrate. The first magnetic layer has a granular structure that contains an oxide in a grain boundary. The second magnetic layer has a granular structure that contains a nitride of an element contained in the magnetic grain in a grain boundary.
