What happens when oil is heated repeatedly?
When oil is heated repeatedly, a series of chemical reactions occur that can significantly alter its physical and chemical properties. The process, known as thermal degradation, begins when the oil reaches a certain temperature, typically around 300°C. As the oil heats up, its molecular structure begins to break down, causing it to become more viscous and thicker. This is because the heat causes the long, complex hydrocarbon chains in the oil to become more rigid and entangled with one another.
As the oil is heated further, the chemical reactions become more severe. Hydrogen molecules begin to detach from the hydrocarbon chains, forming smaller molecules such as water, carbon monoxide, and carbon dioxide. These byproducts are released into the air, leading to the characteristic odor of burning oil.
The thermal degradation of oil also produces a variety of undesirable compounds, including polycyclic aromatic hydrocarbons (PAHs) and nitrogen-containing compounds. PAHs are known carcinogens that can cause cancer and other health problems, while nitrogen-containing compounds can contribute to air pollution and smog.
Over time, the repeated heating and cooling of oil can cause it to become more brittle and prone to cracking. This can lead to the formation of sludge and deposits in the oil, which can further impede its flow and damage the equipment it is used in.
To prevent the thermal degradation of oil, it is recommended to store it in cool, dark places and avoid exposing it to extreme temperatures or prolonged heating. Regular filtration and maintenance of oil-using equipment can also help to prevent the buildup of sludge and deposits.
