Kerosene is a water-white liquid first obtained by Abu Baker Al Razi in the 9th centuryKnown in the UK and South
Africa as “Paraffin” and inThe US, Canada, and Australia
as “Kero”Known in Egypt as “Gas”

Though its importance has much declined recently, kerosene finds the following applications:1. Fuel:
Heating and cooking (Stove Kerosene): widely used in Japan for heating (Kerosene Heaters) and in portable stoves (e.g: primus) in some
less developed countries

1. Fuel: Illumination (Illumination Kerosene): formerly used for lightening purposes (Wick Lamp) Power Kerosene: Used as a fuel in tractors
2. Others: Used sometimes as an additive to diesel to
prevent waxing at low temperatures Used to produce LAB, an important
petrochemical that is used in detergent industries

2. Others: Used to remove lice from hair, though it has
been limited since the process is painful and dangerous
Used in fire dancing in some cultural performances
Used to treat poolsOf standing waterTo prevent mosquitoesFrom breeding

Like any petroleum fraction, kerosene has some specifications to determine its quality
Due to the various uses of kerosene; the concept of relative quality appears
The following slides discuss some important specifications for kerosene

1. Flash Point: ◦ Defined as the minimum
temperature at which enough vapors are found to produce a surface of combustion of the fuel when heated in a standard apparatus under standard conditions
◦ This spec is important for light fractions to determine storage and handeling precautions
