Kerosene, also known as paraffin, is a flammable hydrocarbon liquid derived from the distillation of crude oil. It is a clear, colorless to yellowish substance with a distinctive odor, typically consisting of hydrocarbons in the C10 to C16 range.
History:
Discovered in the mid-19th century, kerosene was first commercially produced by Canadian geologist Abraham Gesner in the 1840s as an alternative to whale oil for lighting. It gained widespread use during the Industrial Revolution for lamps and heaters, and later became essential in aviation and transportation.
Properties:
Kerosene has a boiling point ranging from 150°C to 300°C, a density of about 0.78-0.81 g/cm³, and a flash point around 38°C, making it less volatile than gasoline but still highly flammable. It is soluble in organic solvents and provides a high energy density, with an energy content of approximately 46.5 MJ/kg.
Uses:
Primarily used as a fuel for jet aircraft (as in Jet A-1 fuel), kerosene powers turbines in aviation. It is also employed for domestic heating in stoves and heaters, lighting in lamps, and as a solvent in industrial applications like cleaning and pest control. In some regions, it serves as a cooking fuel in portable stoves.
Production and Refining:
Kerosene is obtained through fractional distillation of crude oil, where it is separated based on its boiling point. Refining processes include hydrotreating to remove impurities, ensuring it meets standards like those set by ASTM International for safety and performance.
Safety and Environmental Considerations:
While efficient, kerosene combustion produces carbon dioxide and other pollutants, contributing to air pollution and climate change. It is hazardous if mishandled, with risks of fire, explosion, and health issues from inhalation or skin contact. Proper storage in ventilated areas and use of safety equipment are essential. Environmentally, efforts are underway to develop bio-kerosene from renewable sources to reduce fossil fuel dependency.

B) Hydrocarbons
C) Acids
D) Esters
Answer: B
Explanation: Kerosene consists mainly of hydrocarbons, specifically paraffins, naphthenes, and aromatic hydrocarbons, derived from petroleum.
6. Question: In which year was kerosene first commercially produced?
Options:
A) 1850
B) 1846
C) 1900
D) 1920
Answer: B
Explanation: Kerosene was first commercially produced in 1846 by Abraham Gesner, who patented a process for distilling it from coal and oil.
7. Question: What safety precaution is essential when handling kerosene?
Options:
A) Storing it near open flames
B) Using it in unventilated areas
C) Keeping it away from ignition sources
D) Mixing it with water
Answer: C
Explanation: Kerosene is highly flammable, so it must be stored and handled away from ignition sources to prevent fires or explosions.
