There are many types of specialty fluorochemicals with important applications. They are usually quite expensive and are used in small quantities. Here are some examples. Fluorinated surfactants, significant as they are, are consumed in relatively small quantities. They have not been included in this book because there are already competent books about them [22].

Another group of “fluorinated” compounds are drugs and pharmaceuticals, nearly 20%, containing one or more atoms of fluorine in their structures. Examples of common medicine containing fluorine include Prozac, Cipro and Paxil. In spite of minor presence in the structure of drugs fluorine atom affects the characteristics of pharmaceutical substantially. They are not covered in this book because a separate volume would be needed for their coverage. Journal articles and other books continue to publish information about research and development of new fluorinated chemicals synthesized [23–25].

Another important group of fluorocarbons are used in surgeries as inhalation anesthesia. The benefits over the old compounds include non-toxicity, non-flammability, general metabolically stability, ease of detoxification in the liver, rapid recovery and very few side effects. Commercial examples of those fluorocarbons include methoxyflurane, isoflurane, sevoflurane and desflurane. A popular compound was enflurane which is no longer commonly used but it is effective in relaxing the uterus in pregnant women.
