Perfluorinated compounds are fluorocarbon derivatives, as they are closely structurally related to fluorocarbons. These are mainly binary mixtures of hydrocarbons, fluorocarbons, hydrofluorocarbons, siloxanes and inorganic substances. Formally, fluorocarbons only contain carbon and fluorine. The resulting HF is converted into fluorine, fluorocarbons, and diverse fluoride materials. PTFE gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons. By contrast, fluorosurfactants are not amphiphilic or detergents because fluorocarbons are not lipophilic. Unsaturated fluorocarbons are far more reactive than fluoroalkanes. Like all unsaturated fluorocarbons, it is susceptible to nucleophilic attack. Fluorocarbons can be perfluoroalkanes, fluoroalkenes and fluoroalkynes and perfluoroaromatic compounds. In the 1960s there was a lot of interest in fluorocarbons as anesthetics. In 1993, 3M considered fluorocarbons as fire extinguishants to replace CFCs. Potassium fluoride is used for the conversion of chlorocarbons into fluorocarbons.. It reacts with potassium fluoride to give the corresponding fluorocarbons. Fluorocarbons also have low surface energies and high dielectric strengths. He held patents in the fields of plastics, fluorocarbons, and electronics.
