Kerosene has a rich history dating back to the mid-19th century. It was first distilled from coal by Canadian geologist Abraham Gesner in 1846. The discovery of kerosene provided a safer and more efficient alternative to whale oil for lighting. By the late 19th century, kerosene became widely used for lamps, heating, and cooking, particularly in rural areas without access to electricity.
Common Uses
Kerosene has various applications, making it an essential energy source worldwide. Some of the most common uses include:
- Heating and Lighting: Kerosene heaters and lamps are still used in many parts of the world, especially in remote and rural areas.
- Aviation Fuel: Kerosene is a key component in jet fuel, providing the necessary energy for commercial and military aircraft.
- Cleaning Solvent: Kerosene is used as a solvent in industries for cleaning and degreasing machinery and tools.
What is Turpentine?
Definition and Composition
Turpentine is a volatile liquid obtained by distilling resin from pine trees. It consists mainly of terpenes, including pinene, camphene, and limonene. Turpentine is known for its strong, pungent odor and is commonly used as a solvent and in medicinal applications.
Historical Background
Turpentine has been used for centuries, dating back to ancient civilizations. It was originally obtained by tapping pine trees and collecting the resin. The resin was then distilled to produce turpentine oil. In the 18th and 19th centuries, turpentine production became a significant industry in the southern United States, particularly in states like North Carolina and Georgia.
Common Uses
Turpentine has a variety of applications, primarily due to its solvent properties. Some of the most common uses include:
