The Difference Between Coal Oil and Kerosene
Source
Coal oil is derived from cannel coal, a soft, oily coal that contains bitumen, a form of petroleum. It is obtained through a process called destructive distillation. Kerosene, on the other hand, is directly refined from liquid petroleum, also known as crude oil.
Historical Confusion
In the past, there was some confusion between the terms “coal oil” and “kerosene,” leading to inconsistencies in historical records and stories. However, in modern times, “kerosene” is generally accepted as the term referring to an oily substance obtained during the refining and distillation of petroleum. It is important to be aware of this historical confusion to avoid misinterpretation when studying historical documents.
Chemical Composition
Both coal oil and kerosene are primarily composed of hydrocarbons from the alkane series. Each molecule of these fuels contains between 10 and 16 carbon atoms. However, the specific composition of coal oil and kerosene may vary depending on their sources and the refining processes involved.
Boiling Point
The boiling points of coal oil and kerosene differ significantly. Coal oil has a higher boiling point, ranging from 175°C to 325°C (347°F to 617°F). This boiling point is higher than that of gasoline or petroleum ethers. On the other hand, kerosene has a lower boiling point compared to coal oil.
Conclusion
In summary, coal oil and kerosene are distinct fuels with differences in their sources, historical usage, chemical composition, and boiling points. Coal oil is derived from cannel coal, while kerosene is directly refined from liquid petroleum. While there was some historical confusion between the terms, modern usage differentiates between the two. Both fuels are primarily composed of hydrocarbons from the alkane series, but their specific compositions may vary. Additionally, coal oil has a higher boiling point compared to kerosene.
Understanding these differences is crucial for accurate interpretation and application in various contexts.
FAQs
What is coal oil?
Coal oil is a fuel derived from cannel coal, a soft, oily coal that contains bitumen, a form of petroleum. It is obtained through a process called destructive distillation.
How is kerosene different from coal oil?
Kerosene is a fuel that is directly refined from liquid petroleum, also known as crude oil. Unlike coal oil, which is derived from cannel coal, kerosene is obtained from petroleum through refining and distillation processes.
Can coal oil and kerosene be used interchangeably?
No, coal oil and kerosene cannot be used interchangeably. While they are both fuels, they have different chemical compositions and boiling points, which affect their properties and performance in various applications.
What is the chemical composition of coal oil and kerosene?
Both coal oil and kerosene are primarily composed of hydrocarbons from the alkane series. Each molecule of these fuels contains between 10 and 16 carbon atoms. However, the specific composition may vary depending on their sources and the refining processes involved.
How do the boiling points of coal oil and kerosene compare?
Coal oil has a higher boiling point ranging from 175°C to 325°C (347°F to 617°F), which is higher than that of gasoline or petroleum ethers. In contrast, kerosene has a lower boiling point compared to coal oil.
What are the applications of coal oil?
Historically, coal oil was widely used for illumination before the advent of electric lighting. It was commonly used in lamps and lanterns. However, its usage has diminished over time with the availability of alternative fuels and energy sources.
What are the applications of kerosene?
Kerosene has various applications. It is commonly used as a fuel for jet engines, heating, and lighting in certain contexts. It is also used as a solvent and in the production of certain industrial products.
Are there any safety considerations when handling coal oil and kerosene?
Both coal oil and kerosene are flammable substances and should be handled with care. It is important to follow proper safety precautions when storing, transporting, and using these fuels to minimize the risk of accidents or combustion.
