GENERAL DESCRIPTION & APPLICATIONS
Higher chain alkanes have less use in the petrochemical industry due to high flash point making it an inefficient fuel. They are used as lubricants, transformer oils, and anti-corrosion agents. They are chemically inactive. They are parts of the paraffin or wax. Biologically occurring in nature (bacteria, bungi, plants or animals ) higher chain alkanes do not rank biologically among the essential materials, but they play an important roll in pheromones that acts as a chemical messenger, transmitting information from one member of a species to another member of the same species.
