Abstract: Disclosed herein is a process of preparing octafluorocyclohexadiene using hexafluorobenzene as a raw material. The hexafluorobenzene reacts with an activated fluorinating agent at 60-200° C. in an inert gas atmosphere. The activated fluorinating agent is prepared by mixing 1-10 wt % of cobalt difluoride with 90-99 wt % of other metal fluoride selected from the group of calcium fluoride, magnesium fluoride, aluminum fluoride, sodium fluoride and potassium fluoride. The mixture reacts with fluorine gas at 200-400° C.

Abstract: A process for the production of a fluorinated organic compound, characterized by fluorinating an organic compound having a hydrogen atoms using IF5; and a novel fluorination process for fluorinating an organic compound having a hydrogen atoms by using a fluorinating agent containing IF5 and at least one member selected from the group consisting of acids, bases, salts and additives.

Abstract: Methods of making parylene AF4 using novel that result in reduced cost. Low dilution technology may used to provide parylene AF4 in substantially improved yields. The relative amount of transition metal catalyst can be decreased. The amount of undesired byproduct is also reduced.

Abstract: The present invention relates to a method for preparing a pitch fluoride, which comprises reacting pitch with fluorine in a fluorine type inert medium.

Abstract: Disclosed is a novel fluorocarbon comprising carbon atoms and fluorine atoms and having no double bond, the atomic ratio of fluorine to carbon atoms being 1.50 to 1.93, which exhibits a liquid state at room temperature. The liquid fluorocarbon has excellent water- and oil-repellent properties and can advantageously be used, for example, not only as a water- and oil-repellent but also as an inert liquid, a heat transfer agent and a vapor phase soldering liquid in various fields, especially in the electronic industry. The liquid fluorocarbon can be obtained directly from a pitch or from a pitch fluoride which can be obtained by direct fluorination of a pitch.

Abstract: A process for introducing a fluorine atom into an aromatic hydrocarbon by effecting a substitution reaction between an aromatic hydrocarbon and an NF.sub.4.sup.+ cation containing salt.

Abstract: Allylbenzene is converted to indene by means of a tungsten-containing catalyst.
