what happens when oil is heated repeatedly?
When oil is subjected to repeated heating, a series of changes occur, gradually altering its properties and composition. Initially, the oil undergoes a process called polymerization, where individual oil molecules combine to form larger, more complex structures. This results in an increase in the oil’s viscosity and a darker color. As heating continues, the oil begins to break down, releasing volatile compounds and producing a pungent odor. These volatile compounds can be harmful if inhaled, and they can also contribute to the formation of air pollution. Additionally, the oil undergoes oxidation, a reaction with oxygen that further degrades its chemical structure. This process can lead to the formation of gums and deposits, which can clog equipment and hinder its performance. Repeated heating of oil can also result in the formation of free radicals, which are highly reactive molecules that can damage equipment and contribute to the aging process.
